Connessione a PostgreSQL dall'applicazione OSGI distribuita nel contenitore KARAF

Question

Sto usando ibernazione per connettersi a PostgreSQL da un contenitore Karaf 2.3.4, quando implementato il mio pacchetto c'è un'eccezione che dice javax.naming.namenotfoundException OSGI: servizio / javax.sql.dasasource / "(osgi.jnd .service.name= jdbc / postgresds).

Ecco il mio file persistiance.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
    <persistence-unit name="HibernateOSGi_ContainerManaged"
        transaction-type="JTA">
        <jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/postgresds)</jta-data-source>

            <property name="hibernate.format_sql" value="true" />
        </properties>
    </persistence-unit>
</persistence>

Ecco il mio file BluePrint.xml:

  <?xml version="1.0" encoding="UTF-8"?>

    </bean>

    <service ref="dpService" interface="org.hibernate.osgitest.DataPointService" />

Ed ecco il mio file DataSource-Postgres.xml

<?xml version="1.0" encoding="UTF-8"?>

Ho risolto questo problema e ho aggiornato l'elenco dei file come detto M. Cristian, ma è un altro strano problema: quando si riavvia KARAF e cercando di inserire dati tramite KARAF Console La console Stampa: non è una transazione attiva, quindi Ho provato l'altro modo di usare EntityManager e il problema non appare più.

Answer 1

Il tuo codice non può funzionare come DataSource è pubblicato nello stesso contesto di Blueprint in cui viene utilizzata un'unità di persistenza.

Il problema è che il progetto attenderà un servizio di enitityManagerFactory iniettare.Quindi il DataSource non sarà mai pubblicato.Ariete JPA rileverà che dovrebbe creare un'entityManagerFactory per il tuo pacchetto, ma il timeout sta cercando di trovare il DataSource.

Quindi metti il datasource in un pacchetto spearato e dovrebbe funzionare.
