Creer un jPanel

Bonjour,

J'utilise ce code ci dessous pour insérer un jpanel qui a une image de fond dans un jpanel existant.
Le jpanel ne s'affiche pas dans l'application, et j'ai mis un sysout dans la redefinission du paintComponent de la classe JImagePanel et il ne s'affiche jamais.
N'y aurait il pas un problème avec les layout ?
Ne faut il pas spécifier des layout dans le nouveau jPanel qu'il créer ?
Je vous joint ci dessous le descriptif des layout de mon panel existant.

Code:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        // TODO add your handling code here:
        String chemin = "/ressources/img/pingouins.jpg";
        URL url = this.getClass().getResource(chemin);
        System.out.println(url.toString());
        jLabel1.setText(url.toString());
 
        // On met l'image sur le jLabel
        jLabel2.setIcon(new javax.swing.ImageIcon(url));
 
        /** Accès au toolkit : */
        java.awt.Toolkit toolkit = java.awt.Toolkit.getDefaultToolkit();
        /** lecture de l'image : */
        Image image = toolkit.getImage(url);
 
        //BufferedImage image = ImageIO.read( /* File, URL ou InputStream */ );
        JImagePanel jp = new JImagePanel(image, 10, 0, true, true);
 
        jPanel1.add(jp);
        jPanel1.updateUI();
    }

Et voici le code du layout

Ci quelqu'un a une idée qu'il n'hésite surtout pas car la je ne sais vraiment plus quoi faire.

Ou peut être avec une solution plus simple.
Je précise que je suis en JAVA 6

Merci encore.
