}La requête que je suis en train de l'exécuter:
Query q = session.createQuery("SELECT p FROM " + Presentation.class.getName() + " p");
presentationModel = new PresentationTableModel((List<Object[]>)q.list());Et ce est la façon dont je reçois la session pour exécuter des requêtes

- Collez l'exacte et complète trace de la pile de l'exception. Notons qu'une telle requête renvoie un
List<Presentation>, pas unList<Object[]>. - J'ai ajouté la trace de la pile, je l'ai changé pour une Liste<Présentation> mais le résultat reste le même

Comme documenté par exemple ici, le nom de l'entité par défaut le simple nom de la classe. Il ne contient pas le nom du package. Dans ce cas, le nom de l'entité est
Presentation.Méthode getName dans java.lang.Class déclarations de paquet, de sorte qu'il n'est pas utile dans ce cas. Mieux ḿethod pour ce cas est getSimpleName():
Comme une note de côté, probablement, il n'y a pas de raison d'utiliser org.mise en veille prolongée.les annotations.Entité au lieu de javax.la persistance.Entité.
@Entity(name="full.package.name.with.class.name")afin d'être en mesure d'utiliserclass.getName()?
