}

Ce qu'il se passe, c'est que j'avais une première version de ses deux entités qui étaient totalement indépendantes et les choses semblaient bien marcher.

A présent, la classe entité à un élément utilisateur et la classe utilisateur à une liste d'activité.
J'ai donc voulu rajouter les annotations de cardinalité pour la persistance en conséquence (ManyToOne, OneToMany)...mais malheureusement c'est là que tout a commencer à planter...et je ne m'y retrouve absolument pas...

Merci pour votre aide !
