TextureLoader: Error loading image file

Question

Hello,
I am trying to load a .gif file to texture map a plane. Well I keep running into a problem loading the .gif file. It just does not load. I get a NullPointerException at the TextureLoader theLoader = new TextureLoader(fileName, observer); I have the .gif file in a folder named TextureImages which is in the same directory as the class that tries to load the file. I have loaded the same .gif file in a different simple test program. But in this program I am having no luck. If anyone has the answer. Please Help.
Here is the class that tries to load the .gif file
package roomPackages.shapes;
//----Import statements
import javax.media.j3d.Texture2D;
import java.awt.Component;
import javax.media.j3d.*;
import javax.vecmath.*;
import com.sun.j3d.utils.image.TextureLoader;
public class CabnetFloorKSD extends Shape3D
//----Member objects and varibles
private double WIDTH; //Cabnet width scaled down by 12
private Appearance theAppearance; //The cabnet appearance
private PolygonAttributes poly_attributes; //Polygon attributes "normal vectors"
private static Component observer;
//----Constructor
// ---------------------------------------------------------- CabnetFloorKSD
// This constructor function builds the Shape3D by using the addGeometry
// function to "glue" together all the QuadArrays. Which represent a
// specfic face of the kitchen floor single door cabnet.
public CabnetFloorKSD(double width, Canvas3D theCanvas)
//----Varibles and objects
this.WIDTH = width; //Getting the width value
theAppearance = new Appearance(); //Cabnet appearance
observer = theCanvas;
loadTextureImage();
//----Building the cabnet functions are here
//----Setting the shapes appearance here
}//end CabnetFloorKSD(double width)
// --------------------------------------------------------- loadTexureImage
// This is where the problem is
public void loadTextureImage()
//----Local varibles and objects
String fileName = "TextureImages/OAK.GIF";
//---- This line is where the NullPointerException happens
TextureLoader theLoader = new TextureLoader(fileName, observer);
/*ImageComponent2D theImage = theLoader.getImage();
Texture2D theTexture = new Texture2D(Texture.BASE_LEVEL, Texture.RGB, 128, 128 );
theTexture.setImage(0, theImage);
theAppearance.setTexture(theTexture);
}//end loadTextureImage()

Hi,
Instead of passing string argument to ImageLoader pass (URL,observer)
ImageLoader(new URL("file:./img.gif",observer);
