mbean not found error when upgrading from 4.0.1sp1 to 4.2.3.GA

[mrfixit440]

I have a mbean I create in one war that I try to access in another war.  This works in 4.0.1sp1 but the mbean isn't found in 4.2.3.GA.  Has something changed between versions?

I don't get no startup errors so I guess in 4.2.3.GA, mbeans are scoped to be seen only from their respective war file. Another thing, I couldn't see the mbean in jmx-console.

Anyway, I solved this problem by packaging up my mbean in a .sar file and having a startup servlet in my war connect to its MBeanServer and invoking start on it.  This worked.
