Hi

I would like to play a sound file like this

Media buzzer = new Media(MainApplication.class.getClassLoader().getResource("sounds/buzzer.mp3").toExternalForm());
MediaPlayer mediaPlayer = new MediaPlayer(buzzer);
mediaPlayer.play();

and I was suprised to get this exception:

Exception in thread "JavaFX Application Thread" java.lang.UnsupportedOperationException: Unsupported protocol "bundleresource"
	at com.sun.media.jfxmedia.locator.Locator.<init>(Locator.java:233)
	at javafx.scene.media.Media.<init>(Media.java:391)

I was suprised that Media does not support the protocol "bundleresource" when Image does. Of couse I can figure out the location of file and use File.toURI().toString() to get the URI I can pass on to Media.

I am wondering why this pattern would work for an Image but not for a Media class? Does e(fx)clipse provide this protocol for Image (and could this be extended for Media) or is this built into JavaFX?

Cheers
Christoph

No we are not doing anything special for Image which most likely uses
Java-Streams whereas the media stuff directly delegates to the native
code to fetch the stream from an URL. Looking at the code the only 2
supported protocols are file: and http:

Thanks for the Info. I think it supports the jar: protocol too. I am using FileLocator.resolve(url) to convert the protocol which also works in an exported jar bundle.

Hi,

There's no generic support for that:
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=483378
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=483390

See https://wiki.eclipse.org/Efxclipse/Runtime/Recipes#Media
