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]
Hope this helps.

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.

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.

Rich Heilman

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

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.

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.

How to include source code in web dynpro java deployment

Hi,
We dont have NWDI.
We are creating ear files out of web dynpro applications packaging them as sca files and deploying them in server.
But the source code is not included in ear.
How to include source code with your ear/sca , so that when anyone downloads the sca file later, they are build the Project in the studio.
How would they typically download? Do they require NWDI ,
Right now we dont have NWDI in place, but we want to do is parcel the applications such that the source code should be available at a later time for download.
This is possible with .par files , but what about web dynpro?
Thanks,
Deb

If you are not using NWDI use the _comp file.

Pushbutton Problem in web dynpro

hi there,
i have a sap standard web dynpro. in the portal i have the UI elements tree to personalize the dynpro.
there is a part where i have 2 push-buttons:
Pushbutton 1
Pushbotton 2
by default Pushbutton 1 is activated. Now i want to hide Pushbutton 1 for the user. So far so good, i can do it in the UI elements tree and change it.
The Pushbutton 1 now is hidden. BUT: i want to have Pushbutton 2 activated automaticly. Now the pusbutton is not 'ON'.
how can i achive this with the UI elements tree control in Portal. I am NOT a JAVA-developer, i have no idea about web dynpro, i am coming from abap side. so i DON'T want to modify the web dynpro.....i need a way to do it with the personalization function in portal.
reg, Martin

Hi,
I assume that your requirement is to show one button at a time button1 or button2.
create 2 context attribute of type Visibility under uielementdefinition.
bind one of the context to button1's visibility property and the other to the button2's visibility property.
Now, in your code as per your condition, you can set the visibility as
wdContext.currentContextElement().set<visible1>(WDVisibility.VISIBLE);//To Show
wdContext.currentContextElement().set<visible1>(WDVisibility.NONE);//To Hide
