Just downloaded today and Iwould like to go through the entire wiki before trying anything on my own. I am using regular jpct not the jpct-ae I ran into problems with hello world here is the class:
import com.threed.jpct.*;


public class HelloWorld {
public static void main(String args[]) throws InterruptedException{

World world = new World();
world.setAmbientLight(0, 255, 0);

TextureManager.getInstance().addTexture("box", new Texture("box.jpg"));

Object3D box = Primitives.getBox(13f, 2f);
box.setTexture("box");
box.setEnvmapped(Object3D.ENVMAP_ENABLED);

box.build();

world.addObject(box);

world.getCamera().setPosition(50, -50, -5);
world.getCamera().lookAt(box.getTransformedCenter());

FrameBuffer buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_NORMAL);
buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
buffer.enableRenderer(IRenderer.RENDERER_OPENGL);

while (!org.lwjgl.opengl.Display.isCloseRequested()) {
        box.rotateY(0.01f);
buffer.clear(java.awt.Color.BLUE);
world.renderScene(buffer);
world.draw(buffer);
buffer.update();
buffer.displayGLOnly();
Thread.sleep(10);
}
buffer.disableRenderer(IRenderer.RENDERER_OPENGL);
buffer.dispose();
System.exit(0);


}

}
and here are the errors

Now I am not 100 percent sure I think one of the errors where it says no lwjgl in library path means i somehow messed up installing the jars not 100% sure though
I am using the Enterprise Edition of Eclipse because I usually work with tomcat
