Hi,
I'm new to the MQ world.

We have MQ running on an AIX machine. I want to receive the messages
1. using the APIs.
2. using MDB.

I've done the ff:
1. Created a Q connection factory
2. Created a Queue
3. Created a listener

However, for the 1st scenario, I get the ff error:
Method createManagedConnctionWithMCWrapper caught an exception during creation of the ManagedConnection for resource jms/b2bqconfactory, throwing ResourceAllocationException. Original exception: javax.resource.spi.ResourceAdapterInternalException: createQueueConnection failed

For the 2nd scenario, I am not able to start the listener.

I'm sure I'm missing something.
Pls help

tx in adv

What do you mean

Quote:

1. using the APIs.

Stand alone java programs ?

Where did you store the JNDI definitions.

I'm trying to connect using the IntialContext and JMS API. Here's the code.

initCtx = new InitialContext();
QueueConnectionFactory qcf = (QueueConnectionFactory)initCtx.lookup("jms/b2bqconfactory");
QueueConnection conn = qcf.createQueueConnection();
QueueSession session = conn.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue q = (Queue) initCtx.lookup("jms/b2bqueue");

QueueReceiver receiver = session.createReceiver(q);
Message msg = receiver.receive();

For your stand alone program, you'll find plenty of examples at:

http://www.developer.ibm.com/isv/tech/sampmq.html

I'd suggest starting with one of these.

Queue q = (Queue) initCtx.lookup("jms/b2bqueue");
QueueReceiver receiver = session.createReceiver(q);
//before you can receive anything you must start the connection
conn.start();
Message msg = receiver.receive();

Don't forget to close the receiver, close the session and close the connection once you are done.

Enjoy
