EJB project class extend hibernate project class

**mstrcos** · 12/02/2009, 11h41

Bonjour,

j'ai un projet EJB séparé en 3 parties :

Client : possédant mes Entités, mes services et mes interfaces Manager
EJB : possédant mes managersBeans, DAO et DAOImpl
Web : couche web

J'ai également un project hibernate divisé de la même façon.

appellons les PrjA (EJB) et PrjB (Hibernate).

Mon problème :

J'aimerais que mes classes entité de PrjA étendent d'une classe de PrjB.
exemple du début d'une de mes entités :

Code :

@javax.persistence.Entity	 
@javax.persistence.EntityListeners({AuditLogger.class})
@javax.persistence.Table(name = "MonSchema_CHANGE_TYPE", schema = "MonSchema")
@javax.persistence.SequenceGenerator(name = "sequenceCT", sequenceName = "MonSchema.MonSchema_SQ_CHANGE_TYPE", initialValue = 1, allocationSize = 1)
@javax.persistence.NamedQuery(name = "ChangeType.findAll", query = "select changeType from ChangeType AS changeType")    
public class ChangeType extends IdDto
    implements java.io.Serializable
{

la classe IdDto provient de mon projet hibernate.

J'ai mappé mes tables (pour plus de clarté, je n'en ai mise qu'une) de cette façon dans mon fichier persistence.xml :

PrjA :

Si je crée la classe IdDto dans prjA (EJB) et que j'étends mes classes ce celle-ci, cela marche évidemment. Si j'étends mes classes PrjA de IdDto de prjB et que j'éxécute un simple test : getAllChangeTypes(), au debug, j'arrive à la ligne où je récupère le résultat de ma query - qry.getResultList - ici (DAOImpl):

Code :

	public List<ChangeType> getAll() {
		Query qry = em.createNamedQuery("ChangeType.findAll");
		List<ChangeType> results = qry.getResultList();		
		return results;
	}

j'ai cette erreur :

Il fallait ajouter :

name="persistence/NOM_DE_MA_PERSISTENCE"

à

@PersistenceContext(unitName="prjA", name="persistence/prjA")
private EntityManager em;

dans mon fichier d'implémentation de DAO (ChangeTypeDaoImpl)

ouf !
