Should be:

Code:

<class name="OrderDetails, xxx" table="orderDetails">
<composite-id>
   <key-many-to-one name="Product" class="Product, xxx" column="ProductsID" />
   <key-many-to-one name="Order" class="Order, xxx" column="OrderId" />
</composite-id>
<property name="Quantity" column="Quantity" type="Int32" />
</class>
