yes CMR does work in 3.0.4
thank u for ur mail. could u pls tell me whether we need to write cmr related information in any of the xml files of the JBoss. why because its taking my relation as a column which wouldn't be there in the database table..
you need to add the standard element in ejb-jar.xml. This is enough with default mappings. Additional configuration can be made in jbosscmp-jdbc.xml but is not mandatory.
