[JAVA] Inserire immagine TIFF

import java.io.*;
import javax.media.jai.*;

public class Tiff extends Applet
{
private BufferedImage tiffImage=null;

public void init()
{
String imageName=getParameter("image");
File theFile=null;
try
{
theFile = new File(imageName);
}catch(Exception e) {e.printStackTrace();}

if(theFile.isFile())
{
PlanarImage jaiImage=JAI.create("tiff",imageName);
tiffImage=jaiImage.getAsBufferedImage();
}
}

public void paint(Graphics g)
{
g.drawImage((Image)tiffImage,5,5,this);
}
}

mi da un'exception sulla drawImage()

io devo solamente leggere un'immagine tiff e disegnarla.
