I suggest you upgrade to 1.2.1 and consult the userguide. JSR 181 was actually a preview impl. in 1.0.4 and is feature complete in 1.2.1
Thanx for you reaction, I've downloaded jboss-4.2.0 CR2. jbossws-1.2.1.GA is included there. I'm halfway now and have found out that with 1.2.1 no xml is needed (besides web.xml) which is very nice and a lot better than jaxrpc.
