Any chance I can get the IDL for that simple service in the tar. I'd like to create a pure CORBA client and server for it like we have for the CORBA demos. That should help narrow down where the problem is. If the client can talk to the pure CORBA server, we know the problem is in the reading/unmarshalling. If the pure CORBA client can talk to the CXF server, we know the unmarshalling is OK. If nothing can talk to anything, we're really screwed. :-)
At the very least, it would help narrow down where the problem is.
