one to one relation between PKs
Hi all,
I have a small problem with relation between Primary Keys in EJB's but I don't know if I do some errors or if there are some restrictions in JBoss.
I have two EJB's entity "A" and "B".
A has one pk called "aId" and some other fields.
B has two pks, bId1 and bId2 and other fields.
I have to place on B two one-to-one relation to A: the first between the pk-field of B: bId1 and the pk-field of A: aId and the second between B: bId2 and A: aId.
I produced the necessary files (java + xml + jar) but when I deploy the jar in JBoss I obtained the following Exception:
15:00:13,679 ERROR [EntityContainer] Starting failed
org.jboss.deployment.DeploymentException: Mappings were not provided for all fie
lds: unmaped fields=[bId2] in role=bRelationshipRole

I'm using JBoss-3.2.2RC1_tomcat-4.1.24 and MySQL for deploying and JBuilder or Eclipse+Lomboz like IDE.
Thanks.
