Code to apply texture a raw image?

Question

i tried loading a raw image using the code i wrote below.
can anybody please help me debug this code.
i can only see a black and white strip on the entire screen with this.
import javax.swing.*;
import javax.swing.event.*;
import java.awt.image.*;
import java.awt.*;
import javax.media.j3d.*;
import javax.vecmath.*;
import com.sun.j3d.utils.geometry.*;
import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.image.TextureLoader;
import java.io.*;
public class TexTry extends JFrame
     Image img;
     public static void main(String arg[])
          new TexTry();
     public TexTry()
          img=null;
          Container c=getContentPane();
          readImage();
          if(img==null)
               System.exit(1);
          SimpleUniverse u=new SimpleUniverse();
          //c.add(u);
          BranchGroup bg=new BranchGroup();
          Background back=new Background();
          back.setApplicationBounds(new BoundingSphere( new Point3d(0.0,0.0,0.0), 200.0 ));
          Appearance app=new Appearance();
          Texture tex=new TextureLoader(img,this).getTexture();
          app.setTexture(tex);
          BranchGroup bgGeometry = new BranchGroup();
          Sphere sphere = new Sphere( 1.0f,
Primitive.GENERATE_TEXTURE_COORDS |
Primitive.GENERATE_NORMALS_INWARD, app );
          bgGeometry.addChild( sphere );
          back.setGeometry( bgGeometry );
          bg.addChild(back);
          u.addBranchGraph(bg);     
          //setSize(500,500);
          //show();
     public void readImage()
          try
               FileInputStream f=new FileInputStream(new File("himg.raw"));
               int size =f.available();
               byte b[]=new byte[size];
               f.read(b);
               byte[] gray=new byte[256];
               for(int i=0;i<256;i++)
                    gray=(byte)i;
               ColorModel cm=new IndexColorModel(8,256,gray,gray,gray);     
               img=createImage(new MemoryImageSource(640,480,cm,b,0,640));
          }catch(Exception e)
               System.out.println("Error:"+e);

Have you tried this code with another image that you know does work - just using a textureLoader to load in a gif or jpg for example? If the problem isn't with the loading then it is likely your viewPlatform is in a funny place or can't see the entire shape for one reason or another.
