Portability of xpath?
Quick question about the use of xpath.
I notice you can write custom xpath expressions and it looks like there are xpath expressions available with an oracle namespace. If i were to use one of these functions in my Bpel process and then later decide to swich to a non-oracle bpel engine would these expressions still be able to run? Are they portable?
I guess Iam asking, if i want to keep things flexible/open/portable should i stick to using the generic functions?
thanks, Alex
Probably it is referred to the fact that it is a small box, so you can easily put it inside your pockets or on the shelfs.
Bye Alessandro

Hello
I have been reading forums and forums and after days of research l gave up.
Unfortunately it seems that nobody has provided a name of a brand yet.
Although the effort is very admirable, l am still at the point of finding myself back at square one, with an unanswered question:
Which portable external HD 500GB should l purchase for my iMac 10.4.11 (Power PC 2004)?
I know there are many different ones, but l hope at least somebody can suggest one.
A clear Name of a Product that matches the compatibility.
I am not an expert of computer and so all the theoretical explanations of technical characteristics mean next to nothing to me :(
I hope that someone kind enough to halo me out with this will be able to let me know.
My most greatefull thank you to you all in advance :)

Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
YOUR MAC WILL THANK YOU
Hey all.
Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue
I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
User Software Symptoms :
Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
Possible Hardware Symptoms:
Your computer is making more noise than it did previously.
Your computer occasionally makes more noise but then gets quieter.
Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
After trying many different things to solve this problem such as :
PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
After much testing I found the problem :
It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
One app shows fan speed, and CPU heat, etc.
One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
One app is a dashboard widget, the other is a system preference.
I suggest you download both of these to check your computer statistics.
http://www.eidac.de/?p=134
http://www.islayer.com/apps/istatpro/
http://fan-control.en.softonic.com/mac
I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
If a bad fan is your problem :
THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
Fix or replace your fan so it cools the CPU and other chips properly.
I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new. It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
How to fix / replace your internal fan on a mid 2009 MacBook Pro :
Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
Before you begin:
Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):
http://www.youtube.com/watch?v=AghE9newvbs
Check out someone's web page (not mine) on how to replace the fan in a mid 2009 MacBook Pro:
http://www.ifixit.com/Guide/Installing-MacBook-Pro-13-Inch-Unibody-Mid-2009-Fan/ 1338/1
How to repair your mid 2009 MacBook Pro fan:
Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc.
Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
3. Unscrew the fan's 3 holding screws.
4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
5. Remove the fan - it easily lifts out.
6. Take the fan apart by unscrewing it's one screw then unlatching the plastic clips which hold it together.
7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
Screw together the fan housing then reclip the clips.
11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
14. Double check you didn't forget anything like screws, tools, etc.
15. Boot up your Mac and monitor the temperature and fan speed using those programs.
Compare the previous temps/fan speed to the current temp/fan speed.
Run a high CPU intensive app where your computer has been slowing down.
You should now have a happy Mac
If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
Hope that helps.Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

How hard is it to set up Elements/CS5 to access photo's off of portable hard drive so I can free up
I have down loaded approximately 4000 files to an external 1 terabite portable drive ( Western Digital, My Passport ) from my laptop to free up space. I would like to access the photo's for editing in both elements 11 and CS5, and Lightyear 3. I have not deleted the originals off of my laptop yet until I know it will work, or more correctly, how to make it work. When I connected the portable drive to the laptop afterwards, the downloader wanted to download the 4000+ photo's back on to my laptop. Specs- ASUS N53S, 8 mb Ram, Core i7, Windows 7, about 116 GB harddrive. Can anyone help me with the steps needed to make this work so that I can take the photo's of my laptops hard drive but still have easy access to them with the portable drive ? Thanks, Mike
Normally you can plug in the external drive and then simply drag and drop folders after clicking on the yellow pins in the Organizer left hand panel. You don’t say if you are using Organizer.
The complication is that if you are also using Lightroom 3 with the same image files, that will corrupt the file paths in the Lightroom Library. It would be easier if you are not using Organizer and restrict your file management to LR with CS5 and the PSE11 Editor set up as your external editing applications.
The safest method is probably to first select the 4000 images in LR3 and save XMP/Metadata to the files. Then move the images to My Passport and re-import into LR3. If that works satisfactorily you can delete the original folders from LR and click the button - Delete also from Disk. -
XPath expression failed to execute.
Hi Everybody ,
I am working AIA PIP 3.1 for JDE E1.I am facing some errors so that i can't proceed.
See the log errors as below:

An error occurs while processing the XPath expression; the expression is ora:processXSLT('xsl/Xform_BillOfMaterialsListABM_to_BillOfMaterialsListAXML.xsl',bpws:getVariableData('InitialLoadBillOfMaterialsListReqMsg','InitialLoadBillOfMaterialsList'),bpws:getVariableData('Parameters')). The XPath expression failed to execute; the reason was: oracle.fabric.common.xml.xpath.XPathFunctionException: javax.xml.transform.TransformerException: oramds:/deployed-composites/default/InitialLoadBillOfMaterialsListJDEE1toAgileImpl_rev1.0/xsl/Xform_BillOfMaterialsListABM_to_BillOfMaterialsListAXML.xsl<Line 18, Column 271>: XML-22044: (Error) Extension function error: Error invoking 'lookupXRef':'oracle.tip.xref.exception.RepositoryException: lookup could not find values in column name "AGILE_01" for table name "oramds:/apps/AIAMetaData/xref/ITEM_ITEMID.xref" using reference column name "JDEE1_01" and reference value "731882::M30" Please ensure lookup criteria has a match.'. Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
Please reply me ASAP,
Waiting for your response.....

