The receive exit interface allows you to examine, and possibly alter, the data received from the queue manager by the WebSphere(R) MQ Client for Java(TM).

class MyReceiveExit implements MQReceiveExit 
  {
      // you must provide an implementation of the receiveExit method
      public byte[] receiveExit(MQChannelExit       channelExitParms,
                                MQChannelDefinition channelDefinition,
                                byte[]              agentBuffer)       {
          System.out.println("I'm here :)"); 
          return agentBuffer; 

      }
  }

public static void main(String args[]) { 

       MQEnvironment.hostname   =   "HOST"; 
       MQEnvironment.port      =    1414 ; 
       MQEnvironment.channel   =   "CHANNEL"; 

       try { 

            MQEnvironment.receiveExit = new MyReceiveExit (); 
           MQQueueManager qmgr = new MQQueueManager("tempQM"); 
   ...
