Hello,
I'm trying to migrate my application from Jboss 4.2.2 to Jboss 5.0.0 GA. My
Application is like that, it has a MBean which initiates some threads that keeps listing
to some socket, along with that, it also has a MDB, which needs to perform some task on
receiving some messages from my another application.
Now the problem is that, when I try to deploy the existing application on this new AS (
5.0.0 GA), MBean is not getting deployed, along with that, MDB gets deployed, but still it
is not visible in JMX console.
But, the same application is working fine on Jboss AS 4.2.2.
Following is the code:
package com.barco.cms.tcpip;

|
| /**

Is there any backward compatibility issue with AS 5.0.0 GA, or I'm doing some thing
wrong.
