Here's my database setup:

(this is a simple EAV stucture)
-----------------------------
user_id (FK) ----| Composite key
setup_item -----|
setup_value

So, the user_id and setup_item makeup the composite key of the table, on the java side, the only thing to note is that setup_item and setup_value come from a hashmap:

Code:

// Where String is "setup_item" and Object is "setup_value"
Map<String, Object> data = new HashMap<String, Object>()

I'm trying to map this relationship in a setup.hbm.xml file, but I can't figure out how to properly fit setup_item and setup_value into the composite-id. Is there some issue with how I have this setup?
