What is the difference between jboss.jms and jboss.mq ?

Question

What is the difference between the classes org.jboss.jms.server.destination.QueueService and org.jboss.mq.server.jmx.Queue?

Answer 1

org.jboss.jms.server.destination.QueueService is part of JBossMessaging, which is JBoss's new JMS implementation, supplied as part of JBoss AppServer version 5 and later (or JBoss EAP 4.3 or later)

org.jboss.mq.server.jmx.Queue is part of JBossMQ, which is part of JBoss's old (and now obsolete) JMS implementation, found in JBoss AppServer versions up to 4.2

Answer 2

JBoss Messaging will be replaced by JBoss HornetQ:

HornetQ takes over from JBoss Messaging as our premier JMS implementation.
