I'm using JBoss 4.2.2 GA with EJB3. My Client is a SWING-Client and I accessed the Server as described in http://www.jboss.org/community/docs/DOC-9049 with HTTP Connector! Now, I throw an Runtimeexception("Versionerror by update") in my SessionBean and I want to show this Messsage on my Client. But I get only a Undeclared Throwable Exception with a WebServerError inside. There is no way to get my original ErrorMessage from the Server. I've added RETURN-EXCEPTION = true parameter in ejb3-deployer/meta-inf/jboss-service.xml but the result is the same! What is to do?
