I have table A with column CA, CB, CC to map to map collection for one-to-many association. CA and CB are primary keys. CA is foreign key. I want to map table A to class A with properties ca, cb and cc. Both CA and CB are String type.

what is the mapping definition? And what is the key of class A?

Hope someone could help me with this.
Thanks.

The key should be a component-id (manual chapter 5.1.5 ad 8.4) or composite-id.

(Tips: pointing out it is "urgent" is usually a good way NOT to get help on an e-mail list or forum... Urgent usually means "I have not tried myself yet, please do it for me")
