Can you please provide more info on your packaging / web.xml (if present) ?
Basically, what happens when spring support is used is that the address you provide there in jaxws:endpoint is supposed to match the path for the actually deployed endpoint. So, you could probably use "/helloWs" there, but that would be your app context root is "helloWs" and the url pattern is "*".
Do you really need the jbossws-cxf.xml ?
I am not sure which JBoss AS you are using. If it is JBoss AS 5, then including this file is not a mandate unless you need some more fuctionality apart from knowing the details regarding the deployment endpoint.
When you do not include this, in your /tmp folder, the jbossws-cxf.xml file gets automatically generated with the required configuration.
