Why does content.setLayout() generate runtime error?

Question

Hi all.
Can some guru please explain to me why this code is generating following runtime error:
java.lang.Error: Do not use SampleView.setLayout() use SampleView.getContentPane().setLayout() instead
     at javax.swing.JApplet.createRootPaneException(Unknown Source)
     at javax.swing.JApplet.setLayout(Unknown Source)
This is the top level TopLevelMenu.java which calls SampleView.java
public void init()
    // java code
    public void actionPerformed(ActionEvent aevt)
        SampleView sampleview = new SampleView();  // <-- OKAY so far
}And here is the snippet for SampleView.java
public class SampleView extends JApplet
    public SampleView()
      Container content = getContentPane();
      content.setLayout(newBorderLayout());  // <-- RUNTIME ERROR HERE
}Instead of just correcting my code, could you please explain to me what is wrong with it?
TIA :-)

Thanks, but that was a typo, I'm still getting this runtime error!
I tried several different ways e.g.
public void init()
    Container content = getContentPane();
    JPanel headerPane = new JPanel(new BorderLayout());
    SampleView sampleview = new SampleView();
    headerPane.add(sampleview, BorderLayout.NORTH);
    content.add(headerPane);
public SampleView()
  // etc
  return;
}throws the same runtime error! Very puzzled!
