Hello !

I am trying to get all the messages in the queue at once. For that i use getCurrentDepth to determine if there are any messages in the queue.
Here's the code:

Code:
int depth = q.getCurrentDepth();
while ( depth > 0)
{
           q.get(message, gmo);
           msgText = message.readUTF();
           System.out.println("Msg: " + msgText);
           depth--;
}


And here's the output

Msg: Platon#Daniel
Unable to load message catalog - mqji
Exceptie aruncata de MQ. Completion code 2. Reason code 2033. Have a nice day !
com.ibm.mq.MQException: Completion Code 2, Reason 2033
at com/ibm/mq/MQQueue.get (MQQueue.java:493)
at GetMSGS.<init> (GetMSGS.java:35)
at GetMSGS.main (GetMSGS.java:57)

Same thing happens when I put
Code:
while (q.getQueueDepth() > 0)
{
    ...
}


What is the problem ? The getCurrentDepth() prints fine.

Thanks,
DAN

Quite simple.
The Queue is empty (2033) and you aren't handling the exception.
Wrap it in a try catch. If the reason code is 2033 dont let the program bomb out.
