Spring ,hibernate et flex
salut tout le monde ,
je travaille sur un projet qui utilise les technologies hibernate, Spring et Flex , et la technologie flex intervient dans la couche présentation et ceci grâce au blazeds. J`ai fait un simple exemple qui implement la méthode hello , et ceci ca fonctionne, mais des que j`utilise hibernate j`arrive pas a extraire les données depuis flex et une erreur s`affiche lors de test
