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"/> -->
<key-property name="orderId"/>
<key-property name="productId"/>
<one-to-many class="test.hibernate.OrderItem"/>
