JFileChooser & ActionListener

[tima]

Hey again,

My project consists of one Applet and an MP3Player class.
I'm using a JFileChooser to play an mp3 song. The problem is that in my
applet I have 2 buttons: start + stop buttons ... I must add an
ActionListener to those buttons, but it is not working with inner classes.
Any other way to make it ?

The start button calls the function "play()" located in the MP3Player class
The stop button calls the function "stop()" located in the MP3Player class

  boolean openFile(){

   JFileChooser fc = new JFileChooser ();
   fc.setDialogTitle ("Open File");
   fc.setFileSelectionMode ( JFileChooser.FILES_ONLY);
   fc.setCurrentDirectory (new File ("."));
   fc.setFileFilter(fMp3Filter);
   int result = fc.showOpenDialog (this);
   if (result == JFileChooser.CANCEL_OPTION) {
   return true;
   }
   else
   if (result == JFileChooser.APPROVE_OPTION) {
   fFile = fc.getSelectedFile ();
   nowplaying.setText(fFile.getName());
   MP3Player mp3=new MP3Player(fc.getSelectedFile().getAbsolutePath());

   start.addActionListener(new ActionListener() {
   public void actionPerformed(ActionEvent evt) {
   if(evt.getSource() == start)
   mp3.play();
   }});

   stop.addActionListener(new ActionListener() {
   public void actionPerformed(ActionEvent evt) {
   if(evt.getSource() == stop)
   mp3.stop();
   }});

 ....

Error given : "MediaPlayer.java": Error #: 480 : local variable mp3 is accessed from within inner class; needs to be declared final at line 95, column 4
