Connexion à PostgreSQL à partir de l'application OSGI déployée dans le conteneur KARAF

Question

J'utilise Hibernate pour vous connecter à PostgreSQL à partir d'un conteneur KARAF 2.3.4, lorsque je déploierai mon paquet, il y a une exception annonant Javax.naming.Namenotfoundexception OSGI: service / javax.sql.dataSource / "(osgi.jndi .Service.name= JDBC / Postgresds).

Voici mon fichier persistance.xml

J'ai résolu ce problème et j'ai mis à jour la liste des fichiers comme dit M. Cristian, mais c'est un autre problème étrange: lors du redémarrage de Karaf et d'essayer d'insérer des données via Karaf Console à la console Imprimer: La console n'est pas une transaction active. J'ai essayé l'inverse de l'autre moyen d'utiliser EntityManager et le problème n'apparaît plus.

Était-ce utile?

La solution

Votre code ne peut pas fonctionner car la DataSource est publiée dans le même contexte de PlanPrint où une unité de persistance est utilisée.

Le problème est que le plan directeur attendra l'injection d'un service d'énittityManagerFactory.Donc, la DataSource ne sera jamais publiée.Aries JPA détectera qu'il devrait créer une entitéManagerFactory pour votre paquet, mais le délai d'attente d'essayer de trouver la source de données.

Alors, mettez la source de données dans un paquet spearate et cela devrait fonctionner.
