Error Running Sample LWJGL Game

[snowboard4food]

Heres the result when I try to run the space invaders game:
[tylervh@localhost lwjgl-linux-0.98]$ java -cp .:jar/lwjgl.jar:jar/jinput.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_test.jar:jar/lwjgl_devil.jar:jar/lwjgl_util.jar: -Djava.library.path=native org.lwjgl.examples.spaceinvaders.Game -fullscreen

* NoTE: I am running linux and the JDK 1.5.0_05

Any solutions?

Add the res/spaceinvaders dir to the classpath.
