Great tutorial. My questions is, can you and if so how do you set up a relationship that uses a composite primary key. I know it is not the best way to design, but that is not the question. Can you do something like this? <set name="orderItems" table="order_items" cascade="all" inverse="true"> <!-- <key column="order_id"/> --> <composite-id> <key-property name="orderId"/> <key-property name="productId"/> </composite-id> <one-to-many class="test.hibernate.OrderItem"/> </set>
