composite primary key example:

Code:
<composite-id>
          <key-property column="id" name="id" type="int"/>
          <key-property column="year" name="year" type="long" length="4"/>
</composite-id>

How do i create a composite unique key ?

By default hibernate creates a primary key id. But I want another two columns which should be always unique when considered together..
