Eclipse WAS V7.0 Dev Tools wsimport error

Question

I'm trying to generate a "Top down EJB Web Service" implementation from a WSDL with WAS V7.0 Developer Tools. (Server runtime WAS 7.0, web service runtime IBM WebSphere JAX-WS.) After selecting my EJB and EAR projects and specifying further options, I always get the following error, regardless of my options:

Errors occurred during wsimport.

Going through the exact same steps in Rational Application Developer 7.5.1, I can successfully generate an EJB web service implementation with an HTTP router module for my WSDL. So I think this problem might be related to WAS Developer Tools.

Do you guys have any idea why I'm getting this error? Any help would be much appreciated.

Thank you, Csaba

Make sure you are using the WAS 7.0 JVM when you run the wsimport. You may have several JVMs on your workstation. The JVM under <was install>/java is the one you want in your PATH ahead of all others when using the command.
