RE: [JBoss-user] CMP2.0 Foreign Key (?) Problem
If we weren't exchanging messages over email you'd see me doing a little victory dance right now! Which, not too surprisingly, makes me glad we're exchanging messages over email. I was using a version of JBoss pulled from CVS in the last day or two, but was using examples and docs that applied to the alpha release. Right before your email I had decided that JBoss was completely ignoring everything I had in my jbosscmp-jdbc.xml file - which it was, because I was using the old style where and wrapped the roles. Who would have thought to go look at the DTD? I mean, it's only the exact description of how I should be formatting the config file. Sigh... Thanks for kicking me in the right direction, everything works wonderfully now.

Re: [JBoss-user] CMP2.0 Foreign Key (?) Problem
This is definitely a job for the jbosscmp-jdbc.xml file. What version of JBoss are you using? The structure of this file changed between the alpha and the beta. The xml for the classic Order-LineItem in JBoss 3.0 beta follows: Order-LineItem order.getLineitems() ordernumber ORDER_NUMBER lineitem.getOrder() As you can see the roles have been moved out of the foreign-key-mapping element and keys are always specified in terms of the current entity which is backwards from the old foreign key mapping but exactly the same as the table-mapping.