Jyoti NayakHi,
Ya i checked the data for same table,but i didn't get any XREF related information in xref_data table.
Did you mean that, data should already present under AIAFPINST_XREF.Probably xref is meant for storing dynamic value.
Please check the above error and reply me soon.
With Regards

Problem retrieving a list of values with XPATH
Hi,
I am trying to get a list of all 'Fields' (under the SubscriptionList -> EconomicIndicator -> Code) which have 'Provider' =DJ.
I am using the below xpath expression. But It is not working. I tried other variations but none of them return mulitple items.
Can some one please tell me if Iam missing something.
XPathExpression xPathExpression= xpath.compile("/SubscriptionList/EconomicIndicator[*]/Code[Provider=DJ]/Fields");
NodeList result = (NodeList)xPathExpression.evaluate(doc, XPathConstants.NODESET);
for (int i = 0; i < result.getLength(); i++) {
Element element = (Element)result.item(i);
System.out.println(element.getNodeValue());

</SubscriptionList>Hi DrClap,
I have a similar problem again. This time I am trying to extract a list of values from a xsd. Below is the code that I am using.
try{
djxsd = new FileInputStream("djei-3.1.xsd");
XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();
SimpleNamespaceContext nsContext = new SimpleNamespaceContext();
xpath.setNamespaceContext(nsContext);
nsContext.addNamespace("xs", "http://www.w3.org/2001/XMLSchema");
nsContext.addNamespace("xsi","http://www.w3.org/2001/XMLSchema-instance");
+//String exp = "//xs:element/@name/text()";+
String exp = "/xs:schema/xs:group/xs:sequence/xs:element";
XPathExpression xPathExpression= xpath.compile(exp);
NodeList result = (NodeList)xPathExpression.evaluate(doc, XPathConstants.NODESET);
FileOutputStream outputfile = new FileOutputStream("log.txt");
for (int i = 0; i < result.getLength(); i++) {
Element element = (Element)result.item(i);
String output = element.getTextContent().trim();
if(output.length() > 0)
outputfile.write(output.getBytes());
//System.out.println(output);
Highlighted in Itlalics is the actual expression that I want to use. For some reason this is not working .. it returns nothing.
The other expression works. Please let me know if there is anything wrong with the expression.

