JMS%20Interview%20Questions%20and%20Answers

Question: What are the basic advantages of JMS?

Answer: JMS is asynchronous in nature. Thus not all the pieces need to be up all the time for the application to function as a whole. Even if the receiver is down the MOM will store the messages on it's behalf and will send them once it comes back up. Thus at least a part of application can still function as there is no blocking.
