We have the same problem using ejb3 over http with jboss-remoting coming along with jboss4.2.0. We also get the right exception when making calls over rmi but getting UndeclaredThrowable caused WebServerError when making the same calls using http as transport. Any solutions to this? Is there a configuration needed on the server side? regards /sandor/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064949#...
