Re: [Hibernate-devel] generating schema with referential integrity

[Gavin_King/Cirrus%<CI...@ci...>]

You need to decide wether Product is a component, or an associated object.
If its a component, it lives in the same table as LineItem and doesn't need
its own seperate <class> mapping (the mapping is done in the <component>
element. If Product is an entity (which i think is what you want here),
then use:

  <many-to-one name="product" class="openbx.domain.Product"/>

in the mapping for LineItem. (ie. instead of <component
....>....</component>)

Hope thats clear enough....

PS. I recommend you download the latest version it has important bugfixes.
