Bonjour,
J'ai implémenté un exemple de projet web dynamic pour tester JPA et Mysql mais rien ne marche à chaque exécution ce message d'erreur :

-> Si bien que j'ai installé les jars suivants sous eclipse :
eclipselink-jpa-modelgen.jar, mysql-connector-java-5.bin.jar et javax.persistence.jar.
*****Est-il important d'ajouter le fichier orm.xml quand on utilise déjà les annotations dans les classes entités???
