Thanking again for your help
The first hit I got from

f&q=%22java+exercises%22&spell=1]Google when
searching for "java exercises" is this page:http://www.cafeaulait.org/books/jdr/exercises/
The answers to the exercises are also available there.
Of Course it's a matter of personal taste.
However to my mind the best 'exercise' based tutorials are the MageLang
ones you can find on this site , once you figure out how to download them.

How to assign and transform or how to deal with xsd:anyType elements in 10g

Hi,
Any Update on this please...
Hi,
we are using canonical model as part of 10g, here I am not able to assign or tranform elements of type xsd:anyType to/from to other type elements. Solution with an example and quick reply is appreciated.
=========================================
Hi,
By using copy-of xslt construct again input element structure is getting copied into the target mapper file, by using value-of xsl:construct just the value is getting assigned. Can you please elaborate on how to use this xsd:anyType elements in assign and tranform activities, overall how to use these elements in 10g, while implementing the canonical model.
ex:
xsl file: by using value-of
<xsl:template match="/">
<ns1:abstractRef>
<ns1:amount>
<xsl:value-of select="/ns1:BPELProcess1ProcessRequest/ns1:input"/>
</ns1:amount>
</ns1:abstractRef>
</xsl:template>
Result:
<abstract1>
-<abstractRef xmlns:ns1="http://xmlns.oracle.com/BPELProcess1" xmlns="http://sample/test">
<ns1:amount>6556</ns1:amount>
</abstractRef>
</abstract1>
Here amount is of type xsd;anyType which is present in the abstract complexType.
xsl file: by using copy-of:
<xsl:template match="/">
<ns1:abstractRef>
<ns1:amount>
<xsl:copy-of select="/ns1:BPELProcess1ProcessRequest/ns1:input"/>
</ns1:amount>
</ns1:abstractRef>
</xsl:template>
Result:
<abstract1>
-<abstractRef xmlns:ns1="http://xmlns.oracle.com/BPELProcess1" xmlns="http://sample/test">
<ns1:amount>
<ns1:input>6556</ns1:input>
</ns1:amount>
</abstractRef>
</abstract1>
and while using it on assign activity, it is not assigning the input value to the xsd:anyType element, please provide an example on how to do this activity along with tranform.

Solution Database - Maximum number of Problems and Solutions

Hi everyone,
I´m new at CRM and I was wondering if you could help me sharing your knowledge and experience on this.
I completed the SAF and solution database configuration , I was wondering if there´s a maximum number of problems when creating problems and solutions on IS01? Also Can I have 2 or more solution data bases (with different problems and solutions) assigned for a business role?
comments are appreciated
thanks!

Vista "Problem Reports and Solutions" - Compatibility issues?

The Visa +Problem Reports and Solutions control panel+ is reporting three problems which I cannot seem to be able to find a resolution to.
( So far I've just installed Vista 32 business ed. on my iMac 20". Installed bootcamp drivers, updated bootcamp to 2.1 and applied Vista updates.)
*The Problem Reports and Solutions control panel reports the following:*
1. Download and install the driver for Apple performance counter
This problem was caused by Apple performance counter, which was created by Apple Inc..
2. Compatibility issue between Intel 82801GBM (ICH7-M) LPC Interface Controller - 27B9 and Windows. This problem was caused by a compatibility issue between Intel 82801GBM (ICH7-M) LPC Interface Controller - 27B9 and this version of Windows. Intel 82801GBM (ICH7-M) LPC Interface Controller - 27B9 was created by Intel Corporation and is distributed by Apple Inc..
3. Problem caused by Apple Desktop Null Driver.
This problem was caused by a compatibility issue between this version of Windows and Apple Desktop Null Driver. This product is usually distributed by the company that manufactured your device or computer. Note. If you bought Apple Desktop Null Driver from a retailer and installed it yourself, you will need to contact its manufacturer.
Are these genuine, and if so, is there a solution? No solutions are proposed by Vista itself.
Mac OS 10.5.5 , bootcamp 2.1
Message was edited by: noutram

A performance counter is not something that is usually in use by any application except by the developers of the unit itself. nothing to be alarmed about (well, except perhaps that it should have been removed).
A null driver is (as the name indicates) null, there is no functionality assigned with it. MS error message is just brilliant "there is an error in your null driver", like what, there is no functionality in a null driver. So no problems there either.
I got the 2 above error messages on the very first generation 17" MBP for ages and so far not seen any impacts in it for my work.
The Intel issue is interesting, it might be a good idea to see if Intel has an updated driver for the problem.