Talkin' Bout My Generations: A Brief History of Intel-based Portable Macs
During my first four years here at Discussions, I came across a fairly common problem while trying to help folks using Windows on a Mac: very few people I responded to could tell mewhat kind of system they were using. Many were users of portable Macs, so to try and help them out identifying the machines they used, I thought of making a guide to portableidentification. But as I was writing this article two years ago, I got thinking about a more detailed history of the MacBook family from 2006 to 2010. I’ve taken many of the news snippets I’ve read from Macworld magazine and other sources to provide the historical content in this guide and combinedthem with my personal opinions on each model. Specifications where used have been verified by Brock Kyle’s EveryMac.com and by Apple support documents as well as keynote speeches from Apple execs. The opinions provided are those of the author and are independent of Apple, Inc, so in other words, if you feel differently about these machines…
DON’T SHOOT THE MESSENGER!
And now, the guide. Enjoy!
First generation (1G):
These are the only 32-bit Intel Mac portables in the field, sporting Intel Core Duo (“Yonah”) processors from 1.83-2.16 GHz (Early '06, including Glossy)
MacBook
This long-awaited upgrade of the iBook has a port setup comparable to the Mid-'05 iBook--2 USB 2.0, 1 FW400, audi oout, mini video. Also uses an inset keyboard, which drew some groans from the community-at-large when it first launched. Internally, uses an Intel GMA950 graphics system that borrows up to 64 MB as video RAM and adds 16 MB overhead.
Case type: Solid white or black polycarbonate shell
Chipset: Intel 945GM
Standard RAM: 512 MB (432 MB usable)
Maximum RAM: 2.00 GB PC2-5300 DDR2 SDRAM(1968 MB usable)
Pros: Solid performance vs. iBook, goodbasic machine for the Web, hard drive is user-serviceable.
Cons: Poor graphics make this unit ascratch for mid-level business work, games or creative apps; limited RAM, no64-bit support
MacBook Pro
This was Apple's Intel debut, along withthe iMac (Core Duo). Apple flashed a1.67 GHz prototype at Macworld Expo ‘06 that was scratched in production for a1.83 GHz model. Supply chain economicsresulted in an optical drive downgrade to a standard single-layer drive fromthe double-layer drives in the late '05 PowerBooks. It's also the only model in the MacBook Procontinuum not to bear a FireWire 800 port. Although functionally similar to the MacBookthat followed it, this line has discrete graphics by way of AMD's RADEONX1600--up to 256 MB. Slightly revisedversions, rolled in by mid-year, included a glossy display and improved videoRAM.
Case type: Anodized aluminum compositewith plastic edging.
Chipset: Intel 945GM
Standard RAM: 1 GB
Maximum RAM: 2.00 GB PC2-5300 DDR2 SDRAM
Pros: Good step up from PB '05, can runpro apps and games with ease
Cons: limited RAM, no 64-bit support, no DVD±DL support, lack of FW800 abother for some
Second generation (2G):
The 2G portables (“Late 2006” in Applespeak) were a mild speed bump of the 1G lines, replacing the 32-bit Core with the 64-bit Core2 (“Merom”). Processor speeds ranged from 2.0 GHz-2.33 GHz. Apple fixed many 1G shortcomings here, but retained the 945 family chipsets until well into 2007. As aresult of the 945 family’s addressing limitations, usable RAM is limited to 3GB, even when 4 GB can be installed. (See http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-g b-memory-limitation-details.html) Further, Apple has chosen to limitWindows support on these units to Vista; anything else is “use at own risk”.
On the plus side, these 2G portables arethe absolute earliest qualifiers for Mac OS X Lion, albeit with a significantlylimited user experience—that is, many features of note simply are not possible given the nature of the 2G internals.
MacBook
No visible markers set these units apart from the 1G models, and all internals are the same save for the Core2 CPU. These units were slightly revised in 2007 toenable draft 802.11n support; those models shipped in October 2006 and onward could download an update to enable 802.11n. The only way to confirm a 2G MacBook is via software; the Model ID iseither ”2,1” or “2,2”
Case type: Solid white or blackpolycarbonate shell
Chipset: Intel 945GM
Standard RAM: 1 GB (944 MB usable)
Maximum RAM: 3.00 GB PC2-5300 DDR2 SDRAM (2992 MB usable)
Pros: Core2 offers 64-bit support and modest speed boost, max RAM up
Cons: Still comes up short forhigh-demand applications.
MacBook Pro
Functionally similar to its predecessor while retaining the AMD X1600 graphics, the 2G Pro had three notable differences. This line marks the permanent return of the FireWire 800 port—this one’s on the right side. Also back for an encore is the double-layer SuperDrive; Apple’s suppliers finally had the size of optical drive that Apple needed. Like the MacBook, it also gets a lift from the new Core2 CPUs with twice as much L2 cache as their predecessors and their trendier plastic-clad siblings.
Case type: Anodized aluminum composite with plastic edging.
Chipset: Intel 945GM
Standard RAM: 1 GB
Maximum RAM: 3.00 GB PC2-5300 DDR2 SDRAM
Pros: FW800 is back, as is DVD±DL; max RAM up, graphics still strong
Cons: Speed improvement only nominal, Windows Vista support still lacking inspots (X1000-series chips are not DX10 qualified)
Third generation (3G):
The “Mid/Late 2007” portables were somewhat of a redesign from the inside, though they remained similar to 2G models when viewed from without. Common to both lines is the Intel 965 chipset family, best known by its Intel codename, “Santa Rosa”; with it, the system bus got ramped to 800 MT/s while the memory bus remained at 667 MT/s. Here, the Core2 gets another modest speed bump, with standard frequencies ranging from 2.1 GHz-2.4 GHz. At this time, the RAM ceiling was lifted, allowing 4 GB to be used in all models and making theseMacs capable 64-bit machines. Windows x64 variants will run on this class, but it requires Boot Camp 2.1 or higher and some finesse with installing individual software packages since Apple’s installer places a soft block on these units.
Also of note: 3G and 4G MacBook Pros were particularly susceptible to a defect in the NVIDIA graphics chip, which left unchecked would cause these units not to display video, or to show scrambled video. Apple has a current repair program to fixthis issue if you should run across it, but time is running out. Unless you are aware that the defect has been repaired, these models are best avoided
MacBook
By the time the 3G models surfaced, the2G models were dealing with heavy criticism for not being refreshed in sync with the Pro models. Apple had three convincing reasons for such a delay. First came the iPhone EDGE, for which development was a top priority. The delay actually bought some time for Apple to reveal the other two reasons; Intel was providing the GMA X3100 as a companion to the GM965, which in itself was a modest improvement over the GMA 950 used in the first two iterations; and Apple had been working on its latest flagship OS, “Leopard”, released just days before the new MacBook surfaced on All Saints’ Day (11/1). One might say that waiting does indeed payoff, judging from Macworld’s bench scores of the 3G MacBooks, 2007 was a good year to upgrade the old iBook to something better.
Case type: Solid white or black polycarbonate shell
Chipset: Intel GM965
Standard RAM: 1 GB (880 MB usable)
Maximum RAM: 4.00 GB PC2-5300 DDR2 SDRAM (3952 MB usable)
Pros: Better graphics, potentially faster WLAN support, improved speed, conservative energy usage
Cons: Poor graphics in Windows, game support on both platforms limited to casual titles (many FPS/RTS/MMO games not supported)
MacBook Pro
The 3G Pro underwent a massive interior overhaul in June 2007, sporting NVIDIA GeForce 8600M GT graphics and—for the first time in an Apple portable—an option to build a Core2 Extreme into the unit at 2.6 GHz. These were the first portables to carry 802.11n as a standard option, as well as the first Apple portables touse an LED-backlit display. The 3G Pro also meets or exceeds all Windows Vista operating requirements, and was one of the best performing computers to run Vista, according to PC World.
Unfortunately for longtime notebook users, the 3G lines of the MacBook Pro also mark some “lasts”. The line of 3G Pros was the last line of portables to have officially shipped with Tiger, the last portables to includean Apple Remote as standard equipment, and, perhaps more notably, the last tobear a traditional numeric keypad.
Case type: Anodized aluminum composite with plastic edging.
Chipset: Intel GM965
Standard RAM: 2 GB
Maximum RAM: 4.00 GB PC2-5300 DDR2 SDRAM
Pros: Significantly improved graphics, greater energy efficiency over 2G units due to chipset and display upgrades, fastest unit of its time for current OSes, solid all-around performance, potentially faster WLAN support.
Cons: Not quite “future-proof”
Fourth generation (4G)
The “Early 2008” portables were met with fervent anticipation, as Apple hinted about “something in the air” at what would be CEO Steve Jobs’ final Macworld Expo address. Notebooks were all the rage, as was the upcoming iPhone software upgrade that gave rise to application development and the App Store. Exciting news indeed, it was. Yet, as was the norm in Jobsian monologues, he had “one more thing” to show off. Inter-office memos? Nope, but it did arrive in the classic manila envelope used for such. It was the first-generation MacBook Air, partof a 4G lineup that saw revamped Core2 CPUs ranging from 1.6 GHz all the way upt o 2.6 GHz depending on model and build options.
The new CPUs were based on Intel’s latest “Penryn” cores, some of which received a drop in L2 cache versus the “Merom” cores used in 2G and 3G units. However, the drop in cache did little to impact performance; the new CPUs were actually faster by a slight margin at the same speeds as prior Core2’s, per Macworld’s bench scores. As there were few changes in case designapart from removing the keypad from the MacBook Pro, only software can separate a 4G unit from a 3G unit.
The 4G units, and all units following, officially support x64-native Windows via Boot Camp 2.1 as included on their Install Discs, or ondiscs with future versions of OS X and Boot Camp.
MacBook
The 4G MacBook saw the processor upgrade and little else,but the bump was likely enough to convince any but the hard-core 12” PowerBookenthusiasts to cross over to Intel. Because it’s still based on the Santa Rosa (GM965) platform, the 20-pluspercentage point improvements touted by tech-savvy bloggers and enthusiastsites are never realized. Rather, some sources have documented a roughimprovement of between three percent and ten percent over the 3G units.
Sadly for some, this model is the last MacBook to bear anysize and speed of FireWire port.
Case type: Solid white or black polycarbonate shell (as of late 2008, white only)
Chipset: Intel GM965
Standard RAM: 2 GB (1904 MB usable)
Maximum RAM: 4.00 GB PC2-5300 DDR2 SDRAM (3952 MB usable)
Pros: Still a solid machine for light work, cheap, fast for its price
Cons: It’s the only cheap way to make your FireWire gear work
