I deploy an EJB jar that contains webservices.xml, jaxrpc-mapping.xml and a WSDL file, and JBoss throws the following exception.

If I deploy the same bean (which only has a 'hello world' method) as a remote bean, I can use it just fine.

Where do I turn on verbose debugging? How can I tell from this message whether it is a problem with my code or with the web services code in JBoss?
