EEZEAR will not start after enabling WAS security. The SystemOut.log shows :
WSVR0206E: Module, EEZAAB.jar, of application, EEZEAR.ear/deployments/EEZEAR, failed to start
The most common reason is that Java 2 Security is enabled. The EEZEAR app will
fail to start if it is enabled. Note that Java 2 security will be
automatically enabled when you enable WebSphere security in the
Integrated Solutions Console.
Resolving the problem
Disable the Java 2 Security option, from within the ISC and recycle the WAS server.