MacBook Air
The new kid on the block this go-around;the MacBook Air is Apple’s first sub-notebook since the PowerBook Duo of the early 1990’s. Classified as a “thin and light”, the Air is a very strikingdefinition of that term. At three pounds weight and 0.16” to 0.76” thickness, and with logic circuitry the length of a standard No. 2 pencil, Apple could crow about making “the world’s thinnest notebook” and still pack more punch into a space of 14 inches at a time when other sub-note vendors were still trying to shrink their wares. These vendors, according to Jobs, started shrinking items that shouldn’t be shrunk. Where most sub-notes had 11” or 12” screens, for example, the Air packed in a 13-incher; and when a keyboard was needed for the Air, Apple went with a full-size board identical to the then one-and-a-half-year-old MacBook design, complete with inset keys. From the MacBook Pro, the Air gained an aluminum finish as well as a backlit keyboard. On its own, the Air introduced solid-state storage (colloquially “flash drives”) as hard drives for the Mac. However, this option added $1,000 to the Air’s asking price and dropped its already limited storage capacity from80 GB to 64 GB. To add insult to injuryin some minds, the Air also dropped common expansion options and an internal optical drive to acquire its legendary dimensions. Left after shrinkage: a single USB port, an audio jack, and a “micro-DVI” video port. Despite these sacrifices, the 1G MacBook Air still outclasses other sub-notes where it counts because its chipset is the same GM965 used in the 3G and 4G MacBook offerings in addition to having the fastest low-voltage CPU’s of the day in custom quarter-sized packages. Its performance in comparison to full-featured notebooks is lower by way of processor speed being lower, and yet normal for a portable of its class.
Case type: Anodized aluminum
Chipset: Intel GM965
Standard RAM: 2 GB onboard (1904 MB usable)
Pros: Size and weight offer maximumportability, big screen and keyboard offer comfort for travelers, multi-gesturetrackpad has large surface for easy usability, and price is on par for class.
Cons: Limited expansion options, limited storage, and service-removable battery ,costly add-ons required for use in environments where WLAN isn’t an option, not well suited to Windows variants beyond XP.
MacBook Pro
Not much new here from the 3G lines, save for the absentkeypad. Base specs were upped by small increments, and dedicated VRAM doubled for all models. Nonetheless, the 4G Pro can make a capable,if not solid gaming unit (as if the 3G unit wasn’t competent in its own right). Like the 3G unit, it is also well suited to Vista and its 64-bit variant, and it can easily run Windows 7 in its many forms as well.
Case type: Anodized aluminum composite with plastic edging.
Chipset: Intel GM965
Standard RAM: 2 GB
Maximum RAM: 4.00 GB PC2-5300 DDR2 SDRAM
Pros: Robust graphics, flexible options,and multi-gesture trackpad
Cons: What’s not to like? If you liveor die crunching numbers, it’s tougher, but doable.
Fifth generation (5G)
As is done in every odd generation, Apple reworked the entire line of notebooks from within for the “Late 2008/Early 2009” cycle. In addition, Apple was hard at work on atotally new and totally trend-setting casing process for its portables. The result: an extreme makeover not seen in Apple’s portable lines since the 68K-to-PowerPC transitions of the early 1990’s. To rework the interior of the MacBook family, Apple went to NVIDIA—not Intel—for a high-performance logicsolution to be used in notebooks. NVIDIAwas working on a desktop chipset at the time; but if Steve Jobs’ statement at Apple’s October ‘08 notebook event is to be believed, Apple designers asked NVIDIA to make it mobile, and the company delivered an MCP logic set dubbed“GeForce 9400M” unto Apple. All linesthus benefited from markedly faster graphics and the adoption of ultra-fas tDDR3 memory. Here, the 5G MacBook and 2G MacBook Air became passable all-around units, with the 5G MacBook Pro sportingdynamically switchable graphics engines.
For the exterior makeover, Apple Senior Designer Jon Iverevealed that Apple’s latest process created a “unibody” enclosure that waslighter and required fewer parts to produce, for it was milled entirely fromone sheet of aluminum. To complete themakeover, Apple drew on its experience with the Aluminum line of iMac desktopsand fused all-glass displays into the new assemblies.
For some models, the fifth generation held well into 2010,and so received only incremental upgrades to the CPU, GPU, and system RAM
All models from this generation, save for the whiteMacBook, include a button-less, customizable multi-gesture trackpad.
MacBook and MacBookPro (15”)
Because the two lines had converged in this iteration, only subtle visual differences kept them apart. Both lines dropped the FireWire 400 port and exchanged their respectivevideo outputs for a common Mini DisplayPort, based on an emerging standard. The loss of certain status quofeatures on both lines (FW400 on theMacBook, traditional keyboard on the Pro) drew some whining in certain circles,but such things happen when Apple does this sort of retooling.
With the 5G notebooks, Apple further blurred the line thatonce separated MacBook from MacBook Pro, allowing the former a backlit keyboardin its fullest build. Apple hoped that thiswould swing “fence people” toward the MacBook instead of a low-cost Windows PC since these are folks that would be forced to spend $2,000 on a MacBook Probecause they want to play games in either Mac OS or Windows, casually orotherwise.
Case type: Anodized aluminum unibody
Chipset: NVIDIA GeForce 9400M MCP (withGeForce 9600M GT GPU in Pro models)
Standard RAM: 2 GB (1792 MB usable)
Maximum RAM: 8.00 GB PC3-8500 DDR3 SDRAM( 7936 MB usable)
Pros: Fast graphics, lighter, moredurable, energy efficient, hard drive is user-serviceable, wealth of optionsavailable
Cons: Changes in port makeup require conversion adapters; may frustrate some
MacBook Pro (17”)
At MacWorld Expo ’09, Apple SeniorVice-President Phil Schiller spent more than 90 minutes touting the company’slatest software offerings. In typical Apple style, however, Schiller couldn’t let Apple make what would be its finalcurtain call without a fantastic final act. The 5G-notebook lineup would be rounded out with a stunning revision to one of Apple’s crown jewels: the 17-inch MacBook Pro. Though it’s fundamentally similar to its smaller siblings and received the same makeover from its 4G incarnation that the others received, its battery puts it in a class of its own; Apple claimed not only that the battery will last an unheard-of 8 hours, but also that it would continue to function at nearly 100% potential after 300charge cycles and drop to 80% potential after 1000 cycles, thereby lastingthree times longer than most conventional notebook batteries, including itsown. The reason for this is thebattery’s adaptive charging circuitry, which requests that charge be directedonly to the cells that require it instead of the system charging the battery uniformly across all cells. Real world testing of Apple’s claims yielded figures closer to 5 hours. Still, the fact that the battery is fixed inplace seemed irrelevant. Fixed batteries have been a source of worry for many gadget lovers since the original iPoddebuted in 2001.
Nonetheless, Apple’s flagship retained manyof thee same advantages and disadvantages of its 5G fellows, and yet it remaineda solid machine for those fortunate enough to afford its nearly $3,000 base sticker price. Build-to-order modelsnearly eclipsed the 3 GHz mark—but as Don Adams would have said, missed it by that much.
Case type: Anodized aluminum unibody
Chipset: NVIDIA GeForce 9400M MCP with GeForce 9600M GT GPU
Standard RAM: 2 GB (1792 MB usable)
Maximum RAM: 8.00 GB PC3-8500 DDR3 SDRAM (7936 MB usable)
Pros: Powerful, lighter, more durable,energy efficient, hard drive is user-serviceable, wealth of options available
Cons: Changes in port makeup require conversion adapters; may frustrate some ,expensive entry price, fixed battery
MacBook Air (Second Generation and Third Generation)
How do you improve on the world’s most eye-catching notebook? Apparently, you improve uponit from within, as CEO Jobs outlined during the October event introducing the5G-notebook architecture. Like itsfull-sized siblings, the 2G Air ships with an NVIDIA 9400M MCP and 2 GB of fast DDR3 RAM onboard even as the ultra-low voltage Core2 CPU at its heart has seenonly miniscule improvements in overall clock speed. Hard drive options have seen more modest gains, with the standard drive adding 50% more space than its predecessor and the SSD option doubling to 128 GB. With these adjustments, the Air becomes more palatable to travelers willing toaccept certain tradeoffs in exchange for size and weight. For Windows users under Boot Camp, the Air also becomes a more capable, if still underpowered, Vista unit, albeit one that won’t gain much from an x64-based variant thereof.
Case type: Anodized aluminum unibody
Chipset: NVIDIA GeForce 9400M MCP
Standard RAM: 2 GB onboard (1792 MB usable)
Pros: Size and weight offer maximumportability, big screen and keyboard offer comfort for travelers, multi-gesturetrack pad has large surface for easy usability, and price is on par for class,better storage options than previous model.
Cons: No change in onboard RAM to offset new hardware overhead, add-ons still required where WLAN isn’t available, adapter required for new Mini DisplayPort with most displays
MacBook (’09 White)
A surprise refresh in early 2009 brought an entry-level MacBook under $1,000 with most of the 5G features above. To keep it that affordable, Apple ended up blending a third-gen polycarbonate MacBook exterior with a modified 5G-logicassembly. Users of this model got the same fast graphics engine as the one in the mainstream aluminum MacBooks, all the while keeping the single and now scarce FW400 port; but they also gave up niceties such as the multitouch track pad and the slightly quicker DDR3 RAM. Nonetheless, this 5G model was mostlikely aimed at those looking to start with a Mac and get a full-fledged computer.
Case type: Polycarbonate unibody shell
Chipset: NVIDIA GeForce 9400M MCP
Standard RAM: 2 GB (1792 MB usable)
Maximum RAM: 4 GB (3840 MB usable)
Pros: Solid construction, cheaper than prior models, few if any changes from previous model
Cons: Limited trackpad motion support, RAM capped at 4 GB, looks less classy
Sixth generation (6G)
Perhaps the only generation not to offer a significant step up from the previous one, the sixth generation opened with a minor redesign of the white MacBook, which at long last had caught up with the earliest 5G models and therefore offered a better value than its previousmodel. MacBook Airs also see but a minorspeed bump. True improvement is not achieved until the arrival of the first mobile processors to use the emerging “Nehalem”microarchitecture and to see the return of multithreading support. The processor’s redesign also affords the ability to shut down inactive processor cores whilst boosting the clock speed of those that remain active. Unfortunately, MacBook Pros are the only models to receive this welcome upgrade, even if it only comes in a dual-core package to start with. All other models run on the last knownreleases of the “Penryn” core—a harbinger of things to come, maybe?
