Andreas,

Can you please post the generated code? ZukoProxy.java and ZukoSoapBindingStub.java?

thanks,
dims

Here is the generated code of the client.
I'm sorry for the lack of formating, for some reason the code tag does not work for me.

Andreas,

* Can you try the following piece of code to see if you still get the exception?

fon.ws.wsi.zukoClient.Zuko zuko = (new fon.ws.wsi.zukoClient.ZukoServiceLocator()).getZuk o();
String endpoint = (String)((javax.xml.rpc.Stub)zuko)._getProperty("javax.xml.rpc.service.endpoint.address");
System.out.println(endpoint);

* Are you changing the class loader policies? parent-first / parent-last?
* Do you possibly have a jar that has a javax.xml.rpc.Stub somewhere in your environment?

thanks,
dims

Issue solved!

RAD placed a jaxrpc.jar into my webinf/lib without my notice.
This jar contains the class javax.xml.rpc.stub, which is mentioned in the exception.

I removed the jar, and everything works fine now.

Thanks a lot for your help and kind mails, dims!

Andreas
