Le mappage étant généré cette fois ci par le biais de Hibernate Tools.
J'ai l'impression qu'il me crie dessus pour me dire que l'id de TbRole est mauvais cependant il est en auto-generate...

non il te dit que tu as un objet A qui référence un objet B, que tu essaie de sauver A, mais comme B n'est pas encore sauvé sur la DB, c'est impossible. Commence par sauver B avant de sauver A ou ajouter un cascade persist sur la relation.

@ManyToMany(cascade = CascadeType.ALL)
J'ai bien essayé avec l'annotation suivante sur la classe TbUser le résultat reste le même.

Merci pour votre réponse rapide en tous cas !

J'ai également effectué des tests avec les deux annotations suivantes. Celle en commentaire représentant l'annotation généré par Hibernate tools.

salut,
peux-tu nous montrer le code avec lequel tu fais ta sauvegarde?

Salut,

Ma classe manager est en commun avec le second tropic ouvert sur un sujet quasi similaire.

http://www.developpez.net/forums/d15...y-persistance/

Pour la classe main je la posterais ce soir mais rien de très extravagant

- appel du constructeur dao
- initialisation de user qui fonctionne sans l'ajout de role.

Appel de dao.Create avec user en paramètre

salut,
essaies ceci:

Code:

1
2
@ManyToMany(mappedBy = "tbRoles" , cascade = {CascadeType.ALL}) 
private Set<TbUser> tbUsers;

et

Code:

1
2
3
4
5
@ManyToMany(cascade = {CascadeType.ALL})
@JoinTable(name = "tb_user_role", catalog = "brest2016", joinColumns = {
			@JoinColumn(name = "tb_user_D_US_CODE", nullable = false, updatable = false) }, inverseJoinColumns = {
					@JoinColumn(name = "tb_role_D_RO_CODE", nullable = false, updatable = false) })
private Set<TbRole> tbRoles =  new HashSet<TbRole>();

dans leur classe respective.

Eric

Merci de ta proposition j'essaie la solution dès ce soir ! Le problème viendrait de l'initialisation de la liste de rôles ? Même modification à faire cote TbRole ? Pour la liste de users ?

Suite à la modification le résultat reste le même.
