LWJGL/OpenAL example does not compile

just wanted to make my first steps with lwjgl/openal and tried to compile the example on
http://www.lwjgl.org/documentation_openal_01.php

but i get this error:

Lesson1.java:41: cannot resolve symbol
symbol : class WaveData
location: package openal
import org.lwjgl.test.openal.WaveData;

i mounted all lwjgl jars i could find in my ide.
what am i missing?


  import org.lwjgl.util.WaveData

thx. works now.

sry, updated site
