Environment for working with web dynpro

Hi All,
I am new to web Dynpro and would like to work on this. Please let me know what software i need to install to work on web dynpro. PLease provide all the necessary information.
Thanks,
Ramana Kishore.

Hi. THere are two flavors of webdynpo, you have the java side, and the ABAP side? Which do you want to work with?
For the java side, you will need to download and install a Netweaver Sneak Preview Java system as well as the Netweaver Developer Studio. The studio is the IDE which you will use to create your webdynpro applications, you then deploy to this java system to run the app.
For the ABAP side, you will need to download and install the Netweaver Sneak Preview ABAP system. Of course the IDE here is SE80 in the ABAP system. Webdynpro is built directly into SE80.
You can download all of this good stuff here on SDN at the following link.
https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/library/uuid/cfc19866-0401-0010-35b2-dc8158247fb6
The ABAP system is on the far right.
You can also check out the help on both.

What is the right sdk api to work with webi reports in BOXI Release 4?

Hello,
I just read in the omg model for rebean (sdk for working with webi report documents) that all functions to access the report structur and layout are no longer availabe beginning with Release 4.
Can anyone confirm, that this is the case?
Are those functions moved to a different SDK component?
Thanks in advance,
Bernd
Dokumentation about rebean _omd
u2022 The object model shows many funtions , classes in red which means:
Note: The Classes, Interfaces, and Methods marked in red are no longer functional from the SAP
BusinessObjects Business Intelligence Platform 4.0 release onwards.
u2022 Among those functions are all !! We need to analyze the report layout
u2022 No longer supported: DocumentInstance.getDictionary() , DocumentInstance.getOpenDocumentInfo(), DocumentInstance.getResourceManager(), DocumentInstance.getStructure()
u2022 Classes no longer supported: ReportElement, ReportDictionary, Query, QuerySorts, DataSourceObject(s), SQLDataProvider,QueryNode, DPExpression, QueryContainer, Link,
u2022 Classes no longet supported: ReportBody, ReportContainer, ReportStructure, ReportBlock, Graph, *Table
u2022 Classes no longer supported: Cell, PageHeaderFooter

Thank you for the information srrachna !
Well, the point with the report engine sdk is a surprise. What is the sense of new functionality when you cannot use it (spoken for the api processing), and in addition when the new functionality eliminate functionality which was available before in the sdk.
In my view this cut is to hard. The .pdf speaks from deprecated, but the blog and the information in the report engine api speaks a different language. The functionality is not just deprecated but no longer available.
Hope SAP will address that before relase 4 becomes GA in May 2011.

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

Problem in submit button on adobe form integrated with web dynpro

Hello,
I'm facing prob in triggering web dynpro event onSubmit for Interactive form.
I've created a submit button from web dynpro activex pallete on adobe form (integrated with web dynpro) to send the form as email.
Then in the web dynpro view where this form is embedded i have created an action against onSubmit event and called a method within this.
However, on clicking Submit button this event is not getting triggered.
Please let me know what is lacking in this process?
Thanks.

Hi,
I am also facing the same problem. i have developed a simple scenario under which user have to input his/her details and on submit button it will be updated to database.
I have tried the above solution but after adopting this solution all the editable fields become non-editable.
so the above solution is not working for me could you help me out.
I think ... try this....
When you create the Adobe Form from WebDynpro, you need to follow one step in SFP Transaction or inSE80 transaction. Open the Adobe Form in any one the transaction and now in SAP menu bar "Utilities" in that you will find the "INSERT THE WEBDYNPRO SCRIPT" just click on that one. Then you will see a new Script Object is being created with the name "ContainerFoundation_JS" under the "Variables" in the Heirarchy of the Object Pallete of the Adobe Form.
This step is mandatory to use the SUBMIT Button of the "WebDynpro Native", to trigger the OnSubmit event of the WebDynpro.
Thanks

Problems using Visual Composer with Web Dynpro runtime

I am currently trying to build a Visual Composer iView and we need to use the Web Dynpro runtime rather than Flash because it needs to work with a screen reader for users with sight problems. Which is a pity because Flash works fine. But when I use Web Dynpro runtime I'm getting the following problems:
a) When I define fields and pushbuttons in forms where Align Contents is set to Absolute, they do not appear at runtime in the positions in which I've placed them - all form elements are aligned vertically. The only other options are to align all fields vertically or align all fields horizontally. This lack of flexibility makes it rather difficult to create a good screen design; the only option seems to be to create a separate form for each set of differently aligned fields, which leads on to the next problem. .
b) When I define more than one form on a page, again at runtime the forms do not always appear in the positions in which I've placed them; the compiler seems to calculate how much space it needs to display the screen elements and then re-sizes and re-positions the forms accordingly, ignoring what I've told it to do.
c) Toolbar pushbuttons do not appear on forms (they do appear on tables). Irritating, but at least I can still create pushbuttons on the form itself.
There are other issues, but the main problems is that it appears that when I use VC with Web Dynpro I cannot trust the editor layout at all and the only way I can build something that looks decent is to fiddle about with field / form sizes and positions, checking every change on the output, until hopefully I get it looking ok. Having to do this will dramatically increase the time taken to develop VC applications. Has anyone else experienced these problems with VC and Web Dynpro? Has anyone managed to overcome them?

