The problem is that you probably have the persistence.xml and the entity
classes in the same bundle.
See:
https://issues.apache.org/jira/browse/ARIES-1433
Aries JPA container watches for bundles with the Meta-Persistence
header. If the bundle enters Starting or Active state then Aries JPA
creates the EntityManagerFactory and adds it as a service in the name of
the bundle.
The problem is now that if you also have the bean that uses the
EntityManagerFactory in the same bundle then blueprint will never start
up. Apparently this denies the bundle to enter the Starting or Active
state.
So Aries JPA will never publish the EntityManagerFactory.
I am not sure if we can fix this. So the best practice is to always
separate the persistence unit bundle from bundles using the EnityManager.

Hello.
I have a problem with a simple service. This service is created using
blueprint with the following file:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:jpa="http://aries.apache.org/xmlns/jpan/v1.0.0";
xmlns:tx="http://aries.apache.org/xmlns/transactions/v1.2.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
>
<jpa:enable/>
<service ref="ornitodataservice2"
interface="org.llaroqui.ornitorrinco.data.service.api.IDataService" />
<bean id="ornitodataservice2"
class="org.llaroqui.ornitorrinco.data.service.impl.DataService">
<property name="theDao" ref="dao"/>
<tx:transaction method="*" value="Required" />
</bean>
<bean id="dao"
class="org.llaroqui.ornitorrinco.data.service.impl.Dao">
</bean>
</blueprint>
The problem is that if I include it in the jar (in the OSGI-INF / blueprint
folder) the service does not appear in the list of services but if I do
leave the file in deploy folder, the service appears.
If I do both, the log tells me:
Bundle service-impl/0.0.1 is waiting for dependencies
[(&(osgi.unit.name=ornitoJPA)(objectClass=javax.persistence.EntityManager))]
(I change the service id).
