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;


/**
 * TODO: Documentation to be done for type 'TelNetMBean'..
 *
 */

public interface TelNetMBean
{

 /**
 * This method is one of the life cycle method of MBean, will be invoked automatically while starting this service.
 *
 * @throws Exception
 */
 public void start ()
 throws Exception;


 /**
 * This method is one of the life cycle method of MBean, will be invoked automatically while stoping this service.
 *
 * @throws Exception
 */
 public void stop ()
 throws Exception;


 /**
 * This method is used to set the port of the TCP\IP server by JMX console.
 *
 * @param aPort
 * @throws Exception
 */
 public void setPort (String aPort)
 throws Exception;;


}
