Web Dynpro, how to consume web service

[Former Member]

Hi Experts,

I am developing a web dynpro app and I want to create an adaptive web service model. I am using JDI.

I created an EJB module-DC in which I have a Session Bean which accesses an Entity Bean. I want to use the Session Bean as Web Service. But when I create a web Service from the EJB-module-DC and deploy the corresponding ear-DC I can't see the Web Service in the web service navigator? And I also can deploy this project only one time, after that I get an exception thrown. What could be wrong?

If I am using jdi do I have to use a deployable proxy dc when I want to use a web service??? I tried that, too, but I if I do so, I can't use it as adaptive web service model and have to look it up with jndi, is that correct?

I am a bit confused about the web service scenario and JDI. If I deploy a normal ear project with a web service (not a jdi dc) I can find the web service in the web service navigator of the j2ee engine.

Any help is appreciated

Hi Ayyapparaj,

yes I have checked this and I proceed as described in the doc of your first link. But I get the following exception when I want to deploy the Session Bean including the Web Service:

Deployment exception : The deployment of at least one item aborted

I already deleted the ear from the engine and tried to redeploy but no success.

Deployment works for the first time. But I can't see the web service in web service navigator or in Visual Admin. If I want to redeploy (e.g. if I made any changes), I get the exception again. What is the problem?

Hi Manuel,

First test your webservice whether its working fine or not.Then test the application.

Hi Mithu,

that's the problem. I think my web service is not deployed correctly, because I can't find it in visual admin or in web service navigator.

I could solve the problem.

The error was that the packagename started with "com..." When deploying, the package is temporarily copied in a "com" folder. But my package already starts with "com". So the temp folder is named "com1", which is not supported. This was told to me by a SAP expert.

When the package doesn't start with "com" everything works fine.

So problem solved.
