Hi all, I have a problem with the @ManyToMany annotation on a Set container (OpenJPA 2.1.0) : When I generate my database (Derby 10.7) the generated join table have two foreign keys but no primary key !
My question is : How can I add a primary key (or unique) constraint on the join table with OpenJPA to prevent duplicate row inside DB table ?
