问如何调用命名查询

EN

List results = em.createNamedQuery("Voter.findvoter")
    .setParameter("voterID", "blah")
    .setParameter("password","blahblahblah")
    .getResultList();

@NamedQuery(name = "Voter.findvoter", query = "SELECT count(*) FROM Voter v WHERE v.voterID = :voterID AND where v.password = :password")
@Entity
public class Voter implements Serializable{ ... }

public class VoterFasade{
    public List<Voter> findVoter(long id,String password){
        List<Voter> results = em.createNamedQuery("Voter.findvoter")
            .setParameter("voterID", id)
            .setParameter("password",password)
            .getResultList();
        return result;
    }
}

@Inject
VoterFasade voterFasade;

///
long id=12;
voterFasade.findVoter(id);
