Bonsoir

be lève les // ... comme on dit par ici

Code:

---

1 2 3 4 5 6 7

public void run() { try { new AddDecisionsJFrame1().setVisible(true); // new Fenetre().setVisible(true); } catch (SQLException ex) { Logger.getLogger(AddDecisionsJFrame1.class.getName()).log(Level.SEVERE, null, ex); }

---

C'est pas prêt de compiler ton histoire, il faudrait déclarer tous les (50) composants utilisés

Code:

---

1 2 3 4 5 6 7

private void initComponents() { jLabel1 = new JLabel(); CmdSave = new JButton(); jLabel2 = new JLabel(); TxtDecId = new JTextField(); jLabel3 = new JLabel(); jLabel4 = new JLabel();

---

Tu testes pas ton code au fur et à mesure que t'écris?

Ha oui compris
