Web Dynpro tutorials

Hi everybody!
Long time ago the last time I was programming Webdynpro for Java I had found many tutorials how to create my Webdynpros. There was also a matrix where I could choose the different tutorials (about 20 tutorial). Unfortunately I can not find them any more on SDN.
Pretty sure that someone can help me. Of course I will award.
Bye Markus

Hello singer,
you could check in sdn aswell if not that matrix tutorials look at individual ones you will find all those individually ....
these documents have sample applications and study materials too....

JCO Connection for web-dynpro tutorials (EP 6.0 SP9 downlaod from SDN)

Hello,
I have a question regarding JCO connections for web-dynpro example/tutorials. I have installed WAS 6.40 sneak preview from EP 6.0 SP9 download from SDN. Installation instruction says: Choose "No SLD available"
but the web-dynpro example/tutorial asks to create JCO connections by going to web-dynpro -> content admin..etc on http:<host>:50000..Here, all the tabs relating to creating JCO connections appear to be "protected" on my screen. so I can't do anything further. By going to http:<host>:50000/sld, I also tried to add SLD server..but that is not helping. There is some "import" button, but which CIM file (in which folder etc) am i supposed to import for a simple test system? What are the steps for a bare minimum setup so that I can use the WAS 6.20 system at work-place as my backend & try out the web-dynpro examples? Do I really need SLD setup? Where is documentation about all this after one installs the WAS 6.40 JAva? I was expecting it somewhere at least in the eclipse IDE help-documentation..None of the web-dynpro tutorials explain this !
thanks

Thanks everybody.
NagaKishore, after doing all the steps, when I goto
localhost:50000-> web dynpro -> content administartor, and try to "maintain JCO Destinations" I am getting this error: (full stack trace not included)
An error has occurred:

Hi Valery,
thanks for this great idea. Indeed, there is no channel set up to communicate feedback/suggestions/questions to Web Dynpro tutorials or articles in a standardized way.
WebLogs can be commented on the WebLog page itself and they are announced in a special ;\ New Web Dynpro Weblogs which can be opened via the <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d">Web Dynpro Feature2Sample Matrix</a>. Actually the section 'Further Information' lists all related articles, WebLogs etc. These links are regularly updated so that the Sample Description Pages helps to keep all links to valuable information in a central place.
The 'Sample Description Page' should additionally comprise a section <b>'Discussion'</b> with a link to the above 'Article Comment Thread' in the Web Dynpro forum. The reader downloads the material from the sample description page and also finds a link to the related 'Article Comment Thread' there.
For all new articles (which are combined with a related 'Article Comment Thread') the <i>Further Information</i> links could point to the 'Article Comment Thread' (which then itself links to the article) but not directly to the article resource. The reader can then also have look at the existing comments to the related resource. As an alternative the article PDF itself should have a permanent link to the 'Article Comment Thread' in the Web Dynpro Forum.
Please post your comments on this idea.

Web Dynpro Project Reference

Hi all,
I am working with DTR and I'm trying to figure how to configure DC references correctly. The DCs I have are:
1. EJB module DC that contain a session bean.
2. Java DC that uses the EJB module (#1)(client)
3. Web Dynpro DC that uses the Java DC (#2)
4. EAR DC that deploys the EJB module (#1)
I tried to add the Java and EJB DCs as used DCs for the Web Dynpro DC, but this doesn't seem to work.
How exactly should I define the used DCs (run time, design time, deploy time soft/hard etc? Do you know of any documents that describe how to do it (I found a tutorial in the Web Dynpro tutorials that explains how to use an EJB from web dynpro, but it didn't address any issue regarding DC references)
Thanks in advance,
David

Hi David,
which part exactly "doesn't seem to work"?
- Are you able to select the DC to be "used"?
- Does the used DC appear in the list after you added it?
- Or do you only have problems at runtime? (The Sharing reference should only affect runtime (!?) )
I'm not sure which DC should be referenced from where, but do you get an error message, or does simply nothing happen, when you create a use dependency to the other DC?
I had this problem several times. When I created a dependency nothing happened and after a few more tries the dependency suddenly was created and shown in the list of used DCs.
This is just another suggestion. Maybe it is really not possible to reference DCs the way you try.
Regards, Alex

How Can I convert or include a Transaction to ABAP web dynpro

Hey,
Im new to web dynpro, and I have followed sap web dynpro tutorials step by step but I couldnt find a way to create an interface the same way I create screens. Can anyone tell me how do I design an interface in web dynpro or is there a way to convert my transaction to an ABAP web dynpro application?
Thanks.

No there is no way to convert your gui based screens to web dynpro, you have to design them in web dynpro. And the design of WD is not like normal screen painter(SE51).
What I would suggest you is first go thru some basic tutorials, then you will get the idea of UI elements which are used in WD.
Have a look on this link

Can you please suggest me how to create a user in UME Database using web dynpro java custom application.
My Requirement is user can register his/her user id in SAP Portal 7.3 UME database.
Please suggest me.
Thanks and Regards,

Hi Amit,
Generated Documentation (Untitled)
This is what you're looking for, there's no real cook-book -- though Amey mentioned there might be some material on SDN, perhaps some tutorials.
You should be looking into com.sap.security.api.IUserFactory, methods newUser(String) which gives you and IUserMaint and commitUser(IUserMaint, IUserAccount) -- IUserAccount can be obtained using com.sap.security.api.IUserAccountFactory, method newUserAccount(String)
Hope it helps,

Source code for "Creating an Extended Web Dynpro Application"?

