In EclipseLink 2.5.2, how can I obtain the instance of the org.eclipse.persistence.sessions.Project class that is associated with my existing PersistenceUnit / EntityManagerFactory so that I can call setDefaultQueryResultsCachePolicy?

Thanks.

EntityManager is an instance of org.eclipse.persistence.internal.jpa.EntityManagerImpl which contains databaseSession filed pointing to ServerSession instance. ServerSession has project attribute pointing to Project instance.
Try ((EntityManagerImpl)em).getServerSession().getProject() and you will get org.eclipse.persistence.sessions.Project instance.
