getCodeBase() in an application problem

[N00Bie]

Hey!

Been wrestling with this for a few hours, but have given up and figured might as well see what brighter minds can shed on this.

Basically, it's an applet that I have (after a lot of googling) converted to an application/applet... one problem is that because of GetCodeBase() it is throwing a nullpointerexception if run as an app. If you run the same thing as an Applet it works perfectly.

What to do?

Heres the code:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.JApplet;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class TestSound6 extends Applet implements ActionListener{
	
    public static void main(String[] args) {
    	
    	 
        //... Create an initialize the applet.
        TestSound6 theApplet = new TestSound6();
        theApplet.init();         // Needed if overridden in applet
        //theApplet.start();        // Needed if overridden in applet
        
        //... Create a window (JFrame) and make applet the content pane.
        JFrame window = new JFrame("Sample Applet and Application");
        window.setContentPane(theApplet);
        window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        window.pack();              // Arrange the components.
        //System.out.println(theApplet.getSize());
        window.setVisible(true);    // Make the window visible.
    }
    public TestSound6() {
        add(new JLabel("This is both an Applet and Application!"));
    }


	
  Button play,stop;
  AudioClip audioClip;

  public void init(){
	
    play = new Button("  Play in Loop  ");
    add(play);
    play.addActionListener(this);
    stop = new Button("  Stop  ");
    add(stop);
    stop.addActionListener(this);
    audioClip = getAudioClip(getCodeBase(), "bark.wav");
  }
  
  public void actionPerformed(ActionEvent ae){
    Button source = (Button)ae.getSource();
    if (source.getLabel() == "  Play in Loop  "){
      audioClip.play();
    }
    else if(source.getLabel() == "  Stop  "){
      audioClip.stop();
    }
  }
}

Because that method is only applicable to Applets and the environment they run in.

getClass().getProtectionDomain().getCodeSource()

Doing a priint out of that I get:
(file:/C:/Users/RyanFuji/workspace/Ryan/bin/ <no signer certificates>)

The problem is (after hours of googling) applets are restricted unless signed, so using an applet call in an app hides/restricts the source from the applet and thus is throwing the NPE
