I noticed that the source for OpenAL is a bunch of interfaces to "C language funcs". Apple provides a Java native version of its CoreAudio I believe, so perhaps you could implement the OSX version of OpenAL in pure java.
(That is, unless you've already done so and the C interface is windows-specific)

"No, it runs, but it doesn't sound right."
I'm running OSX on a G4. (not sure where I can find what my sound card is) I'm using the latest OSX build.
The program runs perfectly, but the sound played back is only static with certain wav files.
lesson1/wavdata/FancyPants.wav plays clearly.
lesson2/wavdata/Footsteps.wav plays static. Footsteps.wav is not corrupted because I can play it in other programs.
