Any words about this issue? Do I have to change "jbossws.beans" as the only way to do this?
Yes its currently zipped, we will explode it in the next update.
The reason it moved from jboss-service.xml is to support decoupling from JBoss Application Server. jbossws.beans is a jboss microcontainer deployment which can be bootstrapped in other environments (provided there is the appropriate integration layer written).