Assigning existing solution (SDB) to ticket

Hi Colleagues,
I cannot assign an existing solution to a ticket.
We have SAF and TREX woring fine. I can search all our problems and solutions with any problem using "Solution Database" tab in the ticket (CRMD_ORDER transaction).
But if I find a proper solution I cannot assing it to our ticket. It seems that "add to cart" in the hit screen is not activated.
If we create a new solution using action "SLFN0001_ADVANCED_SDB_CREATE", solution is attached to the ticket in "Solution Database" tab.
best regards.

Guys,
Problem and solution are released and compiled into TREX. I can seach sucessfully our problems and solutions.
The problem I have is with trx. CRMD_ORDER in Solution Database tab. I can search for the solution but I cannot attach it to the ticket as a found solution.
If I create a new solution from the action, it gets recorded in this tab, but I cannot assign "existing" solutions to the ticket since the tab is not maintainable.
Take for instance the "SAP Notes" tab. If you search for a note and find a relevant one, you can assing it to the ticket.
¿Can we do the same for "existing"solutions in our own solution database?
Best regards,
Renato

Compilation of Lenovo X120e issues and solutions

Just thought a compilation of issues may be beneficial for folks who own an X120e.
Screen adjusts brightness automatically without user input depending on content on screen:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X100e-screen-brightness-increasing-by-itself/td...
This is caused by Vari-Bright being enabled in the Catalyst Control Center. With this option enabled, the screen will automatically adjust its brightness depending on what is shown on the screen. The display brightness is increased when the screen is predominantly white while the display brightness is decreased when the screen is predominantly dark. An easiest way to see this effect happening is to have two tabs opened in a web browser window. Set one tab to display a website that is mainly filled with white pixels (such as this Lenovo Forum) and another tab to display a website that is mainly filled with dark pixels (such as http://www.krijtenberg.nl/ ). Switch between the two, pausing a few seconds in each tab.
Solution:
Open the Catalyst Control Center and select the PowerPlay option in the Power section. Uncheck the Vari-Bright option (or adjust the slider) and click Apply. Verify that the automatic adjustment is no longer occuring by doing the two tab experiment described above.
Function keys for brightness control not working after waking from sleep / hibernation in some instances:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Funtion-keys-for-brightness-not-working/t...
For my X120e, whenever I have it sleeping or hibernating and change the power source (such as initiating sleep when on power and then waking it up while on battery, or vice versa), the function keys for brightness controls do not work.
Solution:
Restarting the machine will bring back functionality of the brightness control keys...
A way to prevent this from happening in the first place is to wake the X120e in the same power state that the X120e was put to sleep in (wake up from power adapter if slept while connected to power adapter, or wake up from battery if slept while on battery).
All we can do now is wait for Lenovo to come up with a fix on their side of things.
AMD SATA Controller and TRIM for SSD:
The AMD SATA Controller provided by Lenovo does not support passing of TRIM command according to http://www.hardwarecanucks.com/forum/450343-post35.html for SSDs. The Lenovo provided AMD SATA Controller is 1.2.1.197, before the official TRIM support in 1.2.1.263. If you're using a HDD, this is of no concern.
Solution:
In order to have support for passing of TRIM command, one has to update the AMD SATA Controller to any version above 1.2.1.263 ( http://sites.amd.com/us/game/downloads/Pages/integrated_win7-64.aspx#3 for Windows 7 64-bit, for example) or uninstall the AMD SATA Controller to revert back to Microsoft's Standard AHCI 1.0 Serial ATA Controller.
Disclaimer: Since the AMD SATA Controller driver linked is not from Lenovo themselves, I'm sure they won't provide any support if something is to occur so try at your own risk.
As HP79 mentions below, at least according to the update notes, TRIM implementation is implemented for Hudson chipsets as of 1.2.001.263.
Audio Stutter / Slurring occuring during playback of video/audio:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Stuttering-Audio/td-p/389023
This issue can be reproduced (at least on my X120e) by waking the X120e after putting it to sleep. The symptom is the audio repeating a sound over a span of a second or two during playback and is quite noticable.
Solution:
uEFI Bios version 1.11 seems to deal with the audio stuttering issue. So far, results lead to positive outcomes.
Old Solution:
PWMTR64V.DLL that is loaded at Startup seems to be causing this issue. Disabling it from launching when starting up seems to cure the Audio Stutter (even after waking up from sleep which was seen to be a pretty reliable way to get the issue to repro). Start Menu > Launch MSCONFIG from the Search Bar > Select Startup Tab from the System Configuration window > Uncheck Thinkpad Power Manager > Restart.
