Java EE:links to learn JBoss/EJB and JMS

I'm a core Java developer and now interested to learn EJB and JMS.

Could anyone give me links to learn those from 开发者_JAVA百科scratch? I mean I need a basic introduction to start with Java EE technologies. I also need to use the JBoss server and a Swing client for development. Please point me to useful links related to this too.
