External debugging of ABAP from NWDS in web dynpro java

Hello Experts,
Like a while a ago, I remember on SDN there was a video for external debugging tutorial. Can any one point me to that or any other documentation for doing external debug from NWDS.
Thanks,
Sharath

HI James!!!
You can find a video presentation for external debugging of WD JAVA application at:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/com.sap.km.cm.docs/library/elearning/user-interface-technology/web%20dynpro/wd%20java/web%20dynpro%20java%20with%20an%20adaptive%20rfc%20model/web%20dynpro%20java%20with%20an%20adaptive%20rfc%20model%3a%20debugging/resources/eventplayer.htm

Web Dynpro JAVA VS. Web Dynpro ABAP

Hi,
I'm interested in advantages and disadvantages of WD JAVA & WD ABAP. Could anybody give me some "detailed" information about it?
We need any information you can give us.

Sharam

Hi,
Web Dynpro for ABAP:
Web Dynpro for ABAP or Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web applications in the ABAP environment. It consists of a runtime environment and a graphical development environment with special Web Dynpro tools that are integrated in the ABAP Workbench (SE80).
The use of declarative and graphical tools significantly reduces the implementation effort
1) Web Dynpro supports a structured design process
2) Strict separation between layout and business data
3) Reuse and better maintainability by using components
4) Automatic operation of the Web Dynpro application using the keyboard
5) User interface accessibility is supported
6) Full integration in the reliable ABAP development environment

Web Dynpro for Java:
Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
Web Dynpro helps you with the development of Web applications by:
1) Ensuring platform-independence with the meta model approach
2) Minimizing the implementation effort through declarative programming
3) Supporting a structured design process by applying the model view controller paradigm
4) Providing reuse and better maintainability by using components
5) Providing graphical support with tools in the Web Dynpro perspective
6) Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.

The concept of Web Dynpro ABAP is identical with Web Dynpro Java and offers more or less the same functions

Topics needed in abap to learn web dynpro abap

Hi experts,
I have experience on web dynpro java..planing to learn web dynpro abap,so could you please tell me what are the areas in abap i should learn before starting web dynpro abap.
regards
rahul

The main difference between WD Java and ABAP, would be coding using ABAP OOPS.
So, firstly, go through SAP documentation on ABAP OOPS/Classes.
There are some concepts like configuration controller specifix to WD ABAP. However, once you get a understanding of coding in ABAP OOPS you should be able to understand the new concepts.
Also, look at developing and working on application in WD ABAP. Hands-on experience is critical to develop your skills, not just in WD ABAP.

Web Dynpro Java Internationalization and backend ABAP function modules

Friends,
I have a requirement where I want my Web Dynpro Java application to support BRAZIL and CHINESE.
I have been through the sample programs and tutorials and I understand how to support my application in these 2 languages. The challenge I am facing is how to communicate the language to the backend code (ABAP function modules) so that the function modules can written language specific error messages and texts.
I searched SDN but could not find anything. Your help is appreciated.

Prashant,
When you are configuring JCo connection in WebDynpro Content Administrator, just left language settings blank for metadata connection (you may do the same for data connection). Now WD will supply language of currently logged-in user when obtaining connection settings from system landscape and you'll get necessary functionality.
By default locale of user determined by parameter sap-locale (sap-locale=de_DE for example), settings of user's browser and lastly preferences of user stored in UME.
Btw, BRAZIL (or Portugees for this matter) is not fully supported language by SAP, so R/3 side may be not translated or partly translated.

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
 I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
 procedure"
 Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
 signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance
Regards
Piyush

Web Dynpro Java to Web Dynpro ABAP

Hi all,
I am a web dynpro java developer with more than 3 years of portal development experience.
I am now put into a project with web dynpro ABAP(ESS/MSS customization).
Would like to know whether I should start concentrating more on ABAP or SAP HR?
I dont have any ABAP programming exp except that attended a training few years back.
And on SAP HR,dont have much exp except that have some knowledge on ESS customization in dynpro java.
Please let me know where I should start to get myself refreshed before starting my work.
Any advice/docs are invited.
Also,please let me know whether there is any NWDI required for ESS/MSS customization in webdynpro ABAP.
Thanks
Meena

Hi Meena,
As you have good experience of Web Dynpro JAVA.
I think you just need to comcentrate on ABAP skills.
You need not concentrate on SAP HR as ur work is technical your functional guys will take care of HR module and will help you.
For starting i would suggest you to just go through the basics of ABAP like Work areas , internal tables etc.
Then start doing some WD ABAP hands on.
My scenario is similar.
I am a portal and WD JAVA person and this is my first WD ABAP assignment.
I followed the above approach.
You will find many concepts similar to WD JAVA as this is just the ABAP flavour of Web Dynpro.
The below link will help you a lot

I hope it helps.

