in my opinion, developers of Netbeans are waiting for complete version of JBoss 5.0 (with JAX-WS 2). I don't know why this situation exists so long (since JBoss 4.0.4). I'm maintainer of pretty big web application which exposes web services. This app. was deployed on JBoss 4.0.3 (with JAX-RPC). I have a problem with changing my application server to new version of JBoss.
