To expand on this, if you are joining on fields that will return only
one record for each value, you should still be able to make a primary
key for the returned records using a combination of the primary keys
of both records being joined. If hibernate only works with primary keys
consisting of one column, than you can create a new field using a function
of the primary keys of the records being joined.