MacBook
From Mid 2009 onward, MacBooks continued to shadow their upper-crust siblings, but in the process, they ultimately catch up—to 2008’s lineup. It’s from here that these modelstake a multitouch glass-backed trackpad, a fixed battery, and the Mini DisplayPort monitor connection. A remolded unibody design gives this model a curved front. FireWire finally drops, as does the IR receiver; Apple found that many consumers buying the MacBook just didn’t care for either add-on. Still, subtle bumpsin CPU speed and battery life may have been enough to justify an upgrade from previous generation models.
Case type: Polycarbonate unibody shell
Chipset: NVIDIA GeForce 9400M MCP
Standard RAM: 2 GB (1792 MB usable)
Maximum RAM: 4 GB (3840 MB usable)
Pros: Long battery life, sleeker and slimmer design,slightly lighter
Cons: Almost no change from 5G setup; ports dropped
MacBook Pro (15” and17”)
As mentioned above, the 6G Pro offered little in the way of improvements over the 5G lineup—or so it might seem at first glance. Externally, they appear very much like the 5Gmodels, except that Apple has added an SD card slot to the port array—a big upgrade for camera buffs whom usually resorted to carrying cheap and oft-clunky card readers to dangle from a USB port.
Internally, these two flagship units make several changes to accommodate the Intel “Nehalem” architecture mentioned above. No longer could a third-party chipset be used—the direct result of a protracted battle between Intel and NVIDIA over the terms of the deal that allowed the Core2 to run on a non-Intel logic set. In its place, Intel supplied the “Arrandale” Core i-series multipurpose processors along with the then-new 5 series logic sets. Arrandale brought with it a completely new bus known as QuickPath Interconnect, which in theory was much improved over the traditional front-side bus. Also making their debut were Turbo Boost, which shut down one core and turned up the other based on demand, and the Intel HD Graphics core, a welcome boost over previous Intel offerings that for their part lacked muscle; this new engine could render 720p HD where 2007’s X3100 had to feign it. Last but certainly not least, Hyper Threading Technology, absent since the last of the Pentium 4 600 series CPU’s were cas tin 2006, returns to little fanfare but grants users twice the effective coresduring heavy workload.
Flash storage, introduced on MacBook Airs, makes its way into the mainstream lines with this generation and all that will follow it, though the drives’ expense and potential loss of storage space were not always justifiable, even though flash storage delivers on the promise of improved read/write access speeds.
Despite these huge gains, users anticipating quad-core chips on Macs when high-end Windows notebooks already had such were at the very least disappointed
For the discrete graphics engine, Apple again turned to NVIDIA for its 300-series chips, these being significantly more powerful than the 9-series previously used. Video RAM remained unchanged.
Case type: Anodized aluminum unibody
Chipset: Intel 5 Series/HD Graphics with NVIDIA GT 330M
Standard RAM: 4 GB (3840 MB usable inlow-energy modes)
Maximum RAM: 8.00 GB PC3-8500 DDR3 SDRAM (7936 MB usable in low-energy modes)
Pros: Big lift from i-Series CPU’s, SD cards now usablewithout extra hardware, more starting RAM, SSD options for better performance
Cons: Low-energy modes use a graphics engine that is a drag on gaming for some (per user reports), still dual-core.
Seventh generation (7G)
There may be some discussion as to whether a seventh generation of Mac portables exists, or whether this line should be part of the sixth generation instead. Apple’s internal naming schemes for the mainstream models did indeed point to a seventh generation, so on that basis, here’s a definition: Seventh-gen models were, as the sixth-gen models, a mild refresh. This time, though, the refresh targeted only those models not receivingthe Arrandale i-Series upgrade. All models received the final upgrade of the Penryn Core2’s, as well as replacing NVIDIA’s 9400M MCP with a more robust version in the 320M.
With Windows XP in decline from 2009’s release of Windows 7, this became the last iteration of Mac portables to run the nearly-decade-old platform. Vista, too, would meet its end here, though Microsoft still considers it in mainstream support untilmid-2012. Perhaps Apple wished to streamline their Windows support to a single version—or perhaps it realized what so many others outside of itself knew from experience: Vista was a disaster, and it was best left to rot with its distant ancestor, Windows Me, inthe depths of history’s sewers.
MacBook
The trusty steed of many a cheapskate since its 2006 intro received what would be its last upgrade ever in mid 2010. The Penryn processor gets a slight bump from 2.1 GHz to 2.4 GHz, and NVIDIA 320M graphics round out the package. Otherwise, there’s not much new, for its reign as King of Value would quickly come to a close.
Case type: Polycarbonate unibody shell
Chipset: NVIDIA GeForce 320M MCP
Standard RAM: 2 GB (1792 MB usable)
Maximum RAM: 4 GB (3840 MB usable)
Pros: Modest gains for CPU and GPU—but that’s it
Cons: Still cheap looking with a plastic shell—and you paid WHAT?
MacBook Pro (13”)
Now firmly rebranded as a Pro model, Apple’s 13” aluminum notebook was poised to gain clout with “prosumers” and other types that loved the aluminum look but did not want to pay extra for the new CPU’s of the 15” and 17” models. Still, these units made big gains from the new NVIDIA MCP and Penryn chips up to 2.66 GHz. All in all, this seemed a very well-balanced unit for one a full generation behind its peers, and one that was well worth its $1,200 entry fee
Case type: Anodized aluminum unibody
Chipset: NVIDIA GeForce 320M MCP
Standard RAM: 4 GB (3840 MB usable)
Maximum RAM: 8.00 GB PC3-8500 DDR3 SDRAM (7936 MB usable)
Pros: Full featured for the size, hits a“sweet spot” for the price
Cons: Aging architecture now at limit, no i-Series chips to be found
MacBook Air (Fourth Generation)
The head-turning Air gets a late 2010 all-around makeoverwhile expanding the family of portables to include Apple’s smallest notebook since the 12” PowerBook made a splash in 2003. Even at the new 11.6” size, the Air gets a slightly thicker body than its previous two models. The extra thickness isn’t enough to keep it from being the thinnest, but it is enough to add a much-requested second USB port and to eliminate the clumsy door covering the initial USB port and the video port in addition to exposing the MagSafe connector, making the once-awkward connection more accessible. This also gives it a more rectangular profile in line with Apple’s other models.
The upgraded 13” model doubles onboard flash storage andadds the SD card slot from the MacBook Pros.
Both models now feature factory upgrades to storage andRAM—up to 256 GB and 4GB respectively-- as well as new options from theultra-low-voltage Penryn Core2’s. Bothmodels also benefitted from NVIDIA’s 320M MCP Starting at 1.4 GHz with 64 GB ofstorage and 2 GB RAM for $999, the MacBook Air slowly began to earn its place as the value leader, costing just as much as the venerable white MacBook. Even so, with so many options for this model,there was something to fit every budget.
These models are the first to carry a specific OS requirement when running Boot Camp, despite running Snow Leopard as previous models can. Windows 7 is a must, though one would be hard-pressed trying to squeeze it into a minimally configured 11” unit
Case type: Anodized aluminum unibody
Chipset: NVIDIA GeForce 320M MCP
Standard RAM: 2 GB (1792 MB usable)
Maximum RAM: 4 GB (3840 MB usable)
Pros: Still thin and light, wealth of options available,extra USB port, ports much more accessible
Cons: Options fixed at time of order, Boot Camp needs toospecific for some users
What About Sandy Bridge?
As of February 2011, Apple was one of the first manufacturers to introduce Intel’s Sandy Bridge platform to the world, ushering in the eighth and current generation of portable Macs. With this generation, quad-core, eight-thread i-Series CPU’s are a staple of the 15” and 17” high end, while dual-core ,quad-thread models still populate the lower end. Nonetheless, all models now benefit from the same new technology with none fully ahead of or behind the others.
All models also feature a breakthrough in peripheralconnectivity that combines bandwidths of both PCI Express and DisplayPort intoa bus markedly faster than any bus presently in use. Christened “Thunderbolt”, the new interface offers enormous potential with its theoretical 10 gigabit-per-second bandwidth. However, devices using Thunderbolt are only beginning to emerge on the market,thus it is still too early to offer any concrete opinion regarding thistechnology.
As these models are currently on sale (and have recentlybeen updated) at the Apple Store and Apple Authorized Resellers worldwide, to proffer any opinion of current models defeats the purpose of this, anhistorical document of Mac portable evolution.
Conclusion and Final Thoughts
To have witnessed and tracked the evolution of Apple’snotebook lines from 2006 to the present is no small feat. One could say that doing so is in fact opening a window on the history of Apple itself, for it is in Apple’s notebooks that we have seen the greatest innovations both from the company and in computing itself. From their inceptionin 2006, Apple’s Intel notebooks have evolved into some of the best and mostreliable notebooks on the market today. To be able to run Windows as well asthe Mac OS only solidifies that position.
Yet, with each stage of their evolution, the MacBook, MacBookPro and MacBook Air, while they have made significant forward progress, havehad to sacrifice features that some users find essential. Still, while the complaints roll in with each generation of notebooks, time must march on. Apple is a computer company after all, and must continually update its wares if it is to remain in its current position near the top of the industryat large.
The stark realities of Apple’s business, however, should never be used as an excuse to buy the latest and greatest hardware even if yours seems less capable than someone else’s. Holding onto older Apple hardware may actually put you at an advantage, since you may still be able to work with hardware that newer models don’tsupport. This is one of many reasons Macs tend to stick around longer than most Windows PCs.
I certainly hope you have enjoyed this look back at Apple’s Intel notebook lines. As a proudmember of the Mac community for almost eight years and a volunteer whose role connects him to computing past, I find this knowledge of the past fascinating; and yet it is vital to maintain such a background, as it can give us as users an idea of where the industry will be in the months and years to come.Due to a copy/paste glitch, some necessary spaces have inadvertently been removed.

