我有一个关于namedQuery的问题，问题是在我的一个JTextfields的一个focuslost我有一个搜索代码如下：
private List<Condutor> condutor;
private void condutorIdFieldFocusLost(java.awt.event.FocusEvent evt) {
Query condByCod = entityManager.createNamedQuery("Condutor.findByCondutorId");
condByCod.setParameter("condutorId", Integer.parseInt(condutorIdField.getText()));
condutor = condByCod.getResultList();
infracaoNomeMotField.setText((String) condutor.get(1).getCondutorNome());
}
我的班级：
@Entity
@Table(name = "condutor", catalog = "infracoes", schema = "")
@NamedQueries({
@NamedQuery(name = "Condutor.findAll", query = "SELECT c FROM Condutor c"),
@NamedQuery(name = "Condutor.findByCondutorId",
query = "SELECT c FROM Condutor c WHERE c.condutorId = :condutorId"),
例外，我已更新到完整的消息：
