Olá, pessoal!
Estou tentando para retornar o valor mas apareceu erro de persistencia. veja em baixo.

Esse metodo fica dentro Managed Bean do Aluno para carregar um dado do aluno. mas eu usei o paramento para usar o filtro
public String getPagDadoAluno() {
alunoController = new AlunoJpaController(null, conn.getEntityManagerFactory());
aluno = alunoController.findAlunoUsuario(logado.getIdUsuario());
return pagDadoAluno;
}metodo fica no AlunoJpaController que gerencia todas as persistencia.
public Aluno findAlunoUsuario(Integer id) {
EntityManager em = getEntityManager();
Aluno aluno = null;
Query qAluno = em.createNamedQuery("Aluno.findByUsuario");
qAluno.setParameter(1, id);
try {
aluno = (Aluno) qAluno.getSingleResult();
} finally {
em.close();
}
return aluno;
}Na Classe Aluno que eu criei na query.
@NamedQueries({
@NamedQuery(name = "Aluno.findAll", query = "SELECT a FROM Aluno a"),
@NamedQuery(name = "Aluno.findByMatriculaAluno", query = "SELECT a FROM Aluno a WHERE a.matriculaAluno = :matriculaAluno"),
@NamedQuery(name = "Aluno.findByDtNascimento", query = "SELECT a FROM Aluno a WHERE a.dtNascimento = :dtNascimento"),
@NamedQuery(name = "Aluno.findByTelefone", query = "SELECT a FROM Aluno a WHERE a.telefone = :telefone"),
@NamedQuery(name = "Aluno.findByUsuario", query = "SELECT a FROM Aluno a WHERE a.usuario = :codUsuario")})Tentei várias vezes e não encontramos para resolver a problemas
