WebSphere Platform 6.0 [ND 6.0.2.31 cf310840.03]  
Java version = J2RE 1.4.2
Host Operating System is AIX, version 5.3
we are using websphere 6.0 and we have installed a new JVM. When I try to deploy the war file, its gets installed fine. I do see any expections while the deployment of the application happens.

When I bring up the server i notice that the application fails to start during start up. I notice the following exception
