Hibernate criteria for a junction table - how to create?

I have simply 3 tables like:

product

.----------

id

name

category

.----------

id

name

product_category

.----------------------

p_id

c_id

I want to get a list of products where the products have category of id=3. I am confused about how to write a hibernate cr开发者_JAVA技巧iteria for this. Any help would be appreciated.

Thanks

Criteria c = session.createCriteria(Product.class, "product");
c.createAlias("product.categories", "category");
c.add(Restrictions.eq("category.id", 3));
