Hi,
Web Dynpro is the SAP programming model for user interfaces (UIs).
It provides a programming framework within which you can achieve a:
u2022 Clear separation of business logic and display logic
u2022 An application specification that is both:
Client neutral and
Backend neutral
It consists of a runtime environment and a graphical development environment with special Web-Dynpro tools that are integrated in the SAP NetWeaver Developer Studio
The Web Dynpro technology provides a development and runtime environment for Web applications and enhances classical Web development to build easily adaptable user interfaces. SAP's Web Dyn-pro technology closes significant gaps between typical Web development tools and the needs of cost-effective, responsive, easy-to-use, maintainable, and professional browser-based user interfaces for business solutions. Web Dynpro uses design principles similar to SAP's Dynpro technology, but it is a completely new technology geared exclusively towards Web applications. Its main features include the following:
u2022 Usability
u2022 Abstract modelling
u2022 Personalization and customization
u2022 Separation of presentation layers and business logic
u2022 Generic services
u2022 Portability
Web Dynpro applications run in the SAP Enterprise Portal.
See https://www.sdn.sap.com/irj/sdn/nw-ui for more information.

I have 3dparty software wirelessly with a cryptographic authentication system without my consent (seems to be new technology developed by stanford) obtaining ownership of my iPhone 4s software and controlling it with remote device to jail break. Now what?

I have 3rd party software wirelessly injected and used on my iphone with a cryptographic authentication system without my consent (seems to be new technology developed by stanford and apple security is not updated for this technology) obtaining ownership of my iPhone 4s software and controlling it with remote device to jail breaking my phone, adding and removing software, changing settings all from a remotely controled device from different location (I have a Mac address I'd of this device to know for sure). Almost undetectable. When I look at the legal section of my phone it shows a list of all the unauthorized 3rd party software "as is" copyright encrypted on the phone. This is the most basic way to legally steal software of any kind. Because of this legalality 3rd party ownership have total control of certain software correlated with hardware use including visualization technology, etc. most people luckily will never have this happen to them so it's unlikely many readers have not a clue of what I'm saying currently. Either way, without needing to obtain specific warranty of any kind "as is" copyright control makes system restores not a solution because the source code is not directly encrypted on the actual hardware device only a copy right notice must appear on the specific device 3rd party software validation making it extremely difficult for me to take control of the situation. Apple claims their iOS technology prevents this type copyright obstruction from being possible, however, according to my phone a new form of technology was used developed by Tom wu of Stanford university called the STANFORD SRP AUTHENTICATION TECHNOLOGY which uses Some form of cryptographic authentication system and uses quote "secure remote password" which seems to suceed in hacking iOS apple technology apple claims is not possible to jailbreak an unstolen phone or without the owners consent As well as loading the device with 3rd party copyright Notices to make all of this legalized. My phone shows atleast 30 pages worth of legalized 3rd party copyright permissions! Yesterday my apple care provider labeled me a jailbreaker and refused to look at my legal documented proof which completely blew my mind because it voides my apple care contract I spent 100 on. This employee did not take all factors into consideration and made quick assumptions as well as verbally speaking to me as I'm an automatic criminal. I left the store yesterday with no payed insurance help on a problem I had no control over and couldn't prevent, leaving with voided contracts. This is an apple users worst nightmare and I have spent days researching all of this like i am some kind of lawyer only to be able to use my phone the way it should and spent alot of money on. I can legally backup any claim I have just wrote above currently and have a large source of data collected to prove apple is wrong in voiding insurance support on this issue. The problem lies in apple avoiding and not wanting to believe their software can legally be obtained ot "hacked". Yet still labeled a jailbreaker basically.. What should I do????? Been to local apple store 3 times and rebooted my phone as well sprint service restore 4 times and spoke with reps twiice on the phone. Spoke with my phone provider who said apple has full control over these matters so they can't help me. My case is according to apple "still open"...Anyone else heard of this or of Stanford's office of technology licensing? Maybe I need to buy a blackberry again or just use a landline so I can stop being my own lawyer and focus on other productive areas in life instead of this horrible mess. I shouldn't have to prove to apple I not a jailbreaker they should have to prove I'm one before voiding support I desperately need!!

