JBoss AS and ActiveMQ

I’ve created 22+ minutes screencast about JBoss AS and ActiveMQ integration

In this screencast you’ll learn how to:

1. Deploy ActiveMQ
2. Run consumer/supplier samples
3. Integrate JBoss AS 6 and ActiveMQ
4. Enqueue TextMessage from EJB using ActiveMQ

			producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

			String content = (new Date()).toString();
			TextMessage msg = session.createTextMessage(content);

			producer.send(msg);

		} finally {

		System.out.println("Task has been performed");
