Chama o commit e depois fecha a conexão.

Nesse post aqui tem um exemplo: Hibernate 3 com JPA 2

nao deveria funcionar? pois EU ACHO (NÉ) que eu criei outra conexao.. segue a classe que cria novas conexao:

package br.com.hibernate;

import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class ManagerHibernate implements Controller {
	
	private EntityManager manager;
	
	public ManagerHibernate() {
		EntityManagerFactory fac = Persistence.createEntityManagerFactory("livraria");
		this.manager = fac.createEntityManager();
	}
	
	public EntityManager getManager(){
		return this.manager;
	}

	@Override
	public void insert(Controller ct) {
			
			EntityManager manager = new ManagerHibernate().getManager();
			manager.getTransaction().begin();
			
			try {
				manager.persist(ct);
				manager.getTransaction().commit();
			} catch(Exception e){
				e.printStackTrace();
				manager.getTransaction().rollback();
				System.out.println("ERRO: ".concat(e.getMessage()));
			} finally {
				manager.close();
			}
		}

	@Override
	public List<Controller> findAll() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public Controller findEspecific(int id) {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public void remove(Controller ct) {
		// TODO Auto-generated method stub
		
	}
}
