Failed to load image into Jpanel

[mr_bemar]

Hi,

I want to load a simpel image into a JPanel.
I use the following way:

public class MyClass{
 private Icon Bild = new ImageIcon("http://today.java.net/jag/old/green/duke/T4.gif");
    JLabel jLabel2 = new JLabel(Bild);

private void init (){
  jLabel2.setBackground(Color.white);
        jLabel2.setForeground(Color.white);
        jLabel2.setBorder(BorderFactory.createEtchedBorder());
        jLabel2.setPreferredSize(new Dimension(100, 70));
        jLabel2.setIconTextGap(0);
        jLabel2.setLabelFor(contentPane);
        jLabel2.setIcon(Bild);
}
}

I think the code is correct but the image doesn't appear.
Do anyone recognize my bug?

Thanks in advance

Greetings
Ben