I assume u guys don't understand what open source software is
Yes, I think most of us do understand what open source software is. It sounds as if you don't. Here's some information:
Open-source software (OSS) is computer software that is available in source code form: the source code and certain other rights normally reserved forcopyright holders are provided under an open-source license that permits users to study, change, improve and at times also to distribute the software.
Open source software is very often developed in a public, collaborative manner. Open-source software is the most prominent example of open-sourcedevelopment and often compared to (technically defined) user-generated content or (legally defined) open content movements.
from http://en.wikipedia.org/wiki/Open_source_software
Yes, Tom Wu of Stanford wrote a paper on something called Secure Remote Access Protocol. It's a form of Asymetric Key Exchange and has nothing to do with hacking anything. It's actually intended to protect data.

Can I add a New Folder to existing Business Area with Command Line?

Hi,
Can I add a New Folder to existing Business Area with Command Line in Discoverer (java or executable)? I am trying to do this with /load...
/connect walkep_apps/walkep@smpdev1
/load Visualizations /eul walkep_apps /user smp_naps_apps /object VISUAL_20K /capitalize /remove_prefix /insert_blanks
/aggregate DETAIL /show_progress
... but this creates a new business area, "Visualizations 1", which is not what we want! We want to add the VISUAL_20K to the existing "Visualizations" business area. Many thanks in advance.
Phil

Bang on. thanks
three's always an obvious solution.
I'll post another question about how to attached a file into a Mail message which is automatically compressed/zipped. Or do i have to find the file in Finder, compress it and then attached it?

Question for Hatter; re: Newer Technology eSATA Extender Cable

Greetings Hatter,
I read in a recent post that you were using the Newer Technology Extender Cable to hook up drives to the extra 2 SATA ports on the Mac Pro's logic board.
I have a FirmTek enclosure (and a bunch of internal drives) that I used with my G5, and I'd like to continue using it with the Mac Pro.
Quick question: how is the cable working for you? Any problems?
Thank you for all the valuable information you post on these forums.
H.

The other threads on Newer kit, and www.xlr8yourmac.com report, are a good resource.
Drives have to be on at startup; can't be unmounted and can't turn on or off while the system is up. Excellent otherwise.
I added a 1x 2-channel controller also so I now have two choices and makes it easy to work with 4 external drives.
It was a real sweat to connect the Newer SATA cable to inside ports.
In the end, using the SeriTek (or Sonnet Tempo) makes more sense overall.

How does one tell if the J2EE services are running with Unlimited

How does one tell if the J2EE services are running with Unlimited
security? We have applied the export Policy to the server but we do notsee any reference to it running with it. .we apply the Service packs SAP now upgrades that JAVA as well . Do that process treat the JAVA
lib/security area correctly.

Just out of curiosity... Is there something you do
like about Mac/Apple?
To answer your question: no, not really. However, the points that I made here were about Safari and accompanying utilities, not about Apple in general.
If it makes you feel any better, I am just as, or even more, critical of Micro$oft as the occasions arise...Windoze Vista is the most recent occasion and has given sufficient reasons and opportunities to vent my spleen that I actually have eased up on Apple, politicians, nut-case religious extremists, cell phone owners, and the Department of Homeland Paranioa, etc., due to an exhaustion of creative energy.

i wanted to know how does technical support work via icloud and is there any new technology out that helps providing technical support?

basically I’m doing a project were I wanted to find out if there are recent technology out that provides technical support for example they do it with remote access but is they any new ways that they can support us and just wanted to find out if icloud gives technical support then how?

Thanks Srinivasan T
We had the same thought but cannot see why this would produce the fault shown in our log files.
The errors seem to be in 2 specific tables BC_CPT_ACTION and BC_CPT_MODULE being unable to convert a column size from 256 chars to 100 chars.
We did a lot of searching for various things and found a SAPnote 939108 which had a similar error in it and recommended deleting the data in the erroring table.
So we had a quick look at our QA/Test & production portals and these tables are both empty in both these other 2 systems. So we've decide to copy these 2 tables and then delete the data from the originals in our development portal database and restarted the patch deployment.
This time the patch deployment has successfully converted the tables and has moved passed the stage at which it was failing.
The patch deployment is still running so it'll be a while before we know for certain whether we've overcome the problem.
Many Thanks though for taking the time to try to solve my problem.

