I'm trying to get org.newdawn.slick.tests.SoundTest to run but am getting the following exception.

Code:

Wed Oct 17 00:20:41 BST 2007 INFO:Slick Build #179

The command I'm running is:

Code:
java -cp lib/slick.jar:lib/lwjgl.jar -Djava.library.path=lib org.newdawn.slick.tests.SoundTest


I'd be grateful for any ideas as to what I might be doing wrong.

Thanks.

You seem to be missing the DLL files for OpenAL.

If you mean libopenal.so, it's in the lib directory along with all the other native stuff.

I fixed this by downloading LWJGL 1.1.2 and copying across jinput.jar, lwjgl.jar and the Linux natives.
