.Mp3 file in java using notepad

I know this is a recurring question. check the original here or here .

So my code is to only copy a copy:

import javafx.scene.media.*;

class Gui {
  public static void main(String[] args) {
    try{
        Media hit = new Media("skin.mp3");
        MediaPlayer mediaPlayer = new MediaPlayer(hit);
        mediaPlayer.play();
    }catch(Exception e){
        e.printStackTrace();
    }
  }
}

The exception that I get is:

java.lang.IllegalArgumentException: uri.getScheme() == null!
        at com.sun.media.jfxmedia.locator.Locator.<init>(Locator.java:217)
        at javafx.scene.media.Media.<init>(Media.java:364)
        at Gui.main(gui.java:6)

I compile and run it correctly, i.e. include the file jfxrt.jarin the classpath

Note. I use notepad instead of any IDE.

So can someone tell me the reason IllegalArgumentException

Thankx

UPDATE : using file://e:/skin.mp3it worked fine, but left me with another exception:

MediaException: MEDIA_INACCESSIBLE : e
        at javafx.scene.media.Media.<init>(Unknown Source)
        at Gui.main(gui.java:6)

So, if you can highlight this exception.

By the way, I checked the song without ruining it, because it plays great in vlc.
