Hi all, First of all, I don't kow if I am posting this question in the right forum, since the "old" hibernate forums (forum.hibernate.org) now redirect to the JBoss page and could find no trace of them. I have two tables in my database schema clients: clientid*, name products: productid*, name I want Hibernate to map it these to 3 POJOs: class Client { int id, Name name} class Product {int id, Name name} class Name { String name } Mapping the first two is simple, but is there a way to tell Hibernate that Name instances correspond to a join of the names from the two tables? What I would like is to be able to query all the Name instances in the database (and if removed one name, remove its entrances in both tables) without an explicit query.
