Debug level Hibernate log excerpt:

Hi all, i got 5 tables: a product(primary key id), a versionProduct(value, product_id foreign key), a component(primary key id), and a versionComponent(value, component_id foreign key). The last one is the join table: products_has_components(product_id foreign key, productVersion_value, component_id foreign key, componentVersion_value).

In fact the primary key of product should be composed of both product_id and version_value and same for components cause i would like to have components with specific versions associate with specific versions of a product.
if someone know how to do that i'll be very pleased??
