We generally support JAXWS deployments as OSGi bundles. The internal WS stack is CXF. When it comes to usage of some propriatary CXF feature I cannot say however. We would need a test case that isolates the issue - then we could talk in the context of that. A good starting point is https://github.com/jbossas/jboss-as/tree/master/testsuite/integration/osgi/src/test/java/org/jboss/as/test/integration/osgi/jaxws.
