[Hibernate] Composite key one-to-many XML Error

I have two tables (Customer and Address). A customer can have multiple addresses.
Both tables use composite keys.

I am getting this error... But I don't know how to fix it.

Here is the Customer.hbm.xml file...

Here is the Address.hbm.xml file...

Any suggestions are greatly appreciated. This is my first attempt at using any O/R mapping API and unfortunately I have to try it on composite key tables since that is all we have.

Your set elemnt doen't match the DTD for hbm files. The parse error:

is the DTD for the set element. If you are not used to dealing with XML definitions like this, you might want to look at DTDs on W3. What this line is telling you is a "set" element can only have one child "key" element. So you can't do this:

If you have a composite foreign key I'd get middlegen to generate the mapping for you, since writing composite foreign keys can be error prone.
