Chamar video sem filechooser usando jmf.[Resolvido]

Saudações a todos, estou querendo chamar o video sem passar pelo file chooser, estou usando o exemplo do deitel
está funcionando tudo corretamente, só q pra eu implementar na minha aplicação não posso usar filechooser.
segue os códigos:

Classe MediaPanel

[code]package Teste;
import java.awt.BorderLayout;
import java.awt.Component;
import java.io.IOException;
import java.net.URL;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;
import javax.swing.JPanel;

public class MediaPanel extends JPanel
{
public MediaPanel( URL mediaURL )
{
setLayout( new BorderLayout() ); // use a BorderLayout

  // Use lightweight components for Swing compatibility
  Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true );
  
  try
  {
     // create a player to play the media specified in the URL
     Player mediaPlayer = Manager.createRealizedPlayer( mediaURL );
     
     // get the components for the video and the playback controls
     Component video = mediaPlayer.getVisualComponent();
     Component controls = mediaPlayer.getControlPanelComponent();
     
     if ( video != null ) 
        add( video, BorderLayout.CENTER ); // add video component

     if ( controls != null ) 
        add( controls, BorderLayout.SOUTH ); // add controls
     
     mediaPlayer.start(); // start playing the media clip
  } // end try
  catch ( NoPlayerException noPlayerException )
  {
     System.err.println( "No media player found" );
  } // end catch
  catch ( CannotRealizeException cannotRealizeException )
  {
     System.err.println( "Could not realize media player" );
  } // end catch
  catch ( IOException iOException )
  {
     System.err.println( "Error reading from the source" );
  } // end catch

} // end MediaPanel constructor
} // end class MediaPanel[/code]

Classe MediaTest

[code]package Teste;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.JFileChooser;
import javax.swing.JFrame;

public class MediaTest
{
// launch the application
public static void main( String args[] )
{
// create a file chooser
JFileChooser fileChooser = new JFileChooser();

  // show open file dialog
  int result = fileChooser.showOpenDialog( null );

  if ( result == JFileChooser.APPROVE_OPTION ) // user chose a file
  {
     URL mediaURL = null;


     
     try
     {
        // get the file as URL
        mediaURL = fileChooser.getSelectedFile().toURL();
     } // end try
     catch ( MalformedURLException malformedURLException )
     {
        System.err.println( "Could not create URL for the file" );
     } // end catch

     if ( mediaURL != null ) // only display if there is a valid URL
     {
        JFrame mediaTest = new JFrame( "Mangue Media Player" );
        mediaTest.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        
        MediaPanel mediaPanel = new MediaPanel( mediaURL );
        mediaTest.add( mediaPanel );
        
        mediaTest.setSize( 300, 300 );
        mediaTest.setLocation(500, 100);
        mediaTest.setVisible( true );
     } // end inner if
  } // end outer if

} // end main

} // end class MediaTest[/code]

Preciso chamar a classe MediaTest atráves de um botão dentro da minha aplicação.
Desde já obrigado, no aguardo de ajuda e informações.

Problema resolvido. tive que alterar a classe MediaTest.
Segue abaixo o código alterado:

Classe MediaTest

[code]package Teste;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.JFileChooser;
import javax.swing.JFrame;

public class MediaTest
{
// inicia a aplicação
public static void main( String args[] )throws MalformedURLException
{
String video = “/C:/caminho_do_arquivo/nome_do_arquivo.mpeg”;
File arquivo_video = new File(video);

     URL mediaURL = null;

     try{
           mediaURL = arquivo_video.toURL();
     }catch(MalformedURLException malformedURLException){
           System.err.println("Não foi possível criar um URL do arquivo");
     }
     if(mediaURL != null){
          MediaPanel mediaPanel = new MediaPanel(mediaURL);
     }

     if ( mediaURL != null ) // exibi somente se houver uma URL válida
     {
        JFrame mediaTest = new JFrame( "Mangue Media Player" );
        mediaTest.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        
        MediaPanel mediaPanel = new MediaPanel( mediaURL );
        mediaTest.add( mediaPanel );
        //System.out.println("URL: "+mediaURL);
        mediaTest.setSize( 300, 300 );
        mediaTest.setLocation(500, 100);
        mediaTest.setVisible( true );
     } 
  } 

}[/code]

Obrigado a todos.
