Yeah this is because it was added as part of the JAX-WS spec. The current 1.x versions are using the original JSR-181 spec which was based on JAX-RPC. We will be releasing initial JAX-WS support in our upcoming 2.0.0 beta2 release if you want to give it a shot. I will post with more details and instructions once it's released. -Jason View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3982438#...
