I need some help with troubleshooting why my persistence unit is not loaded in Karaf using Hibernate. The log file reports
Bundle com.vogelware.simple.remote.combined is waiting for dependencies [(&(&(org.apache.aries.jpa.proxy.factory=true)(osgi.unit.name=person)(objectClass=javax.persistence.EntityManagerFactory))].
I think the issue is the EntityManagerFactory service is not running. Based on SO message Jpa-hibernate error while starting the service all of the required services are running. See below.
I have tried starting my persistence bundle before hibernate bundles but get the same behavior.
Listed below are the blueprints for datasource, persistence and persistence.xml.
Any suggestions on how to get this simple example running?
