Try to move the MBeanListener class from inside the .war to inside the .sar.
Thank you very much for your reply.
it workds after moving the listener into .sar.
But My application in .war needs to get changed data from this listener.
How it accesses listener to retrieve the chnaged data?
You should still execute the same code in the .war, it just that the MBeanListener class should be loaded from the .sar file.
The .war code should have access to the .sar classes, I think.
Thank you very much, it works perfect right now.
