> After migrating an OC4J/TopLink Essentials project to JBoss/Hibernate, there were some breakdowns. I have some entities with composite keys (specifically - 4 ID fields). There is a separate ID Key class. These field names do not match the database fields directly but are mapped with @Column(name="A_B_C"  nullable="false") style notation with the field names as aBC. The SQL generated thus looks for 'TABLEONE0_'.'aBC' specifically on the ID fields of the entity instead of 'TABLEONE0_'.'A_B_C' they should be mapping to. The rest of the attributes map out alright. 
> By the way I just wanted to note that all the code that is breaking down was working fine on OC4J with toplink - FYI.
