Title: Problems with a tutorial: java.lang.NoClassDefFoundError
Post by: raziel321 on December 06, 2010, 18:10:49
Hi guys.

I just tried to start with LWJGL and i did a tutorial. This one: http://gpwiki.org/index.php/OpenGL:Tutorials:Java:LWJGL:Introduction (http://gpwiki.org/index.php/OpenGL:Tutorials:Java:LWJGL:Introduction)

The problem comes when i try to start it. It throws an exception:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.lwjgl.opengl.Display
   at main.Main.cleanup(Main.java:107)
   at main.Main.main(Main.java:42)

Before i installed LWJGL by using the java -cp command like told on the homepage and i imported the lwjgl.jar in eclipse

In the VM-Arguments i added: -Djava.library.path=\lwjgl-2.6\native\windows (i just extracted all the stuff into my project folder)

I tried google before, but didn't find anything useful, so i hope someone around here can help.
Thanks in advance,
raziel321

The java.library.path looks wrong.  Did you mean to put a dot at the beginning?
-Djava.library.path=.\lwjgl-2.6\native\windows

If that doesn't work, put the full path (i.e., C:\...\...).  If there are spaces, put quotes: -Djava.library.path="C:\My Documents\...\native\windows"

Also, see this post: http://lwjgl.org/forum/index.php/topic,3600.0.html (http://lwjgl.org/forum/index.php/topic,3600.0.html)

It was the dot. Thanks :)
