I have spent the better part of two days sorting through this. I developed an applet, using several examples found here and elsewhere, that will play, pause and stop playing an MP3 file. It is very simple and purposely designed that way. I use Eclipse as my development environment and when I run the applet directly from the IDE it runs fine. When I jar the files, sign the jar and deploy the applet through a servlet I get the following:
javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input URL
at javax.sound.sampled.AudioSystem.getAudioInputStream(Unknown Source)
So I am assuming that there is something in the classpath missing that is causing the heartburn to the applet (running in FF5 in Windows 7). Where do I start unpacking the issue? I have the Java Control Panel Console in trace mode but it doesn't show which classes/jars are being accessed as the applet loads. Is there a way to see each class as it is loaded and where (like the -verbose switch) ?
The segment of code that is running is as follows:
