[jboss-user] [Messaging, JMS & JBossMQ] - Multiple innvocation for single object(Message) in Queue
Hi Guyz,
I have a MDB running in two machines A and B, Queue is common for both MDB's.
Queue is residing on Machine A.
I posted 5 Objects(message) (eg. Obj1, Obj2, Obj3...Obj5) from Java client to Queue.
The onMessage part is designed to consume 2minutes for execution.
Both MDB's are consuming messages parallel, but the consumed Objects(messages) is
repeatedly picked up for execution by MDB's even after completion of the consumed
message.
Pls suggest the working pattern of the MDB message handling.
Jboss Version 4.0.3.
public void onMessage(Message msg){
System.out.println("OnMessage is called............."+getTime());
String countId="";
try
{
ObjectMessage objMsg = (ObjectMessage)msg;
Count objCount = (Count)objMsg.getObject();
countId=objCount.getOrderNumber();
System.out.println("Message Received***********:"+countId);
for (int i=0;i<5000;i++ ) {
for (int j=0;j<9999999;j++ ) {
;
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
System.out.println("OnMessage is End
process........."+getTime()+"*******"+countId);
}
