Trying a sound recording applet

Question

Hi all.. I am developing an applet that records sound and stores it in a WAV file... The applet is signed and loads in the browser well but it does not give the output, i.e. the WAV file in the specified directory.
Can you please have a look at my code and tell me where Im going wrong?
     public void init()
          b1=new Button("Record");
          add(b1);
          b1.addActionListener(this);
          b2=new Button("Stop");
          add(b2);
          b2.addActionListener(this);
     public void run()
     public void start()
          try
          audioFile = new File(filename);
          audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,44100.0F, 16, 2, 4, 44100.0F, false);
          info = new DataLine.Info(TargetDataLine.class, audioFormat);
          targetType = AudioFileFormat.Type.WAVE;
               targetDataLine = (TargetDataLine)AudioSystem.getLine(info);
               targetDataLine.open(audioFormat);
          catch (LineUnavailableException e)
               msg="Exception occured"+e;
          repaint();
     public void actionPerformed(ActionEvent ae)
          String cmd=ae.getActionCommand();
          if(cmd.equals("Record"))
               try{
               virtual_line           = targetDataLine;
               virtual_audioInputStream= new AudioInputStream(virtual_line);
               virtual_targetType     = targetType;
               System.in.read();
               virtual_outputFile     = audioFile;
               virtual_line.start();
               AudioSystem.write(virtual_audioInputStream,virtual_targetType,virtual_outputFile);
               }catch(Exception e)
                    msg="Exception here"+e;
               msg="Recording..";
          if(cmd.equals("Stop"))
               virtual_line.stop();
               virtual_line.close();
               msg="Stopped";
          repaint();
     public void paint(Graphics g)
          g.drawString(msg,8,80);
}
