I've been using Axis and JBoss together for a few months, with mixed results. I'm using the java:EJB provider to connect to stateless session beans.

On a fresh server restart everything works great. However, after redeploying the ear file, I almost always experience:

13:46:30,112 ERROR [org.jboss.web.localhost.Engine]

JBoss' classloading schema is infamous for it's eccentric behavior. Has anyone else experienced the same problem, and if so, do they have a solution. It's annoying to have to restart my server after making a minor change and redeploying.


Use JBoss.NET from the "all" configuration and the associated XDoclet tags and everything should be okay. :-)
