Re: [MLUG] Java Sound Problem

[Jason McIntosh <EMAIL:PROTECTED>]

Um, the url you'd probably want to use, if a windows client is running 
the applet, is this:
file://C:\directory\myfile.wav
Sometimes, just having the wav file in the classpath doesn't work.  
Primarily due to how the applet system works, and the protections 
there, and what it can and can't see.  You could try loading a File 
object,

File my_file = new File("C:\directory", "myfile.wav");
if (my_file.exists())
	System.out.println("Found the file!");
else
	throw new Exception("ERROR!  File not found!");
AudioClip clip = java.applet.Applet.newAudioClip(file.toURL());

Try something like that.  I'm not sure of the exact parameters on the 
clip.  Further, usually if it can't open the file or understand it's 
format, check to make sure that it is throwing an error, and make sure 
you're catch statements are actually outputing to system.err or 
system.out the various errors.  Right now, it still sounds like an 
issue with your settings.  If you want to email me the .java files, I 
can take a look real quick and probably fix it for you.
