Hi!!
I've a problem: I want to create a listener on a queue that notify me when a message arrive, using Java but not JMS.
Setting waitInterval to infinite doesn't resolve my problem: when I do a get on the queue I've the reason code 2033, no message on the queue.
How can I do it?
I hope you understand my problem, and I thank you in advance. |

If the wait-interval is infinite (-1), then you can't get a 2033.... show us the relevant code....

Hi!
Here there is the code:
try {
MQMessage rcvMessage = new MQMessage();
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.waitInterval = MQC.MQWI_UNLIMITED;
queue.get(rcvMessage, gmo);
}
.....
If the queue is empty the exception is:
MQJE001: Completion code 2, Causa 2033
com.ibm.mq.MQException: MQJE001: Completion code 2, Causa 2033
at com.ibm.mq.MQQueue.get(MQQueue.java:1033)
at routing.RoutingThread2.run(RoutingThread2.java:61)
Can I listen on a queue (for example with a thread) until a new message is putted on without this exception?
I thank you once again,
Dario
Sorry, you need to ALSO set:
gmo.Options = MQC.MQGMO_WAIT;
Can you post this info to the forum so others can learn what the problem was? Thanks