I want to learn web dynpro in UK

i want to learn web dynpro in UK through remote servers by self learning.WHO provides remote servers.what r the pre requisites for webdynpro for ABAP

You can install your own Server from [this link|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/80fd9a0a-e306-2a10-c896-b84c77c13ed2].

Created in Web dynpro Java or Web dynpro ABAP

hi all,
I have a web application running. Its UI is created either in web dynpro java or web dynpro ABAP. Is there any way by which we can find out that in which form of UI technology is it created; in web dynrpo java or web dynpro ABAP ?

Hi,
I am really not sure if this is recommended..
Try some negative testing on the application. If the application crashes, the trace of the error occured will tell you what kind of development has been adopted for the Web Dynpro application.
Another hint can be the port number in the Application URL. If it is not 50xxx, and is somewht like 8xxx, it is surely Web Dynpro for ABAP.

Alka.

BSP / Web-Dynpro (Java / Abap) what to use in this case ?

Hi all,
i have some questions about all this BSP/Web-Dynpro stuff. We have an application (for health care written in Visual Studio) out there at our customers. Some of these customers are using SAP as their backend system. So we've writte some backend functionality (a cash processing, additional reports, a special invoice system etc.etc.) in Abap and Abap-Objects. Actually we are planing a new release for this backend stuff which is using the normal SAP Gui.
Maybe we plan for the next release to convert our app to a Web based app and we discuss what SAP technology we should use for that.
Here are my questions :
- When and why should we use Web-Dynpro (Java) ?
- Can't we use BSP ?
- Is there any future for BSP ?
- When will Web-Dynpro for ABAP be released (actually we are not a Java Shop so Abap is prefered)?
Hope someone can answer my question.
Greetings
Henning

If you don't mind, I am going to terminate discussion of Web Dynpro ABAP here. It is not that I want to, but we are in a difficult position with this development, and can not really discuss it too much.
But, let me first make a few (last) comments:
(*) BSP is available since WebAS 610 (which is now nearly at the end of its lifetime). WebAS 620 is the main platform out there, with NW04 (WebAS 640) now shipping, and the next product is inevitably coming. If you keep in mind that SAP supports each release at least 7 years, and we will be shipping BSP in an upcoming release, you can see that with BSP you are not going to left stranded for many years to come.
(*) Web Dynpro Java is out and shipping. A very nice development environment. You can build nice things with it.
(*) Web Dynpro ABAP: it will become a very nice product as well. We should know :). But, it will definitely not ship on NW04 platform. Which unfortunately means the next great NW shipment (both naming and date is not available).
From our experience, most people seem to make their decisions based on the available Java versus ABAP skills in the shop. However, the other factor to look at is also "pixel perfect" rendering. Only with BSP can you influence the rendering. Web Dynpro is more a development platform for business applications, and as such they must conform to the designated model/concepts, etc.

Full ABAP Edition-Trial (with Web Dynpro for ABAP) Max DB data volume

I recently installed Full ABAP Edition-Trial (with Web Dynpro for ABAP)- SPS08.
http://static.flickr.com/89/243544270_91e713e3a3_o.jpg
as you can see, it's already 92% acquired ( just after installation)
Is it correct?
or it's better to add another volume?
The other question is
according to the license installation guide,
it sounds like we can delete the temp licese with SAP*.
so I did like that but i got the following message
http://static.flickr.com/81/243546622_bc99d1af2b_o.jpg
Well, I could delete the old license with BCUSER.
Thanks,
David

Hello,
to your first question.
The MaxDB database has a feature which can
increase the database automatically.
This ( auto_extend ) is turned on for the SDN Preview
installation.
That means the database should extend a further datavolume
automatically when the filling level gets over 90%.
In your case the database already added two more datavolumes. The installation only creates one.
Best regards, Stefan

I have made Web Dynpro ABAP iView calling Web Dynpro ABAP timesheet and linked it with page.
But It is showing an error 'Web Dynpro Application CATDATARECORD does not exist'.
Please suggest what other changes needs to be done.

Hi Anurag,
I have added new Web Dynpro ABAP iView to the same page in which Web Dynpro JAVA iview was added and made ABAP iview visible.
And this page is already assigned to role.
