You don't have to know EJBs before using JMS. I mean JMS came out first and now, starting with EJB 2.0 the Message Driven Beans are using JMS. If the question would have been "Do I have to know EJBs before using Message Driven Beans?" then the answer would be you should know the priciples behind EJB technology in order to use any kind of EJBs, but as the MDBs are not dirrectly related to Session Beans or Entity Beans knowing all of them is not mandatory. You can start out by learning dirrectly Message Driven Beans.

If you have to do transaction on both dbms and jms queue, then you might have to know a little bit on EJB. They are not hard at all, just keep it light, don't use container managed persistence and keep up to speed on how to use JTA.

Melody,
As Ernest already pointed out here, your display name doesn't comply with our naming policy and you will have to change it.
Thanks.