This does not seem to turn off the power manager application itself so settings in Power Manager can be saved and it seems to still be in effect. However, opening up Power Manager from the notification / taskbar can cause audio stuttering and mouse movement slowdown while it is launching and/or when applying settings. This is only temporary and is gone when Power Manager is closed. (Thanks kns7977 for the find)
Pending to see if those who uninstalled Power Manager are able to turn off the offending startup .dll.
Mouse seems to stutter or stay in place for a moment when moving:
This seems to be caused by the same issue causing the Audio Stutter / Slurring. At least at this time, the cause of the issue and solution seems to be the same.
Emulating Middle Mouse Button with Trackpoint:
One can set up the middle button between the left and right click button for the TrackPoint to act like pressing a middle mouse button on a standard mouse by changing the scrolling type to Smooth instead of the default Standard.
Control Panel > Hardware & Sound > Mouse > UltraNav Tab > Setting for TrackPoint > Setting for Choose Scrolling or Magnifying Glass Function > Smooth.
Trackpad's two finger gesture being hit or miss:
The trackpad's two finger scrolling is very hit and miss.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-Touchpad-issues/td-p/393751
Solution: Turning off Gesture Filtering may alleviate the problem. As mentioned in http://forum.notebookreview.com/lenovo-ibm/561751-x120e-owners-thread-24.html#post7323293, it seems that the Gesture Filtering is counteracting any sort of two finger input.
Get to Mouse Properties by Fn + F8, select Manage Settings. At Mouse Properties, select the UltraNav tab > Settings for TouchPad. Expand the Smart Check Settings, highlight Gesture Filtering, and uncheck the Enable Gesture Filtering box and Apply.
Screen flickers lines:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Flickering/td-p/389523
Had this issue occur on me once, but never seen it happen again. Unsure what caused or cured it.
Solution:
If the flickering is occuring, a restart is all that is needed to alleviate the problem. Haven't tested if hibernation fixes it, but neither sleep nor turning off the screen with the Power Manager dealt with the flickering.
3-Cell Battery mentioned as a 40Wh in the Order Page of Lenovo X120e when it is actually rated as 32Wh according to Power Manager:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-3-cell-40Wh-battery-reported-as-32Wh-by-P...
Yeah...
Solution:
Accept that it's a 32Wh you will get when selecting 3-Cell or go for the 6-Cell if you want more than 32Wh.
2x2 ABGN Driver from Lenovo triggering Error Code 10:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-ABGN-Driver-issue-in-Windows-7-Pro-x64/td...
The Wireless driver from Lenovo's site seems to not work with the 2x2 ABGN wireless when installed on a fresh copy of Windows 7 x64.
Solution:
Not really quite a solution, but one can bypass this by either installing the 32-bit Windows 7 and installing the 32-bit driver, or using the factory recovery disc to install 64 bit windows 7 to have it install drivers that work for x64 windows 7.
X120e bluescreens after installing LAN Realtek 7.26.902.2010 drivers from Lenovo's Driver download site.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-bluescreen-when-installing-lan-drivers/td...
The drivers doesn't seem to work and it causes a bluescreen on fresh installed Windows 7 x64.
Solution:
As Clicq suggests, Realtek's own drivers from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTy... seems to deal with the issue.
Screen quality on the X120e:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-poor-LCD-quality-viewing-angles/td-p/3945...
The quality of the screen on an X120e is below expectations.
This is common with low-quality TN panels not helped by glossy displays. My personal X120e screen likes to bleed certain colors of red.
Solution (not really):
One can use the Windows 7 built-in color calibration tool to adjust the colors to make it more tolerable. Adjusting your own viewing angle in relation to the screen might deal with some color issues (hard to figure out what's the correct viewing angle because of TN panel's small range of optimal viewing angles). Also, changing the refresh rate to 60Hz may deal with some headaches due to the screen (as it did for me).
HDMI Overscan to HDTV issue:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/HDMI-overscan-to-HDTV-issue-on-x120e/m-p/395335
There is a black border when outputting to HDTV through HDMI.
Solution:
AMD's CCC by default sets a specific value for overscan / underscan. One can http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Output-to-TV-via-HDMI-port-black-border-on-the-... while the device is connected via HDMI (the option is hidden if the HDMI port is not used) and adjust the slider to an acceptable value.
Skype asserts after 10-20 seconds of video chat:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Skype-quits-after-10-20-seconds-of-video/...
When doing a video chat, the video feed will freeze and then skype will crash to desktop.
Solution:
Version 5.3 of Skype seems to be the culprit. Until Skype itself is fixed, one can use Skype 5.2.60.113 from http://www.filehippo.com/download_skype/changelog/9465/ to bypass this issue. Just reject any offer to update to 5.3 after installing 5.2, for now.
If there is anything I missed, please respond and I'll update this post with new information. These are the ones that I have encountered so far with my Lenovo X120e. Don't get me wrong, I like my X120e... it's just been a "learning" experience lol
For a compilation of most X120e issues:

