In my previous two posts on ActiveMQ and Spring I’ve shown how to implement both asynchronous and synchronous messaging using MessageListenerContainers and JmsTemplates. Since then I have continued to tweak and improve my use of Spring’s JMS support and have uncovered a few more details about the ConnectionFactories supplied by both ActiveMQ and Spring and how they play together nicely and not so nicely. Some of this info is new while some was covered in my second post and lead to an edit in my initial post but I will reiterate that information here to keep it all in one place.
