    <p>I am trying to get an email adresss from a database to make it the "InternetAddress recipient" but it returns me a nullPointerException and no more informations about the problem. Here is the code :</p> <pre><code>public class SendEmail implements ISendMail { @Override public void sendEmail(Action action) { if (action.getCopieAction() != null) { try { Properties props = new Properties(); Session session = Session.getInstance(props); Message message = new MimeMessage(session); UtilisateurDao user = new UtilisateurDao(); // récupération du code user de l'utilisateur Integer codeUserEnCopie = action.getCopieAction(); System.out.println(codeUserEnCopie); Utilisateur util = user.findUserByCode(codeUserEnCopie); String mailUserCopie = util.getEMAIL(); InternetAddress recipient = new InternetAddress(mailUserCopie); message.setRecipient(Message.RecipientType.TO, recipient); message.setSubject("Vous êtes en copie d'une action"); message.setText("Bonjour, l'utilisateur " + action.getUtilCreation() + " vous à mis en copie d'une action:" + "Nom de l'action : " + action.getObjetAction() + "Détails de l'action : " + action.getTexteAction() + "Date de l'action : " + action.getDateAction()); Transport.send(message); } catch (NoSuchProviderException e) { System.err.println("Pas de transport disponible pour ce protocole"); System.err.println(e); } catch (AddressException e) { System.err.println("Adresse invalide"); System.err.println(e); } catch (MessagingException e) { System.err.println("Erreur dans le message"); System.err.println(e); } } } } </code></pre> <p>The function that get the user in database</p> <pre><code>public Utilisateur findUserByCode(Integer codeUser) { System.out.println(codeUser); Utilisateur util = new Utilisateur(); util = null; try{ System.out.println("ddd"); Query requete = em.createQuery("SELECT u FROM Utilisateur u WHERE u.codeUtilisateur="+codeUser); requete.setParameter("codeuser", codeUser); util = (Utilisateur) requete.getSingleResult(); }catch(NoResultException e){ System.out.println(e.getMessage() + e.getCause()); FacesMessage message = new FacesMessage(e.getMessage() + e.getCause()); FacesContext.getCurrentInstance().addMessage(null, message); e.printStackTrace(); } return util; } and the fonction that calls the fonction sendEmail public void creerAction(Action action) { try { ISendMail sendMail = new SendEmail(); sendMail.sendEmail(action); System.out.println(action.getCopieAction()); em.persist(action); em.flush(); FacesMessage message = new FacesMessage("Action " + action.getObjetAction() + " ajouté avec succès avec en copie"+ action.getCopieAction()); FacesContext.getCurrentInstance().addMessage(null, message); } catch (PersistenceException e) { System.out.println(e.getMessage()); } } </code></pre> <p>How can i do to have more information aboout the error?</p> <p>STACKTRACE:</p> <pre><code>javax.faces.el.EvaluationException:

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