My Iphone/ Ipod touch 4th gen WiFi problems and solution

Just wanted to let people know the problems that I had with my 4th gen Ipod touch and Iphone 4 WiFi connections (and my solution).
I was having consistent problems with my WiFi connection at home - my devices were connecting fine to the router and apparently the signal was full strength; however, nothing was working properly (internet, itunes, app store). To be specific the devices would work for 5-10 minutes but then the connection would start to falter. My other wireless devices were working fine (HTC Hero, laptops etc.) - just the ipod and iphone seemed to suffer from this signal problem (although the router was always apparently connected).
Obviously, I read countless forums to try and diagnose the problem. There seemed to be a litany of possible causes and I tried the following to resolve the issue:
- updated router (Netgear WGR614 v6) firmware
- rotated wireless encryption (WEP/WAP/nothing)
- changed router channel
- reset router power
- reset network settings on Apple devices
- changed g and b settings on router
Nothing seemed to work so I began to question the hardware i.e. the router (which I knew was working from my other devices) and the iphone/ipod.
I tested my iphone and ipod on other wireless networks (McDonalds in the UK has free WiFi) and found that, in contrast, they worked fine on other networks. I had read a few posts from people saying that my router was perhaps too old. So as a last resort I bought myself a new router (Netgear WNR2000 v2). I was loathe to do this earlier in case it didn't work, since reasonable spec routers are £50
Anyway it worked ... straight away. I have tested the new connection at home using this SpeedTest app. D/load = 9.01 Mbps, U/load = 0.46 Mbps, Ping 65ms. The router is using the full encryption (WAP2 something ...) and N connection.
As you can probably tell I'm no WiFi expert - I just wanted to post this in case people are having similar issues with older routers. I wasn't able to find any definitive advice and solutions from other users so I though I'd contribute here, which I guess is the first port of call for new Apple users, like me
I bought the new router 10 days ago and have been enjoying my full speed connection ever since - touch wood. Hope this helps.

