According to the current docs stateful webservices in JBossWS are done differently (its usage of addressing) than what is specified in the JAX-WS 2.1 spec, the 2.1 leverages the annotation javax.xml.ws.soap.Addressing annotation (I think that is the big difference between 2.0 and 2.1) Do you guys think that JBossWS should move towards 2.1?