Steve

Adding new method into String.java (just for personal usage)

For some reason, it kept bringing in the old String.class, even I updated it the rt.jar with the new String.class. I even checked it with jar -tvf rt.jar. It has the new String.class. However, it seemed to constantly loading in the old one. Unless I use bootclasspath. The followng is the test :
1.     I add a new function to String.java
a.     : goody() { return this is a test method; }
2.     To compile:
a.     javac -bootclasspath ".\;C:\Program Files\Java\jdk1.6.0_03\jre\lib\rt.jar" String.java
jar uf rt.jar java/lang/String.class
3.     To test with file test.java where it calls String.goody()
a.     To make sure it is not pulling in old code, I had to copy the new rt.jar to my test directory:
i.     copy "C:\Program Files\Java\jdk1.6.0_03\jre\lib\rt.jar .\
4.     compile my test.java:
a.     javac -bootclasspath .\rt.jar test.java
5.     Execute the jvm:
a.     java -Xbootclasspath:.\rt.jar;.\; test
6.     I got output : this is test method
=========================
if I use the regular : java classpath where the new classpath does indeed reside in, it claims the symbol not found. I have to copy the rt.jar to my local and use -Xbootclasspath. Suggestion? Or, this is really the only way to be able to call a new method installed in String.class?

You must replace it in the VM directory or use the bootpath options. There is no other way.
Note that you mess up with what you are doing (replacing the rt.jar way) that not only will you not be able to run, not even to get an exception, but you will not be able to compile either.

Old geezer with new technology question

I am old and I have an old cell phone.
It will make calls and receive calls.
I am thinking about venturing to some new technology... an iPhone maybe?
Wondering if it will do ONE THING that I might be wanting to do.
With an iPhone... can you:
make a video/audio recording AND simultaneously, real time, upload it to... somewhere
as in... I have an iCloud account, maybe there?
Thanks,
James
P.S. Please make any answers at kindergarten level, and don't assume I know a bunch of terms or concepts, I probably don't. Thanks.
P.P.S. If you need more information from me to answer/help, just ask and i will try to provide.

Thank you, Novicii.
I don’t have Facebook or Twitter (and WON’T), so they’re out.
And don’t know about WiFi areas.
But if I have an iCloud account and (got) a cellular data plan (when I got my iPhone) then it sounds like I could do this.
Only two questions:
1-
You talk about uploading “photos”.
I’m talking about uploading continuously running video as it is still recording.
Will it (progressively) upload the video (pari passu) WHILST the video is still in the process of recording?
Or would you need to END the video recording before it would SEND?
2-
And the link you gave me (great link!)
Talks about PhotoStream vs. Shared PhotoStream and the requirements.
I’ve only got OSX 10.7.5 but it looks like that would suffice for (non-shared) PhotoStream, which would be fine for me.
10.7.5?
3-
But again, all I saw the link talking about was “Photos” (admit I haven't parsed my way through all there completely)
Does everything they say on that page you linked about photos apply to VIDEO?
Thanks Novicii!
James

My question is this: Can good teaching be enhanced with new technology?

Can good teaching be enhanced with new technology? Adobe eLearning Suites is certainly a high-end product with many users and a lot of finance and research behind it. My question is why? Where is eLearning going and, again, is face-to-face teaching going the way of the dodo as a result of this new type of technology?

