    Problem with methods returning an attachment

      I have a nasty problem.

      Some methods of my web service should return an attachment.

      I start with a handwritten WSDL file and generate the necessary artifacts and descriptors using JAX-RPC tools.

      There are no warning or error messages at deploy time.

      An error occurs after invoking the method:
      16:27:34,485 ERROR [SOAPFaultHelperJAXRPC] SOAP request exception
      org.jboss.ws.WSException: Operation does not have a return value: {http://myservice.mycompany.com/myservice}getTemplate

      I can't figure out why JBoss behaves that way - can somebody help me with this?

      Thanks,

      Bernhard
