JBossESB 4.2GA will expose webservice endpoints through the JBossWS 2.0.0GA Webservices stack (due to release in early July). There'll be no support for exposing Axis hosted endpoints in JBossWS 4.2GA.
WRT WS-* specs... check the JBossWS docs.
There's a good chance that later versions (later than 4.2GA) will support JBossWS2.1.0, at which point we'll be able to expose Axis (and other) webservice endpoints. Nothing concrete on that as yet though.
Are there any examples of how to set up the ESB to handle web service communication north bound (as web service exposer) and south bound (as web service consumer)?
Check out the following quickstarts:
webservice_war1 - exposes a 181 WS
webservice_jbossws_adapter_01 - an alternative way to expose a 181 WS
webservcie_bpel - demonstrates consumption via the SoapUI action
We are working on the docs and better examples now. You should see more in the next 4 weeks or so.
We should be able to sort out your questions in the forums for the short-term.
