Examples of javax.persistence.EntityManager.persist()

javax.persistence.EntityManager.persist()
Make an entity instance managed and persistent. @param entity @throws EntityExistsException if the entity already exists.(The EntityExistsException may be thrown when the persist operation is invoked, or the EntityExistsException or another PersistenceException may be thrown at commit time.) @throws IllegalStateException if this EntityManager has been closed. @throws IllegalArgumentException if not an entity @throws TransactionRequiredException if invoked on acontainer-managed entity manager of type PersistenceContextType.TRANSACTION and there is no transaction.
