Bonjour,
Je viens de commencer un projet, j'ai créer un bean pour une interface d'inscription dans laquelle je doit récupérer des informations à partir de la base en utilisant les JpaController déja fournis, mais les problème s'avère lors de l'initialisation, en particulier avec EntityManagerFactory sachant que l'unité de persistance est configurée. Voici le code du bean:
