No no - that's not what I meant. The web requests have nothing to do with processing of JMS messages. The web front-end simply allows users to look at the orders that have been received via JMS. Also I am not creating a MessageListener every time a message arrives. I am simply creating a pool of message consumers on application startup so that multiple JMS messages can be serviced simultaneously. So the code below is executed only once when the web application starts up:

connection = connectionFactory.createConnection();

for (int i=0; i<concurrentConsumers; i++) {
 Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
 MessageConsumer messageConsumer = session.createConsumer(destination);
 messageConsumer.setMessageListener(messageListener);
}

You are right. I am trying to avoid JEE myself. EAR comes with lot of baggage that I don't need. Also development cycle slows down.

I want to try that anyway - just for my understanding. So how do you get a non JCA RA connection? Using an initial context lookup?

Couple of follow-up questions:

1) The InVM instance that I have in my JBoss AS - is it also exposed on a url (such as jnp://localhost:1099)? In other words, can a standalone client access it by looking it up using jndi?

2) Instead of an InVM instance, if I start HornetQ as a standalone server, can an MDB listen to it? How would a connection factory be configured for this use case?

Thanks.

Thanks for the pointers Tim. The Wiki article was excellent - clarified bunch of concepts for me.

Any other lookup than java:/JmsXA - The one at java:/JmsXA is the wrapped JCA JMS connection factory. Other like java:/ConnectionFactory are standard JMS connection factories.
