Hello there,

I am new to hibernate.

I have two table A & B.

Table A (C1_id, C2_id, A3);
Table B (C1_id, C2_id, C3_id, B4, B5);

With C1_id, C2_id, C3_id are primary columns.

I used composite-id for column C1_id & C2_id of table A.

What am I supposed to do for mapping table B to A?

Anyone please help.

Thank you very much.

It really depends on what you mean by "mapping".
I would recommend you specifying class (class="xxx") for composite id.

Class B can reference class A using multiple column elements in many-to-one or collection key...

See section 9.4 in Hibernate reference.
