Examples of javax.persistence.EntityManagerFactory.createEntityManager()

javax.persistence.EntityManagerFactory.createEntityManager()
Create a new application-managed EntityManager. This method returns a new EntityManager instance each time it is invoked. The isOpen method will return true on the returned instance. @return entity manager instance @throws IllegalStateException if the entity manager factoryhas been closed
