[EJB2.1 Entity] Mon Bean entity n'ecrit pas dans la base ca reste temporaire (Persistance)

Bonjour,

Je travaille avec ejb2.1 xdoctlet, eclipse sous oc4j.

Mon problème est que mes beans CMP ne sont pas stocké dans la base de donnée ca reste disant temporaire.

Code:

1
2
3
4
Context ctx = new InitialContext(properties);
       Object objref = ctx.lookup ("My");
           home = (MyHome) PortableRemoteObject.narrow ( objref, MyHome.class ) ;
home.create(BigDecimal.valueOf(5), BigDecimal.valueOf(54));

Dans ce cas mon bean est créer je peut le manipuler mais pas enregistrer dans la base.

Si je cherche par clé primaire dans la base j'ai cette exception:

Code:

1
2
3
4
5

javax.ejb.ObjectNotFoundException: Exception [EJB - 10008] : bean de type [My] introuvable via la recherche [findByPrimaryKey].