Sounds like an intermittent contact problem some where eon the logic board. Hard to trace down and fix

Built-in iSight cameras
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
If your built-in iSight camera is still not behaving correctly after trying all these steps, you may need to contact Apple or an Apple-Authorized Service Provider for service.

Install both SAP ECC 6.0 EHP 4 and Solution Manager in C drive

Hi, SDN fellows.
I just want to confirm this.
I am trying to install SAP ECC 6.0 EHP 4 and Solution Manager in C drive. Are these OK, since they both will be installed under the C:\usr folder?
What precaution we need to install these two SAP components in the same drive (C)?
I am installing both components in MS Window Server 2008 R2 SP1 with MS SQL Server 2005 SP3.
Thanks,
KC

Hi, Nick.
Sorry, I missed the "IDES". I am installing SAP ECC6.0 EHP4 IDES system for training purpose within the organization.
I am referring to the Installation Guide - SAP ERP 6.0 EHP Ready ABAP on Window MS SQL Server (Based on NW 7.0 incl EHP 1). All downloaded installation files are from: EHP4 for SAP ERP 6.0/NW7.01 --> IDES --> --> Widnows Server --> MS SQL Server.
The OS is installed in C drive.
I have allocated 250GB in C drive and 200GB in D drive from SAN.
For IDES system (I know it is similar to the standard ECC), is it also recommended to install in D drive (separate from the OS)?
In this case, should I install both Solution Manger and IDES in D drive?
Or what is the best combination where I should install these two systems?
Thanks,
KC

Pagefile for SAP Erp2005 and Solution Manager 4.0

Hi all,
I've installed SAP ERP2005 and Solution Manager 4.0 on the same server with Windows 2003 Standard 32bit.
The RAM on this server is 3325MB.
How many paging file I must configure???
At the moment I configured the pagefile size as defined in the installation guide:
1 RAM + 8GB that is 12285MB.
Is it correct????
For both instance I set the PHYS_MEM parameter to 2328 (70% of the RAM)...is it correct??
P.S. How to calculate the [BE] parameters??
[BE] = maximum possible number of user calculated from the size of physical main memory
Thanks in advanced

I agree with Yaroslav,
you should NOT set those values:
em/initial_size_MB |----    [PM] |----    [PM]   |Mbyte     |
|---    em/max_size_MB |---    20000 |---   100000   |Mbyte     |
| em/address_space_MB |-----    512 |-----   4096   |Mbyte     |
|---- ztta/roll_first |-------    1 |-------    1   |Byte      |
|---    ztta/roll_area |--- 2000000 |--- 3000000   |Byte      |
| ztta/roll_extension | 2000000000 | 2000000000   |Byte      |
|    abap/heap_area_dia | 2000000000 |           2000000000   |Byte     |
| abap/heap_area_nondia | 2000000000 |           0 |Byte      |
| abap/heap_area_total | 2000000000 |[PM]*1048576   |Byte      |
|-    rdisp/ROLL_MAXFS | [BE] * 100   | [BE] * 100   |8KB Block |
|---    rdisp/ROLL_SHM | [BE] * 100   | [BE] * 100   |8KB Block |
|---    rdisp/PG_MAXFS |---    32768 |---    32768   |8KB Block |
|-----    rdisp/PG_SHM |
so... that [BE] value is not to be used.

I just bought a new mac book pro 13'' and i bought a toshiba 1tb hard drive aswell, i formatted it to mac but it will not show up on my tv so i can watch movies? and solutions or reasons why?

TVs don't support "Mac OS Extended (Journaled)", so you will probably have to use FAT32. To format the external drive, follow the same steps as you did to format it with "Mac OS Extended (Journaled), but in the erasing screen, select "MS-DOS (FAT)" as "Format". Note that FAT32 isn't compatible with files bigger than 4 GB. Also, you may have to format the external drive in a PC
