title: Eclipse WAS V7.0 Dev Tools wsimport error
body: <p>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:</p>

  <p>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.</p>
  
  <p>Do you guys have any idea why I'm getting this error? Any help would be much appreciated.</p>
  
  <p>Thank you,
