About Web Dynpro Structure Design

hi,
How can i use the MVC design paradigm in my web
dynpro application?
Thanks a lot!

hi pei.....
           the model is your overall flow logic and the structure of the application or you can also say it as your background..
           the view is what the user sees. this is what you design.
           controller is the various controllers available in webdynpro abap. the main is the component controller which acts as a global controller.

Authorization about Web Dynpro ABAP

Dear all:
I have some problem withs the authorization about the web dynpro for abap.Please give me some advices.
For example: In my web dynpro abap,i have two tabs,one is "upload",anthor is "preview".Now there are two users,
in this example ,i assume user A and user B.If user A have the authorization of "Upload",and the user B have "Preview".
Now how can i solve the problem ? If i do not want to use the code to implement it , is there any solution for it ? Thank you ~
Best wishes !

Hi,
There are many ways to achieve this, but without code changes I guess this would be the easiest route:
Create 2 application configurations: one with Upload button Hidden and other with Preview Button Hidden.
Now to run you application you have 2 URL's by vritue of 2 application configurations.
Give the appropriate URL to required set of people.
Learn more about [App Configuration Here|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/media/uuid/af5e19e7-0b01-0010-37af-bc816f9a240c]

How to include Text file in Web Dynpro structure

Hi Guys,
I know that you can add a "File" object against a Java project (right click on project: New -> File).
Is this possible with WebDynpro? In other words, can I add a Text file "object" against my DC? I need such a File because I need to store text values in it that I read in my View Contoller.
Any suggestions?
Christiaan

Hi
Yes
Select the Navigator view --select the dc --right click --new --other --general --- here u will get the option .
Note : put your file only under src--make one folder say util and then put your file here.

Question about meta-data of Web Dynpro ABAP / Web Dynpro Java

Hello together,
everywhere I can read, that Web Dynpro meta-data is platform independent.
I´ve read into a book, that the meta-data of Web Dynpro Java is saved as XML and
that Web-Dynpro Java Runtime generates runnable classes and sourcecode out of this...
- What about Web-Dynpro ABAP? Is Meta-code in ABAP is saved in XML too?
- just for theory: is ist possible to take the meta-data of a Web-Dynpro ABAP component and
generate a Web-Dynpro Java Component out of this?
I tried to find it out but i failed... In table WDR_RR_LOAD (is this the right one?) I found only the
field data. But this is a RAWSTRING and I don´t know how to make I "readable".
I must know this for my thesis for my studies, not for work.
Thank you very much !!!!
Greetings,
Oliver

Me again,
I am not sure if I understood it right...
The meta-data which describes the visual part of a view is saved as XML and
would be rendered i.e. in the webbrowser... Right?
What about the meta-data of the Web Dynpro application?
Is this meta-code into an other structure or XML too?
Thank you very much.
Many Greetings,
Oliver

Basic knowledge about Sap Netweaver, Web As, Web Dynpro

Hi guys,
I am a new nut guy trying to understand Sap NetWeaver. Could you guys explain to me just briefly in the most simplest ordinary terms about points below. I tried to read documentations but do not understand completely.
1) What is Sap NetWeaver? Does it comes with several components?
2) What is Web AS?? what does it serve?
3) I heard about Web Dynpro for Java and Web Dynpro for Abap. They are used to develop Web applications in Java language and the other in Abap language. I'm interested just on knowing the Java side.
I just want to understand the hardware systtem achitecture and associated software to be installed.
Now for Java, I heard that we need to install Web Developper Studio, rite?? then which version should I install, Sap Netweaver SP16 or Sap Neweaver 2004 or Sap Netweaver 2004s?? where can i find it?? should it be installed in front end station? do i need Java?
Now for Web AS, where do i install it??
I'm totally new in Sap NetWeaver
Thanks a lot guys

Hi Ralph, I will try to keep it simple.

1) What is Sap NetWeaver? Does it comes with several components?

SAP Netweaver is the platform in which all SAP software runs on top of. For example R/3 ran on the "Basis" layer, this is simular in ECC6.0, where ECC is the R/3 part and Netweaver(ABAP stack) is the "Basis" Layer. With Netweaver you get two stacks, ABAP and Java. SAP components run on one or the other. Netweaver includes, but is not limited to:
Netweaver Application Server(formerly called WebAS)
Netweaver Portal(formerly called EP)
Netweaver XI(I think there is a new name for this)
etc.

