merci d'avance

**tchize_** · 30/03/2016, 19h58

Tu as défini deux entités JPA appelées "Civilite" fr.ietevents.serviceweb.Entity.Civilite and fr.ietevents.client.Entity.Civilite. C'est tout simplement interdit, les noms doivent être uniques. La question est d'ailleurs de se poser pourquoi tu as deux sets d'entités, ça n'a pas de sens.

**mimi6060** · 30/03/2016, 20h06

fr.ietevents.serviceweb.Entity.Civilite et fr.ietevents.client.Entity.Civilite sont 2 projets java différents.
Pourquoi il viendrait à faire le lien entre 2 war différents qui sont connecté à 2 base de donnée différente ?
Pourquoi on pourrais pas avoir une entité civilité dans un projet de gestion de personnel ,
et dans un autre projet avoir une entité civilité pour un projet de vendeur de voiture et que ça n'aurais pas de sens ?

**tchize_** · 30/03/2016, 20h18

Ben entre des war différents ça ne pose pas de problème, les wars sont isolé. Si tu as ce message, c'est parce que les deux entités sont dans le même war, pointant vers la même base de donnée via l'entity manager. Tu as du commettre une erreur en construisant ton war et inclure par erreur les classes de ton webservice.

**mimi6060** · 30/03/2016, 20h30

Il s'agit de 2 war différent .
je peu voir ou les fichier inclure par erreur les classes de mon webservice?
Car dans le fichier persistance je ne vois pas de référence a Webservice dans client.

JPA scanne automatiquement à la recherche de tout ce qui a une annotation @Entity.

Pour voir ce qu'il y a dans le war, il suffit d'aller dedans. Les classes sont soit dans le WEB-INF/classes soit dans le wEB-INF/lib

tu construit comment ton war?
