But what if I'll be using CXF with Apache plugins ? I mean org.apache.cxf:cxf-rt-frontend-jaxws. What would be the implications ? I would replace the JBossWS stack in the server with the CXF one and continue like this. This is because, after having ran wsconsume and deployed the generated war, there is no web service deployed. The generated stuff includes, besides the JAX-B classes, the SEI and a *Service class that I'm not sure what it is as it is annotated with @WebServiceClient. There is no *Impl class, as it would be the case with CXF, and I tried to implement it from scratch but I cannot see any deployed web service in the console for this war. It doen't seem to exist any documentation about doing contract-first with JBossWS, as oposed as the CXF documentation which is very complete. What do you think about this approach ?
