J'ai quelques requêtes longues (texte sage) que je suis en train d'extérioriser dans un fichier orm.xml pour des raisons de lisibilité et de maintenabilité, mais je continue à avoir un exception de la cartographie. Impossible de lire XML Voilà ce que j'ai:

Voilà comment je Injecter la EntityManager dans mon DAO
@Repository
public class K12DaoImpl implements K12DaoManager{
@PersistenceContext
private EntityManager em;
@Override
@Transactional(readOnly = true)
public List<AttendanceBreakDown> getAttendanceBreakDownBySchoolAndGP(int school, String gradingPeriod, String gradeLevel) {
Object values[] = new Object[]{new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradeLevel
};
Query query = em.createNamedQuery("attendanceDetailsBySchoolAndGradingPeriod");
for (int i = 0; i < values.length; i++) {
query.setParameter(i, values[i]);
}
List<AttendanceBreakDown> list = query.getResultList();
return list;
}
}
Quand je fais un mvn tomcat propre: run Je reçois un InvalidMappingException: Impossible de lire XML Il semble que ce ne est pas trouver le orm.xml partout que je ne vois pas où l'erreur de cartographie est.
J'ai extériorisé des requêtes avec succès en utilisant Hibernate avant d'avoir des fichiers HBM que les requêtes de carte aux objets et avoir ces fichiers hbm référencés dans le hibernate.cfg.xml mais maintenant je veux utiliser JPA 2.0 directement en utilisant EntityManager.
