Load a image in JPanel on button click

Question

I have seen many answers regarding this, but nothing seem to solve my problem, I have a jPanel1 and jPanel3 in a tabbed pane (same tab) and when I click a button from jPanel1 then I go to load an image in jPanel3. Here is how I am trying to do the same

jButton1.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {

            System.out.println("In the action");
            try {
                jPanel3.add(new JPanel(){
                    java.net.URL imgURL = this.getClass().getResource( "/resource/images/cd-dvd-icon.png");
                    BufferedImage image = ImageIO.read(imgURL);
                });
                jPanel3.revalidate();
                jPanel3.repaint();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
    });

But I am not seeing any error or the image also. Please help

Finally figured out the problem, have added the layout again as like it is added in the generated code and it worked

jButton3.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
           System.out.println("In the action");
           JLabel imgLabel = new JLabel(new ImageIcon(this.getClass().getResource( "/resource/images/cd-dvd-icon.png")));
            jPanel2.add(imgLabel);
            jPanel2.revalidate();
            jPanel2.repaint();
            jPanel2.setLayout(jPanel2Layout);
            jPanel2Layout.setHorizontalGroup(
                jPanel2Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
                .addGroup(jPanel2Layout.createSequentialGroup()
                    .addGap(24, 24, 24)
                    .addComponent(jButton3)
                    .addGap(59, 59, 59)
                    .addComponent(jToggleButton1)
                    .addGap(50, 50, 50)
                    .addComponent(imgLabel)
                    .addContainerGap(235, Short.MAX_VALUE))
            );
            jPanel2Layout.setVerticalGroup(
                jPanel2Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
                .addGroup(jPanel2Layout.createSequentialGroup()
                    .addGap(33, 33, 33)
                    .addGroup(jPanel2Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE)
                        .addComponent(jToggleButton1)
                        .addComponent(jButton3))
                        .addGap(59, 59, 59)
                        .addComponent(imgLabel)
                    .addContainerGap(368, Short.MAX_VALUE))
            );
        }

    });

You're not adding the image to the panel. Create a JLabel with the image inside and then add the label to jPanel3:

        try 
        {
            JLabel imgLabel = new JLabel(new ImageIcon(this.getClass().getResource( "/resource/images/cd-dvd-icon.png")));
            jPanel3.add(imgLabel);
            jPanel3.revalidate();
            jPanel3.repaint();
        }catch (Exception ex){
            ex.printStackTrace();
        }