Thanks, but neither of these describes the problems I've been having. And they are misleading since they say that you can use VC with Web Dynpro only with Web Services ie not directly with BAPIs / RFCs, but using it with BAPIs / RFCs is one of the few things that works well in our system.
The most recent problem I've found is that if you make a form or table read-only it will stay read-only in Flash but the fields are editable in Web Dynpro. The individual field disable option does work for Web Dynpro, but it turns the fields from black to a vey pale and almost invisible grey (this doesn't happen in Flash). And you can't seem to change this.
It does seem to be a bit pathetic that input fields can't be made read only. I've tried expression boxes, which are read-only anyway, but they appear in as pale a grey as the disabled input fields. And although plain text fields can be added to tables, they are pretty useless since they can only hold a single value and so all the lines will contain the same value.
I guess I should resign myself to the fact that I am never going to be able to produce a decent screen using VC and Web Dynprp.

MDM with Web Dynpros

Hello,
I am new to MDM, Can anybody please let me know how could I use MDM with Web Dynpro's? I have read the article "MDM connectivity to java application" that could be the way to use if the sda are available!
Regards,
Dharmi

Dharmi,
This is excellent, in fact we are also working on a similar scenario. We already have developed some web dynpros which call the API's exposed by MDM and display the data. (Very soon we will write a blog on the same). However the problem is these web dynpro's become very specific with the respository you are dealing with. If that is all you want they that should be fine.
However, if you want to come iViews just like SAP then we mihgt have to think out of the box.
Have you seen the example of Applied.com? the back for these sites is SAP MDM. However these are the J2EE applications which are accessing the API's of MDM and also with other applications for placing the order.
The ideal solution that I can think of is to publish a catalog using MDM API's, give additional functionality of shooping cart, once everything is done, place the order which will create a sales order (SAP R/3 or any other ERP) via SAP XI (SAP EP communicating with SAP R/3 via XI.

Oracle as Back-end with Web Dynpro

hello
i wish to know how to use oracle with web dynpro as database store
initially we have been using R/3 system as our store with
backend of r/3 as oracle
but now we directly want to communicate with oracle

Hi Mitesh,
Initially I had tried few ways to connect directly from WD to Oracle, but nothing worked for me. Finally I could achieve it only through ejbs & even today I stick to that. I tried out many things for connecting directly including accessing the JDBC connector service of the server, but don't know why nothing worked for me.
Anyway, I'll send you the step by step process to create the ejb & use it in your WebDynpro application to connect to the database (you might find it a bit long, but I believe I have included every step). If someone knows a better way to connect pls let us know, cos it is tiresome to write ejbs each time we need to connect.
1)     Open the J2EE perspective
2)     Create an EJB Module project
3)     Right click on ejbModule, create a new EJB (select your EJB type)
4)     While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5)     Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6)     Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7)     Create an Enterprise Application project.
8)     Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9)     Right click on the EJB project, select Build EJB Archive
10)     Right click on the EAR project, select Build Application Archive
11)     Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
     Java Build path - select the EJB project from projects , check the selected project under Order & Export
     Project references select the EAR project
     WebDynpro references select sharing references tab, click add & make an entry as :     <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12)     Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
          Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
          MyEJB mybean = home.create();
          int a = 0;
          a= mybean.add(10,15);
     wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
Hope this helps & pls do let us know if you have any further queries,
Best Regards,
Nibu.

Search Help on Adobe Interactive Form with Web Dynpro ABAP

Hi All,
I have created Adobe Interactive Form with ZCI type and XML based interface type using Webdynpro ABAP.
I placed a text field USER_NAME on the form ( data element is linked to search help USER_COMP ).
Added Native WD UI element 'Value Help' to form to search for users and changed script
*var fieldName = "INSERT_NAME_HERE*"; to var fieldName = "USER_NAME";
The problem is that when I click on the value help button, nothing happens.
Is any more additional steps required ?

Business Graphics with Web Dynpro?

Hello @ all,
I have got a question about displaying dashboards and other charts on mobile devices using SAP Technology.
1) Does someone know, when it will become possible to display BusinessGraphics in Mobile Devices like BlackBerry, Pocket PC a.s.o buildt with Web Dynpro?
2) Which Technology can I use instead of Web Dynpro? Does it make sense to use HTMLB or should we use non SAP Products like "JFree Chart" for J2EE applications specially buildt for Mobile Devices?
Thank you for any hints!
Mehmet

Hi Memhet!
You can use Business Graphics with Web Dynpro with version NWDS 2.0(we are in was 6.40)and could be displayed on mobile devices.We use Symbol devices.I am not sure abt Blackberry.Is that your question? OR Are you looking for some alternate solution to WebDynpro.Is that because you have some limitations in running your WD applications in mobile devices?Just trying to understand......
Thx
