i was impressed on how jboss did this i declared a many-many relationship in the ejb-jar.xml and jboss created the link table on its own with the necessary stuff needed

Hello,

By default, JBoss can take decision by itself if you don't specify anything. Consequently, most CMP2 applications do not require a jboss specific deployment descriptor at all (at least during prototyping, when you don't care about table names, etc.)

Okay, so I finally found out that jboss will generate the linking table on it's own for a many to many relationship. But is it possible to map a pre-existing linking table for the link between two tables in a many to many relationship? I can't find any examples of how to do this in the orielly book, or in the jboss-specific workbook. I just want to use a pre-existing link table that I already have.

Yes, this is described in the JBossCMP specific book in details.

Cheers,

I believe the J2EE Patterns book available at www.theserverside.com provides a good clear explination of different approaches to achieving CMR with or without control control by the container.

Its a good book, although lacks XDoclet.
