[jboss-user] [EJB 3.0] - Re: Need some help with mapping

[fhh]

Your ERM is broken :-)

If the primary key in the type table has three columns, then any foreign key referencing the type table must also have three columns. This is not a requirement of java persistence or hibernate but of any underlying sql database.

Ask whoever created this mess to create a foreign key constraint between the two tables. That is the easiest way to convince them they made a mistake.
