Bug 20200 – (Windows only) Java Sound API throws AccessControlException opening URL when action initiated from Javascript.

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Java

[Glenn Brauen]

The above URL contains an applet that uses Java Sound API to open and play a small .wav file that resides on the originating server of the HTML page (and applet).  The playing of the applet can be triggered through either of two buttons: one implemented by the applet itself and another that invokes a Javascript function that then invokes an applet function.

Running in Safari on windows, clicking the applet button works (the audio file plays) but clicking the javascript button throws the following exception (they execute the same code in the applet):

network: Connecting http://devel0.gcrc.carleton.ca/webkit_JSA_Windows_AccessControlException/spacemusic2.wav with proxy=DIRECT

I have tested on Safari 3.1.2 and the latest webkit nightly (r35406).

Running in any of the following works (both buttons result in audio playing):
- Safari on Mac OS X (10.4)
- Firefox on Mac OS X (10.4)
- Firefox 2 on Windows XP
- Firefox 3 on Windows
- Internet Explorer on Windows

The applet source is linked off the HTML page but I will also attach all of the following to this bug report:
- applet source
- ant build file
- html page
- wav file

If you want to test with this on another machine (the above URL may occasionally be unavailable because it is a development machine), then dump the attachments to a folder, run the ant build, and make the results available through a web server.

I have not attached the wav file.  If you need it, you should be able to grab that from http://devel0.gcrc.carleton.ca/webkit_JSA_Windows_AccessControlException/spacemusic2.wav.

It is an uncompressed wav file.  I used this to avoid audio format conversions and ensure that the test case is as simple as possible.

Java applet support is long gone, closing.
