Most likely, you need a good book on EJB 3.0!
If you are using the Container Manager Persistence implemented in Enterprise Java Beans 3.0, you should check the documentation of the @SecondaryTable annotation.
You will also be interested in @SecondaryTables, @Table, and @Column.
Each secondary table will need to be able to be joined to the main table.

It is possible in EJB 2.1. EJB changed quite a bit between 2.0 and 2.1. I don't remember if it was possible in 2.0.
It tends to be app server specific though. For example, here's how to do it in WebLogic.
