Web Service SOAP NullPointer erreur
Bonjour à tous.
Je débute dans le développement de web service et je n’arrive pas à ajouter, modifier et supprimer des entités depuis mon client vers ma db en passant un service SOAP.
J’ai créé un projet Entreprise Applicaion avec un Module EJB et une Application Web avec Glassfish 4 pour serveur.
Dans mon module EJB j’ai importé mes entités depuis ma db et créé un session bean pour requêter dans ma db.
Dans mon application web, j’ai ajouté un service web en indiquant mon bean de mon module ejb ce qui m’a générer automatiquement les méthodes.
Dans un client java, j’ajoute un web service client en lui indiquant l’url wsdl de mon web service. Lorsque j’appelle les méthodes GET, il n’y a aucun problèmes, je récupère bien les données de ma db. Par contre lorsque je veux modifier, ajouter ou supprimer une entité, j’obtiens une erreur NullPointer de mon objet passé en paramètre.
