add image to JPanel in NetBeans

i am new to java swing, and i am using now NetBeant for building the GUI using the drag and drop designer built in NetBeans. the problem i am facing now is, i have the below posted code and it was written in Eclipse, and as you see I have a class that extends JPanel and I am adding an image captured from the WEB_CAM to that JPanel.now since i switched to NetBeans, I created the JFrame, JPanel, JButtons using the designer, and in the code i am writing in NetBeans, i do not know how to add the captured image to the JPanel.

in eclipse I created the below posted code in another class, but in NetBeans every thing is generated automatically and i have to do the same work i did in eclipse. i do not know how to add an image to JPanel in NetBeans.

JPanel inEclipse

class FacePanel extends JPanel {
private BufferedImage image;
int count = 0;

public FacePanel() {
    super();
}

public void setFace (BufferedImage img) {
    this.image = img;
}

public void paintComponent(Graphics g) {
    super.paintComponent(g);

    if (this.image == null) {
        System.out.println("image is null");
        return;
    }

    g.drawImage(this.image, 10, 10, this.image.getWidth(), this.image.getHeight(), null);
    g.setFont(new Font("arial", 2, 20));
    g.setColor(Color.WHITE);
    g.drawString("processing frame by frame [ frame: " + ( count++) +  " ]", 150, 150);
}

}

Code in NetBeans

    private void initComponents() {

    jpanel1_Preview = new javax.swing.JPanel();
    btn_Play = new javax.swing.JButton();
    btn_Pause = new javax.swing.JButton();
    btn_Capture = new javax.swing.JButton();

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    jpanel1_Preview.setBorder(javax.swing.BorderFactory.createTitledBorder("Cam_Preview"));

    javax.swing.GroupLayout jpanel1_PreviewLayout = new javax.swing.GroupLayout(jpanel1_Preview);
    jpanel1_Preview.setLayout(jpanel1_PreviewLayout);
    jpanel1_PreviewLayout.setHorizontalGroup(
        jpanel1_PreviewLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0, 0, Short.MAX_VALUE)
    );
    jpanel1_PreviewLayout.setVerticalGroup(
        jpanel1_PreviewLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0, 225, Short.MAX_VALUE)
    );

    btn_Play.setText("play");
    btn_Play.setSelected(true);

    btn_Pause.setText("pause");
    btn_Pause.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(java.awt.event.ActionEvent evt) {
            btn_PauseActionPerformed(evt);
        }
    });

    btn_Capture.setText("capture");
    btn_Capture.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(java.awt.event.ActionEvent evt) {
            btn_CaptureActionPerformed(evt);
        }
    });

  1. Change class FacePanel extends JPanel { to public class FacePanel extends JPanel {, otherwise Netbeans won't be able to create an instance of it.
  2. Do a "Clean and build"
  3. Drag the FacePanel class from the Project explorer onto your form...

Drag
