Conexión a PostgreSQL de la aplicación OSGI desplegada en el contenedor de KaraF

Question

Estoy usando Hibernate para conectarme a PostgreSQL desde un contenedor Karaf 2.3.4, cuando implemento mi paquete hay una excepción que dice javax.naming.amenotfoundException OSGI: Service / Javax.SQL.DataSource / "(Osgi.jndi .Service.name= JDBC / Postgresds).

Aquí está mi archivo Persistance.xml

Resolví este problema y actualicé la lista de archivos como dijo M. Cristian, pero el es un otro problema extraño: cuando se reinicia Karaaf y intentando insertar datos a través de la consola de KaraF, la letra de la consola: la no es una transacción activa, por lo que Probé la otra forma utilizando EntityManager y el problema ya no aparece.

Answer 1

Su código no puede funcionar, ya que la fuente de datos se publica en el mismo contexto de planos donde se usa una unidad de persistencia.

El problema es que el plan esperará un servicio enitityManagerFactory para inyectar.Así que la fuente de datos nunca será publicada.Aries JPA detectará que debería crear una EntityManagerFactory para su paquete, pero el tiempo de espera intentará encontrar el DataSource.

Así que ponga la fuente de datos en un haz de Spearate y debería funcionar.
