javax.persistence.PersistenceException: Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.4.0.v20120229-r10915): org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: Predeployment of PersistenceUnit [herakles] failed.
Internal Exception: Exception [EclipseLink-7161] (Eclipse Persistence Services - 2.4.0.v20120229-r10915): org.eclipse.persistence.exceptions.ValidationException
Exception Description: Entity class [class ch.eugster.herakles.persistence.model.TectonicsLevel] has no primary key specified. It should define either an @Id, @EmbeddedId or an @IdClass. If you have defined PK using any of these annotations then make sure that you do not have mixed access-type (both fields and properties annotated) in your entity class hierarchy.
