The first Beta release (JBossWS 5.0.0.Beta1) was tagged in September last year; it brought Apache CXF 3 series in JBossWS / WildFly and eventually dropped JAX-RPC support ;-)
JBossWS 5.0.0.Beta2 was tagged a couple of months later and featured improvements in the pre-defined client/endpoint configuration area and the options for declaring Apache CXF interceptors through simple configuration properties.
The latest Beta release so far, JBossWS 5.0.0.Beta3, has been tagged and integrated in current WildFly master last month; the most notable change in it is the completely new build and testsuite framework, which now fully relies on Arquillian and ShrinkWrap for WS endpoints testing.
More interesting additions, in the direction of enabling configuring Apache CXF proprietary features without recurring to Spring descriptors, have already been implemented and are coming soon.
Now, you're welcome to go, checkout JBossWS 5.0.0.Beta3 tag and play with it. Or you can simply hack on the latest WildFly master. (also note that WildFly 9 Beta1 is being released very soon!)
Alternatively, you could also play with another recent WS release, the 1.1.0.Beta1 version of the our jaxws-codefirst Maven Archetype, which has just been moved to rely on JBossWS 5 Beta artifacts. You can read about it in a previous post of mine, but it basically boils down to simply using the following command line to kick start a WS project in few seconds:
mvn archetype:generate -Dfilter=org.jboss.ws.plugins.archetypes:
That's all for now, stay tuned, JBossWS 5 is coming... :-)
