Thread: Can I set the contentPane of JF to be JApplet?

Could I do something like this:

 
   public class SneakyShortCut extends javax.swing.JFrame
   {
 
      private javax.swing.JApplet ja;
      private javax.swing.JButton b1, b2;
 
      public SneakyShortCut()
      {
 
         super("JFrame with a JApplet as content pane");
 
         ja = new javax.swing.JApplet();
 
         b1 = new javax.swing.JButton("Button 1");
 
         b1.addActionListener(
               new java.awt.event.ActionListener() {
 
                  public void actionPerformed(java.awt.event.ActionEvent e)
                  {
 
 
                     java.net.URI uri = null;
 
                     try
                     { 
                        uri = new java.net.URI("C:/Users/Wenguin/My Documents/Sleep Away.mp3");
                     }
 
                        catch(java.net.URISyntaxException urise)
                        {
                           javax.swing.JOptionPane.showMessageDialog(null, "Error!", "Could not find file!", javax.swing.JOptionPane.ERROR_MESSAGE);
 
 
                        }
 
                     java.net.URL temp = null;
 
                     try
                     {
                        temp = uri.toURL();
 
                     }
 
                        catch(java.net.MalformedURLException murle)
                        {
                           javax.swing.JOptionPane.showMessageDialog(null, "Error!", "Could not find file!", javax.swing.JOptionPane.ERROR_MESSAGE);
 
 
                        }
 
 
 
 
                     ja.play(temp);
 
 
 
 
                  }});
         b2 = new javax.swing.JButton("Button 2");
 
 
         ja.setContentPane(new javax.swing.JPanel());
 
         ja.getContentPane().setLayout(new java.awt.GridLayout(2,1));
 
         ja.getContentPane().add(b1);
         ja.getContentPane().add(b2);
 
         setContentPane(ja);
 
         setVisible(true);
 
         setDefaultCloseOperation(EXIT_ON_CLOSE);
 
 
 
      }
 
 
      public static void main(String[] args)
      {
 
         new SneakyShortCut();
 
 
      }
 
 
   }

If I can do this, without major complications, then I can use the JApplet to work as a media player.

It appears I can do it, though when I try the URI.toURL() it won't accept it and later throws a NullPointerException as the variable uri throws the MalformedURLException.
