JAX-WS和sun-jaxws.xml

Question

I have read a lot of posts on public forums about deploying JAX-WS on different servet containers and I have following questions/queries based on that.

Following is my understanding :

1) sun-jaxws.xml is required ONLY BY Sun's RI (metro project) since com.sun.xml.ws.transport.http.servlet.WSServletContextListener class needs it. (looking at source for this class , it reads this file from hardcoded location).

2)It is also required if servlet container is not Java EE 5 compliant.

3)Different application servers like Jboss , GlassFish can use their own JAX-WS implementations (like Apache CXF,Metro )

So my questions are :

1)If I use Sun's RI (metro) on Java EE 5 container like JBoss or GlassFish , do I still need to use sun-jaxs.xml ?

2)If I develope JAX-WS web service on Java EE 5 container like Jboss , can it be portable to another Java EE 5 container like GlassFish. What I mean is can I deploy the war as it is on another container ?

Please help me sort out above queries since I am really confused about Sun's RI and sun-jaxws.xml descriptor usage.

Answer 1

Application servers have own web service client frameworks. You can think these are like jaxws. When you deploy an app to app server default option app server use own framework for web service call. Therefore if server need a configuration file like as sun-jaxws.xml you must put it relevant directory. But I dont think you need it.

Second option is configuring the app server for using your third part jax-ws library. It is an extra option. For example I made in WAS. Because of that when you choose this choice you must use sun-jaxws.xml

Hopefully I have been clear in my answer :)
