EJB3 eclipseLink et JBOSS EAP6 avec POSTGRES insert non effectuée
Bonjour
J'ai récupéré un projet que je migre de MYSQL vers POSTGRES et sous JBOSS EAP6 6.4.22
Lorsque dans ma form je cherche à inserer un nouvel enregistrement
* je n'ai aucun message d'erreur
* et l'insert n'est pas effectué dans POSTGRES
* mais la sequence qui sert de clef primaire est bien incrementée !!
j'utilise org.eclipse.persistence.jpa.PersistenceProvider et POSTGRES12
Où est mon erreur ? Merci d'avance

Je pense que mon soucis provient de la gestion ou non gestion des transactions par mon JBOSS EAP6
