R2203 of the Basic Profile standard (http://www.ws-i.org/Profiles/BasicProfile-1.2.html) states: 'An rpc-literal binding in a DESCRIPTION MUST refer, in its soapbind:body element(s), only to wsdl:part element(s) that have been defined using the type attribute' where you say: <wsdl:message name="HelloWorldIn"> | <wsdl:part name="HelloWorld" element="tns:HelloWorld" /> | </wsdl:message> in rpc-literal it should be <wsdl:message name="HelloWorldIn"> | <wsdl:part name="HelloWorld" type="tns:sometype" /> | </wsdl:message> Axis I noticed is lenient on this rule, but JBossWS seems pretty strict about it.
