Problema de Coersao

Programação Java
#1

Boa Noite,

estou em desenvolvimento web, tenho minha classe CRUD de persistencia e faz a chamada de StoredProcedure validarlogin com parametros de email e senha e me retorna int, estou com problemas de coersao java.lang.ClassCastException: java.lang.Integer cannot be cast to br.data.model.Usuario

como posso solucionar, abaixo codigo Metodo do Crud

public Object loggin(String email, String senha) {

    EntityManager em = emf.createEntityManager();
    try {
        em.getTransaction().begin();
        
        
        
         return em.createNativeQuery("select validarLogin('" + email + "','" + senha + "')").getFirstResult();

      
        //return em.createNamedQuery("Usuario.findByEmailSenha").
        //setParameter("email", email).setParameter("senha", senha).getSingleResult();

        /*
         * @NamedQuery(name = "Usuario.findByEmailSenha", query = "SELECT t
         * FROM Usuario u WHERE u.email = :email AND u.senha = :senha")})
         */
    } catch (Exception e) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", e);
        em.getTransaction().rollback();
        return null;
    } finally {
        em.close();
    }

}

Desde já Agradeço… :wink:

Veja a linha onde ocorre esta ClassCastException e nos informe. Aparentemente eu não detectei o problema. Talvez esteja numa outra parte do sistema, e não aí.

Dica: Use as tags code pra colar seu código no fórum.
