Error calling save method using JSF Hibernate JPA An established connection has been overridden by the software on the host computer

Question

I am trying to save the data from my form but when I click save of error saying that "An established connection was annulled by the software on the computer". But when I test the save method using Junit works norlmally . Someone might be helping me ?

These are my statements

That is the part of the entity

@Entity
@Table(name = "tb_login")
public class LoginEntity { // This the beginning of the class from the entity LoginEntity

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Long id;

@Column(name = "name", nullable = false)
private String name;

@Column(name = "cpf", nullable = false, unique = true)
private String cpf;

@Column(name = "login", nullable = false)
private String login;

@Column(name = "password", nullable = false)
private String password;

// This the end of the class from the entity LoginEntity

This is the DAO part

public class LoginDAO {

public void save(LoginEntity loginEntity) {

    try {
        EntityManager entityManager = HibernateUtil.getEntityManager();
        EntityTransaction entityTransaction = entityManager.getTransaction();

        entityTransaction.begin();
        entityManager.persist(loginEntity);
        entityTransaction.commit();

        entityManager.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}
}

This is Bean’s part

@ViewScoped
@ManagedBean(name = "MB_LoginBean")
public class LoginBean {

// here is the beginning of the atributes from the class LoginBean
private LoginEntity loginEntity = new LoginEntity();

private LoginDAO dao = new LoginDAO();

// here is the end of the attributes from the class LoginBean

public void save() {

    dao.save(loginEntity);

}

This is my test using Junit

@Test
public void salvar() {

    LoginDAO dao = new LoginDAO();
    LoginEntity loginEntity = new LoginEntity();

    loginEntity.setName("Teste salvar 5");
    loginEntity.setCpf("0175472");
    loginEntity.setPassword("145258");
    loginEntity.setLogin("admin5");

    dao.save(loginEntity);
}

}

I was able to resolve, I was using Sessionfactory for the database connection and using Entimanager commands, so I created my connection to the database using persistence.xml and used the Entitymanger commands and it worked all right
