Composite Key mapping issue

Hello all, I've been struggling for a while now with how to setup a relationship. I have two objects, one being a Listing object, the other a Tax object. The relationship is a one-to-one (not constrained). The primary keys for each are as follows:

Code:

Listing = mlsID (String) + associationID (long)
Taxes = associationID (long) + taxID (string)

I have the

Code:

taxID

also in the Listing object. I've looked through all the documentation for Hibernate 1.2 and can't seem to find anyway to let hibernate handle the relationship of these two objects for me. Mostly I am interested in cascade deletes. Anyone have any thoughts as to how I should approach this? If I can't find a way then I will have to handle the relationship manually but would really like to avoid that.

Much much thanks in advance,
-Jay

just use key-many-to-one from Listing to Taxes or Taxes to Listing

it will do what you need

Is the key-many-to-one compatible with hibernate 1.2? I dont see it listed in the DTD

Thanks,

No it is not.

Figured... I have been avoiding the migration to 2.0 because it's going to cause some major headaches. Guess I have no choice now.

Thanks again,
