Hi, I had download the JBoss 4.2.1.GA and installed it.
If I want to try the web services using JAX-WS follow this tutorial: Web Services (JAX-WS) in Java EE 5 http://www.netbeans.org/kb/55/websvc-jax-ws.html, does the JAX-WS need to download and install?
There is "some" support for jax-ws in 4.2.1, but if you want full support you must upgrade the jbossws component to a 2.x (from 1.2.x). Ask in the webservices forum.
