Hi All, Resolved. The WSDL file I was generating from contained soap12 artefacts. Though the JBoss wstools generated the mapping and java successfully, at run time the server log contained the warning WARN [org.jboss.ws.metada­ta.wsdl.WSDLDefiniti­ons] Multiple WSDL bindings referrence the same interface: Removing all the soap12 information from the WSDL and starting again with wstools fixed the problem.