Hello,
Hope you were not too startled by my reaction, your question reminds me of all the antagonism I have to struggle with every day in the college (with colleagues and management), hence my 'passionate' reaction. Reactions like 'I've written a good course some years ago, I'm a good teacher, why should I need all those hypes you are talking about...'. But that is not what you are interested in...
You asked about tests reported. Vaguely I remember (from a training in 2009) some tests, but have to search for the right references. My personal opinion about those tests is that first of all one should know precisely what to test: when is a training successful or more successful? What do you want to measure: it is very easy to test the 'short time' knowledge acquired by a training, that is what we academics are doing most of the time. But I'm not sure that this really is a measure for training success. Who would dare to postpone the test a couple of months after the end of the training?
I'm still teaching F2F, but nowadays not at all like I did 20 yrs ago. Was a rather good teacher, my lessons were very good prepared, with a clear structure and was able to explain in a language comprehensible to most of the students, felt successful when at the end of a lesson, trying to test if the proposed subject was clear to (almost) everone the result was positive. Students felt good too: at that moment, leaving the classroom, they had understood what I had tried to explain. Everyone happy. Was this good teaching? There was a good written course, but when studying the course for the final exam, students were confident, they had understood everything in the lesson, but ... that was so long ago... And, like Rick also pointed out, a lot of questions arrived, and I started explaining again, and again... Who feels well? Some colleagues are still happy with every answer they can give, but I got pretty unhappy. Some students do not dare to ask questions, some need 'audio', others need 'video', ...
Doing some sort of blended learning now: try to present some structure, basic ideas F2F and get them to work on their own. Most of them do not like to read long written courses, so give them small chunks they can digest when they need it for their tasks. And use everything to make it less boring: video, audio, interactivity, self-assessments, let them twitter, chat, discuss on a forum, blog, create a wiki, search, explain to each other... We have the tools, just need some creativity.
Did I do some research with my students? Not in the regular structured way tests are normally conducted. But I'm often starting a lesson with a survey (on our LMS) where students (anonymously) are given their idea about their proper knowledge about the subject, about the used techniques, about their 'digestion' of the previous lesson, about the work they have done: purpose is for me to have some feedback and a base to go on, for each student to have an idea of his position in the group. We are looking at the statistics together and discussing it briefly. When introducing some new 'hype' there is never an obligation, they can try it out and give their opinion. Just an example: when starting to offer CP-SWF's I offered demonstrations, training simulations and assessments. Feedback from the students pushed me just at never creating demo's again. For the moment I introduced Twitter for a project, will have their feedback after next week and judge then.
Sorry again for a too long answer (begging you pardon, Rick too). When I find the references I have been mentioning I'll post them. Now it is getting rather late, have quite a lot of meetings tomorrow with students.

Anyone had tested the Newer Technology MAXPower G4/7447A 1.6GHz upgrade?

Hello.
Does anyone had any experience with the Newer Technology MAXPower G4/7447A 1.6GHz Processor Upgrade ?
Is it good?
Macjaime

Hi-
The 7447 processor upgrades are good stable upgrades. The 7447 is fairly cool and efficient, and will boost overall performance.
The weak point of the processor upgrade (compared to the 7448) is the cache. It only has the L2, and it is only 512KB.
The OWC 7445 1.5ghz processor with the 2MB L3 cache would be a much stronger upgrade than the 1.6ghz 7447. Unless the 7447 is greater than 1.8ghz, the slower 7455 processor with bigger cache will be the better performer. This is especially true in video applications.

When does the new version of J2EE will be available?

Hi,
Do you know, When does the new version of J2EE will be available?
Who can we ask for improvements or fixes? Or it is just the people that has bought suport?
I hope they can release 'pingConnectionPool' code, so people can trace jdbc driver problems.
Thanks,
Lorenzo Jim�nez

Thanks for your concern,
Well, to tell the truth, the same driver is working ok in the application server without a connection pool with "connection = DriverManager.getConnection(url, username, password)".
Also works ok on IBM websphere, Jakarta Tomcat, with or without pool. Its is just Sun's connection pool. Also I have seen other threads showing JSK 1.4 is not quite compatible like this one:
http://forum.java.sun.com/thread.jsp?forum=136&thread=499803&tstart=0&trange=15
I tried every conceivable parameter; even I looked at the proper documentation at
http://publib.boulder.ibm.com/iseries/v5r1/ic2924/index.htm?info/rzahh/page1.htm
and forums, and it seems that no one can know or can help us about this error because is particulary at Sun app server. So this is the server.log:

Did Adobe give Google & Yahoo new technology for Flash SEO?

