Unable to access persistent classes via OSGI Service

Solution Verified - Updated -

Environment

  • Red Hat JBoss Fuse 6.1.0

Issue

  • we are using OpenJPA with Fuse
  • when creating the named query with the EntityManagerFactory we are getting the below shown exception:
<openjpa-2.3.0-r422266:1540826 fatal user error> org.apache.openjpa.persistence.ArgumentException: There is no query with the name "ClaimCarrierSequence.findByCareerId" defined for any of the known persistent classes: [foo.model.ClaimCarrierSequence, foo.model.ClaimEventStatus, foo.model.ClaimEventProcessRequest, foo.model.ClaimEventProcessResponse, foo.model.ClaimEvent, foo.model.ClaimEventType].

Resolution

The easiest way to solve this kind of issue with the OpenJPA is to add the package of Entity class using DynamicImport-Package in Manifest file for the bundle which is exposing the OSGI service.
