It happens too on JBoss 3.2.3. Has anyone had more luck with this? It amazes me because this should have been something simple that turned out to be a mysterious problem... but then again, it's always like that :)
I am getting the same error 400 in the browser and Mapping configuration error on the JBoss console. I am using JBoss 3.0.4 with Tomcat 4.1.x.
Please can anyone give me some clue as to what's happening here!