I recently read that Adobe gave Google and Yahoo new technology so spiders can crawl thru Flash sites. Not pictures but text. I was wondering if anyone from Adobe could confirm this and if it really does work. As a designer I prefer to work in Flash because I can create more visually pleasing sites. I built my own portfolio site in Flash only to find out it couldn't be indexed! www.kholstudios.com I was heartbroken. That was about a year ago. I am about to begin one now and am not quite sure how to proceed at the moment. Flash or Dreamweaver? I am a newbe coder so please bare with me in the terminology department. Any input would be helpful.

advnturgal,
> What I would ultimately like to do is have an all Flash site that is
> indexable. I know that is stretching it, but if Google is indexing swfs,
> what would be the best method to attract the robots
     That's a good question, honestly. As far as I can tell, you really don't have to do much of anything. According to the URL from yesterday (along with its external references ---
     http://googlewebmastercentral.blogspot.com/2008/06/improved-flash-indexing.html
     http://www.sitemaps.org/faq.php
-- it really seems to me that Google (at least) is capable of "clicking buttons" and following at least some logic inside a SWF to "[explore] Flash files in the same way that a person would." The <meta> tag you showed belongs in the HTML document that embeds the SWF (that tag isn't supported among the few tags Flash Player recognizes), so while it may serve as a communications medium to indexing robots, all it presumably does is lead those robots to the HTML file. Whether that same "come hither" relates to SWF content inside such HTML documents, I'm afraid I don't know.
> Is there any trick to naming buttons or page titles in Flash?
     According to the Google blog post listed above, Google is "only discovering and indexing textual content in Flash files." If "textual content" includes symbol instance names -- I suppose it might -- then you could certainly try giving your target-able objects meaningful instance names (click the symbol on the stage, then look at the Property inspector to see the Instance Name input field). Be aware, though, that not every symbol supports instance names (graphic symbols don't). By the sound of it, though, Google reads textual content no matter what sort of symbol it appears in.
     On the face of it -- and this is conjecture on my part -- there doesn't seem to be a way to "tag" text inside your SWFs like there is with HTML (that is, by putting headings in <h1>, <h2> tags, or the like).
> I have also heard that linking to other websites is probably even better
> than using a lot of copy. How does that work exactly?
     Not all search engines care about linking (I think), but Google does. The more other sites link to your website (not you to theirs!), the more relevant Google considers your site. I don't think it's fair to suggest that linking from other sites is better than having useful copy ... the words on your own site are almost certainly the most important search keys. I suppose you could ask other websites to link to your own, but that could potentially get spammy on the part of the person asking.
> Do I have to negotiate with the other website to get permission to link.
> Is there special terminology for that?
     People occasionally link to my blog entries without permission, and I'm glad when they do, because it drives visitors to my site. If you choose to link to other sites, you'll be helping their page rank. The Internet is a public place, so as long as you link to publicly available content on someone else's site, you don't have to ask permission. If you think about it, that's exactly what sites like Google and Yahoo! do automatically! And it's also what I did by posting the two URLs a few paragraphs up. There's no special terminology I know of ... just "link" or "hyperlink".
> I know I have many questions, but this is the place to seek answers.
     This definitely is, and there are plenty of helpful people on all of these Adobe forums. Your particular line of questions is an interesting one, because it balances between HTML practices (think, the Dreamweaver forum) and Flash practices. In this case, I wish I knew more about the topic, but the links I've shown, while not exactly cornucopias of knowledge, are at least a good beginning.
     What I would do, in your case, is prepare at least some relevant copy (text) in HTML format and place that inside a <div> tag on the main page of your website. Use something like SWFObject (http://code.google.com/p/swfobject/) to replace the content of that <div> for people with JavaScript enabled and Flash Player installed. People who meet those requirements (most do!) will simply see your Flash content and never know the different. Google will index both the HTML content and your SWF(s). People who don't meet those requirements will nonetheless be able to read a summary of what your site is about -- that way, you reach the broadest possible audience.
