Hi,

I've been looking for a clue to solve this for too long by now! I'm trying to do a simple example using relationships in Jboss 3.2(Customer, Address - many to many using a table with an attribute, actually implementing a CustomerAddress table) and at deployment time I get the following:


10:23:00,840 INFO [Server] Release ID: JBoss [WonderLand] 3.2.2 (build: CVSTag=
JBoss_3_2_2 date=200310182216)
...

10:49:54,340 ERROR [EntityContainer] Starting failed
org.jboss.deployment.DeploymentException: No ejb-relationship-role-name element
found
...

I have checked over and over the deployment descriptors for the problem but could not find the problem. Does any one have a clue?