2) What is Web AS?? what does it serve?

WebAS is now called Netweaver Application Server, this is the basis for all applications, whether ABAP or java based. For example the ECC(R/3 component) runs on the ABAP stack of Netweaver Application Server, the Netweaver Portal runs on the Java stack of NW Application Server.

3) I heard about Web Dynpro for Java and Web Dynpro for Abap. They are used to develop Web applications in Java language and the other in Abap language. I'm interested just on knowing the Java side.

For the java side, you develop the webdynpro applications locally on your laptop using NWDS(Netweaver Developer Studio) and then deploy this application to the Netweaver Application Server(java stack). You can then implement the application into an iView in the NW Portal.
http://help.sap.com/saphelp_nw2004s/helpdata/en/15/0d4f21c17c8044af4868130e9fea07/frameset.htm

I just want to understand the hardware systtem achitecture and associated software to be installed.
Now for Java, I heard that we need to install Web Developper Studio, rite?? then which version should I install, Sap Netweaver SP16 or Sap Neweaver 2004 or Sap Netweaver 2004s?? where can i find it?? should it be installed in front end station? do i need Java?
Now for Web AS, where do i install it??

Which NWDS to install depends on the version of the java engine in which you are working with. The rule is that you keep the version of NWDS in sync with the version of the Netweaver Application Server(java engine). Usually the NW AS, is intalled on a standalone server(not your laptop), but you can install sneak preview editions on your laptop for testing .
I hope this helps a little.

About configuration web dynpro abap

we have ecc5.0 and we cant use web dynpro there. can anyone please tell me how can we use web dynpro there? is it related any sap license related issue? please help me about giving me some knowledge about web dynpro installation and use.
From web every user should need one sap id or one common id can be use for login through web.

>please help me about giving me some knowledge about web dynpro installation and use.
There simply is not option to install or configure Web Dynpro ABAP on ECC 5.0 or earlier. Web Dynpro ABAP is part of the SAP_BASIS Software Component. The versions of ECC 5.0 and earlier simply didn't contain Web Dynpro ABAP. It was new in ECC 6.0.
If you want to create Web Dynpro applications, consider building a standalone ABAP or Java Application Server as a separate instance. You can then do Web Dynpro ABAP or Java development on this standalone instance and make RFC and Web Service calls to your older ECC 5.0 system.

Sharing a web dynpro project

I want to know few details about Web dynpro project
1.I have created a wd project and started working on it creating some views etc. Same is being done by another colegue of mine. for example he also had created same structure of the project started working on some views . What all ( files)should i copy from his system so that the views created by him is available to me.
How sharing of this works other than pvcs OR cvs
2. Is it possible for me to update my model using a modified wsdl?

Hi Sujesh,
For sharing the web dynpro projcts you need JDI(Java Develpment Infrastructure) installed in your server. In that you need DTR(Design Time Repository) service of JDI. For details on this try this link.

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.

Web Dynpro Application throws NoClassDefFoundError for IAspect

Hi All
I decided to teach myself a little bit more about Web Dynpros and the Composite Application Framework and as such started working through SAP's tutorials. Currently I'm busy with 'Using a Composite Application via a Web Dynpro UI' - at the section where I need to programmatically populate a DropDownByKey with the location names. I followed the tutorial's instructions step for step, but after deploying and running my application I receive the following error message:
java.lang.NoClassDefFoundError: com/sap/tc/col/client/generic/api/IAspect
Sometimes IAspect is replaced by IStructure.
The detailed error provides this message:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component com.sap.carpool.travel.Travel. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
It seems as if it is struggling to find the DC containing IAspect and IStructure, but I have included
tc/col/runtime (default)
in the 'Used DCs' of my Web Dynpro DC.
Any ideas what might be causing this or how to fix it?
Thanks in advance,
JP

Hi Valery,
Thanks for the reply.
It seems like that to me as well. I can use the code as I've imported
com.sap.tc.col.client.generic.api.IAspect;
, but when it actually tries and load the implementation it can't find it?
Unfortunately, checking the run-time (or build or deploy time) checkboxes on tc/col/runtime did not help.
