The Jboss.NET works, and is really easy and very quick to deploy if using the xdoclet-jboss-net module (just add a little bit to your existing ejb/business code and go). But you'll have to talk to the dev's about how easy/impossible it will be to migrate webservices from Jboss.NET to JBoss4/WS4EE.
Thanks for the reply. We've considered moving to Jboss 4.0 to take advantage of JbossWS, but are not certain when the production release date is. Anyone know for certain?
The JBoss-4.0 release is due within the next couple of days. Ease of development is probably not your only concern. How about interoperabilty, performance issues?
I'd be interested too which SOAP stack works best.
