we are using jboss-4.2.0.GA , internal gigabit network
usually we have deployed 3 jboss, all in a cluster, and it works perfectly
and recently, we have deployed more jboss, but in a different cluster (i.e.
using a different cluster name), and find that the broadcast packets in the
network

transaction = container managed, REQUIRED
using jboss-spring interceptor to inject dependencies (e.g. the hibernate dao)
to the session bean
we are using ejb 3 stateless session bean to wrap the hibernate codes to do
database CRUD
(just simple hibernate,

for normal situation, our ejb client (tomcat) can connect to jboss server
successfully
e.g.
we have 3 jboss in clusters, we are using ejb 3 stateless session bean
(clustered),
when one jboss is down for deployment, and up again, the client can reconnect
to this jboss again

let me describe my situation with some simplification:
(jboss4.2.0.GA, ejb3)

now i updated the session bean code

Is there any documentation/reference about the MBean details under
jboss.management.local?
I can get the statistics of stateless session bean from your guideline (from
the other thread by following the source code of twiddle), but I also want to
know the complete reference of the details of
From the web-console, I can see the Invocation Statistics of each EJB
