I've got
client -> EJB -> MBean -> EJB
1 2 3 4
this works fine when 2, 3 and 4 are all in the same
thread, but when I have the MBean create a new thread
I get NullPointerException (stack trace is below) trying
to call my EJB through a local interface.
I'm using an MBean so I can create a thread to have
things run asynchronously in JBoss. Is this not
the right way to design this? Should it work?
JBoss 3.0 Beta
Linux
JDK 1.4
Thanks!