Appending Xpath Value to a variable in For Each loop
So I am iterating thru an XML File collection inside a ForEach container. I have an XML Task within this loop of type Xpath.
The Xpath expression on each file evaluates to a value which I want to append as I keep iterating.
How do I go about doing this?? I tried something like User::CheckSum =+ User::CheckSum but it gives and error and I am not sure on which property should it be applied to.
Please understand that it is not one file with multiple nodes but multiple XML files in my scenario.
Any help is much appreciated
SMI do not think the variable's value gets preserved between hops, anyways, it does not look like a valid approach.
Use the XMLFile Source in the ForEach Loop and capture the needed value into a package variable that you can keep appending to say in a Script Task.

Syntax and format of a IF statement in formula XPath in a InfoPath field
Good day
I needed assistance with IF statement syntax in a InfoPath field formula.
If Field_1 = null
concat(substring-before(txtComponentNo1, "."), ".", substring-before(field17, "."), ".", substring-after(field17, "."))
Else
concat(substring-before(txtComponentNo1, "."), ".", substring-before(field17, "."), ".", substring-after(field17, ".")+1)
or in Advance XPath
If Field_1 = null
concat(substring-before(../../../my:grpComponent_1/my:grpComponent1/my:txtComponentNo1, "."), ".", substring-before(../../my:field17, "."), ".", substring-after(../../my:field17, "."))
Else
concat(substring-before(../../../my:grpComponent_1/my:grpComponent1/my:txtComponentNo1, "."), ".", substring-before(../../my:field17, "."), ".", substring-after(../../my:field17, ".") + 1)

