Java.lang.NoClassDefFoundError: org / lwjgl / LWJGLException

Question

Trying to work on a game for school, and I keep getting "java.lang.NoClassDefFoundError: org / lwjgl / LWJGLException" when I try to run using eclipse. Any ideas? Here is my code

package javagame; import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class Game extends StateBasedGame{ private static final String GAME_NAME = "TEST"; private static final int MENU = 0; private static final int PLAY = 1; public Game(String GAME_NAME){ super(GAME_NAME); this.addState(new Menu(MENU)); this.addState(new Play(PLAY)); }// end constructor public void initStatesList(GameContainer gc) throws SlickException{ this.getState(MENU).init(gc, this); this.getState(PLAY).init(gc, this); this.enterState(MENU); }//end initStateList method public static void main(String[] args) { AppGameContainer appgc; try{ appgc = new AppGameContainer(new Game(GAME_NAME)); appgc.setDisplayMode(640, 360, false); appgc.start(); }//end try catch(SlickException e){ e.printStackTrace(); }//end catch }//end main method }//end Game class 

And the complete error that I get.

 Exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException at javagame.Game.main(Game.java:27) Caused by: java.lang.ClassNotFoundException: org.lwjgl.LWJGLException at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 1 more 

And I'm sure that is correct. http://i.imgur.com/YD77T2C.png

I understood this, so I will publish it in case someone else, having encountered the same problem, stumbles on this page. I had to use an older version of lwjgl.jar, version 2.9.3 worked from the old lwjgl website http://legacy.lwjgl.org/ .
