We shifted our application to Jboss-4.2.2GA version, from Jboss-3.2.8SP1 version. We have virtual instances instances of jboss running. Problem here is, in jboss 4.2.2.GA, a jar file abc.jar in .../WEB-INF/lib is not getting deployed properly. I get a ClassNotFoundException. Surprisingly, if I put the same jar file in the lib folder of the virtual server instance directly it works fine. We've the same ear deployment in Jboss 3.2.8SP1, it works fine without any issues.
I just wanted to know if this issue is specific to jboss 4.2.2.GA? Any loopholes in it?
