Aries JPA Issue

[Ioannis Canellos]

Hi,

I am trying to build an application that uses aries jpa and deploy it to
karaf.
My application is similar to the blog sample application provided by aries.
Inside my application I have a bundle that contains the persistence unit, my
entities and a DAO (as an OSGi service via bleuprint xml).

This bundle falls in GracePeriod status, beacause it can't find  the
EntityManagerFactory(?):

Here is what I get in my log:

Found initial references null for OSGi service
(&(&(org.apache.aries.jpa.proxy.factory=*)(osgi.unit.name
=wicket-osgi-pu))(objectClass=javax.persistence.EntityManagerFactory))

18:36:45,823 | WARN  | l Console Thread | container                        |
er.impl.PersistenceBundleManager  564 | 171 - org.apache.aries.jpa.container
- 0.2.0.incubating | There are no providers available.

My persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="

  <persistence-unit name="wicket-osgi-pu" transaction-type="RESOURCE_LOCAL">
     <provider>org.datanucleus.jpa.PersistenceProviderImpl</provider>
    <non-jta-data-source>aries:services/javax.sql.DataSource/(
osgi.jndi.service.name=jdbc/blogdb)</non-jta-data-source>
    <class>net.iocanel.database.entities.Person</class>
  </persistence-unit>
</persistence>

My blueprint.xml

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

                <jpa:context property="entityManager"

        </bean>

        <service ref="personDAO"
                interface="net.iocanel.database.dao.PersonDAO">
        </service>

</blueprint>
