Je suis débutante en développement web à base de java EE, je construits la portail intranet en utilisant les technologies JSF2, JPA2, EJB3, glassfish, Eclipse Kepler, Maven2, PostGrSQL 9.1, et eclipseLink comme provider de la couche JPA2, en fait j'essaye d'afficher la liste des formations de la base de donnée sur le navigateur et les propriétés de chaque formation, mais on m'affiche l'@ phisique de la ligne au lieu de sa valeur:
Pièce jointe 141361
