Hi, In fact, the annotation @ManyToMany does not function for my case, because my table WASNMI is not simply a table of joint, but it contains of another fields that the foreign keys.

It is HIBERNATE which is given the responsability to manage the keys themselves! Us, only the objects are managed.

You keep looking for an answer, but you don't seem to be paying attention to the answers you are getting. You certainly didn't seem to even look past the basic chapter on OR mapping in our JPA book. Take a look in Chapter 8. There is a "Mapping Relationship State" section there that discusses your exact association table situation.