Hello!
I'm a rookie in the field of SAP Netweaver and I'm justing getting started with some tutorials. My problems with "Creating an Extended Web Dynpro Application" are to massive to be posted on this forum in this stage. What I want to have some help with is to find the source code for that tutorial so I can get som guidence from there.
Following text is cut out of this page:
http://help.sap.com/saphelp_nw70/helpdata/EN/5d/f42fef2eec724597a03b6bcc670c2c/frameset.htm
Creating an Extended Web Dynpro Application
You can download the Web Dynpro project for the current tutorial from the Software Developer Network SDN (http://sdn.sap.com -> Web Application Server -> Web Dynpro -> Sample Applications and Tutorials) in two versions: one skeleton version you can use for exercises and one final version (solution) for an immediate build, deployment and run on the Java engine of the SAP Web Application Server.
How hard I try I can't find the specific source code on sdn.sap.com
Does anyone have a clue where it is?
Thanks!

Hi!
I did what you said but I seem to miss the IDE folder. This is what it looks in my Explorer
C: > Program Files > SAP > IDE > CE > eclipse > (no folder called "examples")
I also did a search in this eclipse folder for "examples" but I did'nt find the example I'm looking for
I am running a newer version of NWDS:
SAP NetWeaver Developer Studio
SAP NetWeaver 7.1 Composition Environment SP03 PAT0000
Maybe that's why things don't look the same?

Web Dynpro ABAP in SAP E-Recruiting

Hi,
We just imported SP8 for our SAP E-Recruiting 6.0. SP8 offers Web Dynpro ABAP as candidate UI. One question we have is how WD pages incorporated for recruiters who still use BSP pages. For example, when a recruiter logs into E-Recruiting and finds a specific candidate, he/she can click on "Candidate Profile" to get to that candidate's pages. In BSP technology, recruiter actually uses exactly the same pages that candidate uses for Work Experience, Education, etc.. With candidate UI using WD technology, does recruiter use the same WD pages when displaying candidate profile information? I have been searching all the possible places, such as IMG, SICF, in order find a spot so that I can set the switch on, but so far unsuccessful.
Any help is greatly appreciated.
Li

Hi Li ,
At best of my understanding in WD ABAP , its possible to make one WebDynpro page serving same purpose ( showing profile deatils ) visible for manty( Candidate , as well as Recruiter ) ....
I would like to know what exactly you want from web Dynpro ..then I will be in better position to tell you.
FYI ...
1) Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
2 ) I can give you links that can help you a lot.
First of all start doing SAP SDN tutorials .
Create some compenents with BAPI , Component usage and ALV .
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/02e1fa45-0801-0010-10a0-f1cf47e8c943
/people/marilyn.pratt/blog/2005/12/20/web-dynpro-for-abap
Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .
Wait not just that SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )
See packages like SWDP_DEMO , SALV_WD_DEMO
there are many more .

Using a Deployable Proxy in a Web Dynpro Application

Hi,
We have a Web Dynrpo application whose model is built from a set of Java business objects (POJOs.) These Java business objects currently make calls to a back-end R/3 system using JCo. We would like to provide the ability to allow the calls to be made over Web Services to the back-end system.
To call the RFMs as web services we have created a Deployable Proxy project, added the proxy as a public part, then referenced that public part in the web dynpro application. At this point we can write code to call the web service that looks something like:
InitialContext ctx = new InitialContext();
Object serviceObject = ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSService service = (Z_MRDM_GET_PLANTSService)ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSPortType port = service.getLogicalPort();
Z_MRDM_GET_PLANTS plantParameter = new Z_MRDM_GET_PLANTS();
plantParameter.setI_PLANTID(id);
plantParameter.setI_PLANTNAME(name);
Z_MRDM_GET_PLANTSResponse response = port.z_MRDM_GET_PLANTS(plantParameter);
MT001W[] plantArray = response.getET_PLANTS();
The problem is that when I call looup to retrieve the service implementation I get a ClassCastException.
The tutorials for using a proxy in web dynpro all assume that the web service is what the model is based upon but that's not possbile for our scenario we need to call the proxy from the business objects which are the basis for our model.
According to the help documentation for consuming a deployable proxy in a JSP page:
<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm">http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm</a>
It discusses adding JNDI mappings. Is this what's needed for the reference to work in a Web Dypro application too? If so, how would one add the JNDI mappings references to a Web Dynpro application?
Many thanks!

Hi Dheeram,
I'm not certain about JSPDynpage specifically, but in a general J2EE Enterprise Application project you can add a reference to the application-j2ee-engine.xml file. For example here's the content of an application-j2ee-engine.xml file that references a proxy:
