Cliente cli= (Cliente)entityManager.createNamedQuery("findCliente").setParameter("nCli", noCli).getSingleResult();
System.out.println("Cliente name: " + cli.getNombre());
return cli;
}
}
when i do debugging, i have a one error, when i use entityManager in this line
| Cliente cli= (Cliente)entityManager.createNamedQuery("findCliente").setParameter("nCli", noCli).getSingleResult(); |
it´s the error
