Help with First Game Blender Models?

I am making a game with an upside down pyramid. This I imported from blender, because there are some details on the pyramid. Anyway, i have a box as a board on which the pyramid stands, and a skybox with some weird magic textures. However, i want to put a texture on the pyramid. I give it a LightState,  MaterialState, and TextureState with my image. However, the texture doesnt show up for some reason. Does anyone know why? Here is my code:

package classes;
import com.jme.image.Texture;
import com.jme.input.InputHandler;
import com.jme.input.KeyBindingManager;
import com.jme.input.KeyInput;
import com.jme.math.Vector3f;
import com.jme.math.Vector2f;
import com.jme.renderer.Camera;
import com.jme.renderer.ColorRGBA;
import com.jme.scene.Node;
import com.jme.scene.shape.Box;
import com.jme.scene.state.TextureState;
import com.jme.system.DisplaySystem;
import com.jme.util.TextureManager;
import com.jme.util.Timer;
import com.jmex.model.XMLparser.XMLtoBinary;
import com.jmex.model.XMLparser.JmeBinaryReader;
import com.jme.math.Quaternion;
import com.jme.scene.state.MaterialState;
import com.jme.light.PointLight;
import com.jme.scene.state.LightState;
import com.jme.util.geom.BufferUtils;
import com.jme.scene.TriMesh;
import com.jme.scene.Skybox;
