Hi Richard, I asked you to try with the release jbossws-2.0.0.GA to prove that .net webservice is functioning normally and that the problem is in release jbossws-3.0.1-native-2.0.4, because the release jbossws-2.0.0.GA works. The .net webservice return always http code 200 to correct request. You got error 500 with release jbossws-3.0.1-native-2.0.4 is a problem too.
