    jboss 4.0.2 Webservices dynamic proxy client issue :  could

    Henry Jones Newbie


      Hello,
      I'm in a bit of a bind.
      I'm working with webservices in jboss 4.0.2.
      Trying a simple test at first.
      I've successfully deployed a webservice.

      However I have a problem when trying to access it using the a Dynamic Proxy Client. The problem
      happens when I use a complex type.

      I get the following exception:

      java.rmi.RemoteException: null; nested exception is:
