title: java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException
body: <p>Trying to work on a game for school and I keep getting a "java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException" when trying to run using eclipse. Any ideas? Here is my code </p>
  
  <pre><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