Help with if statement in XPATH
Hi,
I´m using XPath to return a value for a conditional Branch in OSB, I understand that it is supposed to work with standard XPath so I post this question in this forum:
What I want to do should be simple but have not worked for me, I want to do an IF statement and to return one value in the then part or another value in else.
if the statement is acomplished I want tu return just a string and if it does not acomplish then in the else return a value from an Xpath expresion:
here something similar of what I´m trying:
if (./imp:iniciarCambio/cambios/bea:ListaDeCambios/bea:Cambio/bea:campoNombre/text() = "Name")
then M6yBilling
else ./imp:iniciarCambio/cambios/bea:companiaTipo/text()
The part that is not working is where I want to return M6yBilling if the statement acomplishes, I have tried "M6yBilling" also 'M6yBilling' and fn:string(M6yBilling) but none is working at all.
Any ideas?
Kind Regards,

Xpath field details not getting displayed
Hi all,
I am working on a idoc to file scenario, where I want to refer the receiver to be determined based upon certain condition or values that get populated for a particular field (using receiver determination). But the problem is that when I click on the condition tab on receiver determination I get a warning "Problem loading schema description"
with message as
"Message interface does not exist in any software components installed on this business system"
But since it is an Idoc at the source we dont have any msg interfaces, further if i neglect this warning message and go further, I am not getting the fields or details of the Idoc structure getting displayed in the xpath.
But the same when I use for a file scenario(file as sender) I get the details of the context object if any.. Let me know how to resolve this..
Thanks in advance
Regards,
NithiyanandamHi,
Yes you coudl add the missing Software component as per below steps
Even if you open Business system in Integration Directory, at last tab "Other Attributes" --> you will find the list of software components.
Press the tab Third Party service to verify the list against SLD.
If its not avaialbel in SLD
1. Goto System Landscape Directory
2. select Business Landscape and slect the apporpriate Business system and open it. (Click the name of BS)
3. There you will get the list of Software components added in it.
4. Verify the technical system name.
5. Also verify if same technical system name is used after importing the software component in Integration Repository (IR).
Goto IR -- > Explore the SCV -->Double click on name of software component version -->Check Interface Import as Import of RFC and have the same details in Connection data as per technical system
If everything is setup just refresh the SLD_CACH and import the scenario once again in Integration Directoy and process it.
You will see the IDOC in Business system.
Thanks

Creating a portable backup drive that's encrypted
I've been considering an off-site backup solution like Carbonite to protect my files, particularly now almost all of my photos etc are digital and on my mac. I use Time Machine to an external desktop drive for day to day backups, but want to protect against loss from theft or fire.
I'm not keen on paying annually for something like Carbonite, and instead have been thinking of a small pocket-size portable hard drive that I can take with me regularly if I'm away from home. However, I'm also conscious of losing the hard drive and not wanting anyone finding it to have access to the files on there. Is there an easy way, without buying any new software, of making a portable external hard drive encrypted, so that I can regularly backup files to it, but if it gets lost, others can't access the files on there?
CheersUse Disk Utility to create an encrypted sparse bundle disk image. Store the .sparsebundle file on your external drive. Mount the disk image by double clicking it. Copy your data to the mounted virtual drive. Eject the virtual drive when done. You can also store the disk image password in your keychain so that you do not need to re-enter it when you mount the image on your own Mac.
If your drive is lost, the contents will only be retrievable be somebody who knows the disk image password. -
Backup I-Tunes Music to another portable hard drive?
I would like to backup my music to a portable hard drive instead of multiple DVDs within the I-Tunes program. Is there another way to do this?
You can't backup to an externa hard disk in iTunes, but there is nothing to stop you doing it in Windpws Explorer.
Assuming you have a default installation i.e music files in the iTunes Music folder, just close iTunes and copy the iTunes folder to the external disk.
It more convenient to use backsoftware which can backup changes, so after the intial backup, further backs are fast.
There is an article on backup here:

