JMF player and a selected file/mpg

Question

Does anyone know how to change this piece of code so a JMF player can run when a file/mpg is selected.
final File directory = new File(".");
    File[] files = directory.listFiles();
    for(int x = 0; x < files.length; x++)
      if(files[x].isFile()) dim.addElement(files[x].getName());
     btn2.addActionListener(new ActionListener()
           public void actionPerformed(ActionEvent ae)
             int selectedIndex = list.getSelectedIndex();
             if(selectedIndex < 0)
               JOptionPane.showMessageDialog(null,"Please select file");
             else
               File fileToDelete = new File((String)list.getSelectedValue());
               if(fileToDelete.delete()) dim.removeElementAt(selectedIndex);
               }}});

I don't understand?
On the program that I use it's works.
When I put a button, the video close, and the I open an another by launching this method:
public void openFile(String filename)
     String mediaFile = filename;
     // URL for our media file
     URL url = null;
if(player!=null)
player.stop();
player.deallocate();
desktop.removeAll();
repaint();
try
     // Create an url from the file name and the url to the
     // document containing this applet.
     if ((url = new URL(mediaFile)) == null)
          Fatal("Can't build URL for " + mediaFile);
          return;
     // Create an instance of a player for this media
     try
          player = Manager.createRealizedPlayer(url);
catch (NoPlayerException e)
          Fatal("Error: " + e);
catch (CannotRealizeException e)
catch (MalformedURLException e)
     Fatal("Error:" + e);
catch (IOException e)
     Fatal("Error:" + e);
     if (player != null)
     this.filename = filename;
     jmframe = new JMFrame2(player, filename);
//jmframe.setSize(200,100);
     desktop.add(jmframe);
I hope that It could Help you.
You can find an exemple quite similar on this site , the name of the file is: MDIApp.java
