Hello, I am studding ws addressing right now and I thing I have the solution for the two times clientid. You have to delete line outProps.initializeAsReply(inProps, false) in org.jboss.test.ws.jaxws.samples.wsaddressing.ServerHandler.handleOutbound. The reason is that this line is called afterwards in org.jboss.ws.extensions.addressing.jaxws.WSAddressingServerHandler.handleOutbound.