How do I get a portable HD to mount on my MacBook Pro G4?
I recently bought an Iomega eGo USB portable HD, so I could back up my data. The drive is not defective–it works fine on a desktop PC. I plugged it into my USB ports (I had to use both ports, with one extension cable–my ports are on opposite ends of my keyboard) to get enough power. I can hear the drive spinning, but the icon does not show up on the screen. The online manual says to reformat the HD, but I can't do that if the computer can't see it.
Is the solution to buy an auxiliary power source that uses AC power in addition to the USB ports? I can't get the answer at Iomega, because the portable HD was bought on eBay, and Iomega does not cover items bought on an auction site. They don't recognize them as authorized resellers. I found this out just yesterday, as this is not mentioned in any of their literature.Okay i looked them up and YES they are compatible with macs. if it's formatted for windows then no it will not show up on the mac, you need to repartition it on windows or try and see if you can pick it up in Disk Utility on osX. The following link is for this HD but talking about a mac PowerBook, it should be the same for you even if you are using the Intel macs. http://www.mac-forums.com/forums/other-hardware-peripherals/146258-iomega-portab le-hard-drive-not-mounting.html

Using iWork, iCloud for ultra-portable presentations
I am considering buying a refurbished iPod Touch or iPad Mini, and I wanted to discuss how to apply iWork for iOS in concert with iWork 2009 for Mac.To wit:
As you can see from the listings below, I have access to useful hardware and software. I am writing this to seek advice on how to leverage these tools to give business (and personal) presentations while I'm on-the-road and may (or may not) be carrying hardware with me. If I'm forced to travel light, I was wondering if simply taking a thumb drive and/or using my iCloud account may be enough.
I work for a small construction business that does projects in eight surrounding counties. I work as a "Producer", which means I'm both an office manager (writing up contracts and job estimates, arranging business with customers, contractors and suppliers over-the-phone) and a project manager (working with those same business contacts in-person on remote project sites). I am also applying for work outside of our business, and want to be able to use visual aids if/when necessary to illustrate what I do during an interview.
I recently started taking a Lynda.com course on "Setting Up Your Mobile Office to Work from Anywhere", and it got me to thinking about how I could use iCloud and Apple's iWork apps to create business presentations that could be played in a variety of portable scenarios. My goal is to be able to travel light and still be able to make presentations to individuals or groups.
MY CURRENT PERSONAL/BUSINESS HARDWARE & SOFTWARE
iMac 13,1 : late-2012 slimline model, 2.9 GHz Core i5 processor, 8 GB RAM, 1 TB hard disk, USB SuperDrive
MacOS X 10.8 Mountain Lion
iLife 2011 (including iPhoto 9.2.3)
iWork 2009 (including Keynote 5.3, Pages 4.3, and Numbers 2.3)
Microsoft Office 2011: Mac
Final Cut Studio 3, including Final Cut Pro 7
Adobe Photoshop Elements 8
iCloud account, free-tier service
DSL high-speed connection to internet
Have been shooting digital photos since November, 2001; manages iPhoto library of over 52,000 images
OTHER HARDWARE AVAILABLE
white MacBook 2006 vintage, 1.83 GHz Intel processor, 2 GB RAM, 160 GB hard disk, SuperDrive, MacOS 10.6.8, iLife 2011, iWork 2009, Microsoft Office 2011 (MacBook is not my machine; used by someone else in my office. This computer has battery issues; it must be plugged into AC power.)
Epson EX7200 projector, with USB thumb-drive port (for JPEG presentations), VGA port, and HDMI port.
Scenario #1: If I prepared a Keynote presentation on my iMac and transferred it via WiFi or thumb drive to the old MacBook, do I need to copy just a single Keynote file over and that's it? No attached files or folders with files in them?
Scenario #2: I have successfully, in the past, used the Epson projector and a thumb drive loaded with photos and also a USB camera card reader with an SD card attached to show simple JPEG photo slideshows. If I wanted to just use the Epson's USB port to show Keynote slideshows, they would have to be stored in folders as JPEG files. How easy is this to prepare with Keynote? Are there any pointers available on designing a useful workflow for preparing such slideshows without a lot of fuss?
Scenario #3: Forget the projector; too much bulk. If I had just a small iOS device like an iPod touch, and I wanted to plug into someone else's projector (or if I wanted to just show a slideshow of images to one person with no projector) what do I need to be prepared for, hardware-wise? What do I need to do with Keynote, both on the iMac for production and on the iOS device to make it look right?
Scenario #4: Let's say I'm going to carry everything on a USB thumb drive as a backup. What is the best way to set it up to play on someone else's hardware? (I assume three tiers of compatibility: I do network with Mac/iOS users, so Tier #1 would be Apple compatibility with Keynote. Tier #2 would be general compatibility with Microsoft Office 2003/4 for pre-XML file formats. I guess that Tier #3 would be general-purpose PDF files, or maybe the JPEG file approach with thumb drive ports on projectors.) If I'm doing Tier #1 and I'm plugging my thumb drive into someone else's MacBook, are there any pointers to avoid font conflicts or other issues? If I'm doing Tier #1 and I'm borrowing someone else's iPad to show a slideshow, how do I get the files off of a thumb drive to show on the iPad?
Scenario #5: ** iCloud ** Let's say I'm traveling VERY light, and I want to give a presentation that's stored on my Apple iCloud account. How can I organize files and folders so that Tier #1, #2 and #3 files are available (assuming I have an internet connection) so I can play a presentation off someone else's hardware, be it a tablet or laptop. Is there anything I should know about how to prepare this and how to reliably be able to log-in and access my iCloud files? Are my iWork 2009 apps going to function in preparing and saving presentation files with my iCloud account?
Scenario #6: Scenario #6 is Scenario #5, but substituting another service instead of iCloud, like maybe Google Drive. Is there any way to set up an account with files so I can reliably be able to access said files for a presentation?Just sign into your iCloud account on icloud.com, click the app that you want to use (see below) and it will launch. You don't need to sign into anything but your iCloud account.
