JAR + Including Files

[john price]

So I have 16 classes that I can successfully put into a jar. Then, I have two 6 .au files (Sun audio format). I put these 6 files in a folder. When I ran just the jar, it worked. When I moved the folder away (outside the jar), the sound did not work. I used this command:

jar cmf DBall.mf DBall.jar *.class DBall

and then I tf'd it, and all the files showed up. Since the folder is combined with the Jar file (I know this for a fact because it was larger than my class files), it should work. Is there any way that I can put and access that folder that is inside that Jar from one of the class files? For example, I want to be able to call up a sound file from one of the classes while running a Jar.
Currently, I have my "sound player" set up like this...

AudioInputStream sound = AudioSystem.getAudioInputStream(new File("DBall/musicfile.au"));

How do I access the music files inside the Jar?
Thanks,

Instead of using File, use Class.getResouceAsStream() to get a stream and pass it to your getAudioInputStream() method.

It still isn't working...

public void music(){
	try {
	if (!isSet) {
	int jacklndk = (int) ((Math.random() * 5) + 1);
	if (jacklndk == 1) {
    tiny_TIM = "Audio/Cold_Funk.au"; //"Cold_Funk.au
	}
	else if (jacklndk == 2) {
	tiny_TIM = "Audio/Take_the_Lead.au";
	}
	else if (jacklndk == 3) {
	tiny_TIM = "Audio/Surf_Inspector.au";
	}
	else if (jacklndk == 4) {
	tiny_TIM = "Audio/Neo_Western.au";
	}
	else if (jacklndk == 5) {
	tiny_TIM = "Audio/Welcome_to_the_Show.au";
	}
	}
	AudioInputStream sound = AudioSystem.getAudioInputStream(getClass().getResourceAsStream(tiny_TIM)); //new File(tiny_TIM);

    // load the sound into memory (a Clip)
    DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat());
    clip = (Clip) AudioSystem.getLine(info);
	if (clip.isRunning()) {
	clip.stop();
	}
    clip.open(sound);

    // due to bug in Java Sound, explicitly exit the VM when
    // the sound has stopped.
    clip.addLineListener(new LineListener() {
      public void update(LineEvent event) {
        if (event.getType() == LineEvent.Type.STOP) {
          event.getLine().close();
		  if (clip.isRunning()) {
		  clip.stop();
		  }
        }
      }
    });
	clip.start();
  }
  catch (IOException e) {  
    }  
    catch (LineUnavailableException e) {  
    }  
    catch (UnsupportedAudioFileException e) {  
    }  
	isSet = false;
  }
  public void ping(){
	try {
	AudioInputStream sound = AudioSystem.getAudioInputStream(getClass().getResourceAsStream("Audio/Ping.au")); //new File("Audio/ping.au") getClass()

    // load the sound into memory (a Clip)
    DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat()); //,sound.getFormat()
    Clip clip1 = (Clip) AudioSystem.getLine(info);
    clip1.open(sound);

    // due to bug in Java Sound, explicitly exit the VM when
    // the sound has stopped.
    clip.addLineListener(new LineListener() {
      public void update(LineEvent event) {
        if (event.getType() == LineEvent.Type.STOP) {
          event.getLine().close();
        }
      }
    });
    // play the sound clip
	clip1.start();
  }
  catch (IOException e) {  
    }  
    catch (LineUnavailableException e) {  
    }  
    catch (UnsupportedAudioFileException e) {  
    }  
  }

I know for sure these both worked when they were not in a Jar, so the methods' coding is right. Of course I was using a file input instead of a ResourceAsStream...
Please HELP! I've spent probably like 5 hours now trying to figure out the sound system in a Jar...

Assuming that this class is part of a package, you may want to read the javadocs of the Class.getResourceAsStream method.

I see you still think it's a good idea to swallow exceptions silently.

This worked successfully:

private void music(){
	try {
	if (!isSet) {
	int jacklndk = (int) ((Math.random() * 5) + 1);
	if (jacklndk == 1) {
    tiny_TIM = "Cold_Funk.au"; //"Cold_Funk.au
	}
	else if (jacklndk == 2) {
	tiny_TIM = "Take_the_Lead.au";
	}
	else if (jacklndk == 3) {
	tiny_TIM = "Surf_Inspector.au";
	}
	else if (jacklndk == 4) {
	tiny_TIM = "Neo_Western.au";
	}
	else if (jacklndk == 5) {
	tiny_TIM = "Welcome_to_the_Show.au";
	}
	}
	URL url = this.getClass().getClassLoader().getResource(tiny_TIM); //This line was the fix to the problem
	AudioInputStream sound = AudioSystem.getAudioInputStream(url); //new File(tiny_TIM);

    // load the sound into memory (a Clip)
    DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat());
    clip = (Clip) AudioSystem.getLine(info);
	if (clip.isRunning()) {
	clip.stop();
	}
    clip.open(sound);

    // due to bug in Java Sound, explicitly exit the VM when
    // the sound has stopped.
    clip.addLineListener(new LineListener() {
      public void update(LineEvent event) {
        if (event.getType() == LineEvent.Type.STOP) {
          event.getLine().close();
		  if (clip.isRunning()) {
		  clip.stop();
		  }
        }
      }
    });
	clip.start();
  }
  catch (IOException e) {
e.printStackTrace();
    }  
    catch (LineUnavailableException e) {  
	e.printStackTrace();
    }  
    catch (UnsupportedAudioFileException e) {  
	e.printStackTrace();
    }  
	isSet = false;
  }

I was about ready to give up .
