Hi Nicolas,
maybe you can take a look on:
https://github.com/jbonofre/acna15/tree/master/persistence
It shows the use of persistence.xml in a bundle to create the entity manager and
expose a DAO as service.
Especially you have to define the persistence.xml in the MANIFEST using the
following configuration statement to the maven-bundle-plugin:
<Meta-Persistence>META-INF/persistence.xml</Meta-Persistence>

friends I'm new to Karaf, I'm trying to create entity manager factory using
the below code but unable to create it
Code:
new HibernateOgmPersistence().createEntityManagerFactory("MY_PU", props);
persistence.xml:
<persistence-unit name="MY_PU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
<class>internal_class</class>
<properties>
<property name="hibernate.ogm.datastore.provider"
value="org.hibernate.ogm.datastore.cassandra.impl.CassandraDatastoreProvider"
/>
<property name="hibernate.ogm.datastore.host"
value="localhost" />
<property name="hibernate.ogm.datastore.port" value="9142"
/>
<property name="hibernate.ogm.datastore.database"
value="ALPHA" />
<property name="hibernate.ogm.datastore.grid_dialect"
value="org.hibernate.ogm.datastore.cassandra.CassandraDialect" />
</properties>
</persistence-unit>
My persistence.xml file location is in
src/main/resources/META-INF/persistence.xml, However if I try using
Persistence.createEntityManagerFactory, I get
Exception in thread "main" javax.persistence.PersistenceException: No
Persistence provider for EntityManager named MY_PU. Please help how I can
overcome this issue
I tried below options:
1. Placed META-INF/persistence.xml under src/main/java.
2. Made configuration changes in eclipse to remove the resource folder's
excluded list from *.* to None.
3. Tried creating entity manager using new
PersistenceProvider().createEntityManagerFactory("MY_PU")
4. Tried with Eclipselink
But none of the above steps solved my issue. How can I make Karaf identify
the persistence.xml file location and make it read the persistence units. I
saw some post on making ConfigAdmin service configuration, can someone
thrown some light on ConfigAdmin service with sample code.
Thanks
