executable jar + audioclips

Question

I've been getting this exception when running the app from an executable jar:

java.lang.UnsupportedOperationException: Unsupported protocol "rsrc"
       at com.sun.media.jfxmedia.locator.Locator.<init>(Locator.java:233)
    at com.sun.media.jfxmediaimpl.NativeMediaAudioClip.<init>(NativeMediaAudioClip.java:53)
    at com.sun.media.jfxmediaimpl.NativeMediaAudioClip.load(NativeMediaAudioClip.java:63)
    at com.sun.media.jfxmediaimpl.AudioClipProvider.load(AudioClipProvider.java:66)
    at com.sun.media.jfxmedia.AudioClip.load(AudioClip.java:135)
    at javafx.scene.media.AudioClip.<init>(AudioClip.java:83)
    at com.aqua.snakesandladders.view.gamepieces.Token.<init>(Token.java:70)"

here's Token.java:70, which is the cause of this:

AudioClip bounceSound = new AudioClip(getClass().getResource("/sounds/bounce.wav").toExternalForm());

"bounce.wav" is located in "resources" source folder @ "sounds" subfolder.

Running the app in eclipse throws no exception @ this point + plays the AudioClip when needed.

Help! :(

Have you checked what `getClass().getResource("/sounds/bounce.wav").toExternalForm()` produces? Maybe it is something that the constructor does not like. ( thats what `javafx.scene.media.AudioClip.(AudioClip.java:83)` says) — FibreFoX, Dec 23 '16 at 16:15
it likes it when i run it in eclipse, but not when i run it from the executable jar? — Igal Klebanov, Dec 24 '16 at 17:40
same syntax gives no issues on both IDE & jar when it comes to images or css files. — Igal Klebanov, Dec 24 '16 at 17:43
Can you provide some mcve for this? http://stackoverflow.com/help/mcve — FibreFoX, Dec 26 '16 at 10:44

The following is the code that throws Exception:

this.scheme = this.scheme.toLowerCase();
if (this.scheme.equals("jar")) {
  URI subURI = new URI(this.uriString.substring(4));
  this.protocol = subURI.getScheme();
  if (this.protocol == null) {
    throw new IllegalArgumentException("uri.getScheme() == null!");
  }

  this.protocol = this.protocol.toLowerCase();
} else {
  this.protocol = this.scheme;
}

if (!this.protocol.equals("file") && !this.protocol.equals("http")) {
  throw new UnsupportedOperationException("Unsupported protocol \"" + this.protocol + "\"");
} else {
  if (this.protocol.equals("http")) {
    this.canBlock = true;
  }

  this.uri = uri;
}

If you print your uri here you can see something like:

rsrc:foo.bar.Main

Which is a invalid uri as javafx told you.

Manifest

So why you uri is invlaid?

If you open your Manifest file, you will find some entries which eclipse added, like：

...
Rsrc-Class-Path: ./
Rsrc-Main-Class: net.xxx.main.Main
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader

and here is where the rsrc comes from.

Advice

Update your manifest file to be like original manifest, i.e. remove rsrc started entry and change main class to your class;
Not use eclipse to package your jar, using tools like maven, gradle
Use Intellij :)
