If you forget to add the destination property to the activationConfig for an MDB, when deploying to JBoss AS7 you’ll get this NullPointerException. Would be better if it told you what required property was missing:

Here’s a correctly configured MDB:
@MessageDriven(mappedName = "queue/QueueName", activationConfig = {
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/queueName") })
public class QueueListener implements MessageListener {
...
}
