Print from a jsp in linux

Question

Hi all,
I've got a problem with a web application... :(
I have deployed that application on a Tomcat 5 server, jre 1.4.2, the same version I used to build the war file.
When I tested the application on a Windows Server everything was ok.
the application list from a directory all tiff files present, display the one chosen by the user on the scrren. and, pushing the proper button, print the document.
I used java.awt.print package in order to do this.
well, when I run the application on linux I have
java.awt.HeadlessException
     sun.print.PSPrinterJob.printDialog(PSPrinterJob.java:465)
after I give thefilename to print to the printer class.
the structure is:
jsp page which contains the commands and the viewer area, in which I display the image (the src of the image is a displayingservlet).
pushing the "print" button, the filename & path of the image displayed is given to the printTheDocument() method.
my print class:
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.Component;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Color;

            try{

                ImageDecoder decoder=ImageCodec.createImageDecoder("tiff",ss,null);
                int number=decoder.getNumPages();
                RenderedImage[] image=new RenderedImage[number];
                for(int i=0;i<number;i++){
                    image=decoder.decodeAsRenderedImage(i);
PlanarImage image2=PlanarImage.wrapRenderedImage(image[page]);
BufferedImage image3=image2.getAsBufferedImage();
mt.addImage(image3,0);
try{
mt.waitForID(0);
}catch(InterruptedException ex){ex.printStackTrace();}
g2.drawImage(image3,
(int)(0.25 * POINTS),
(int)(0.25 * POINTS),
(int)(6 * POINTS),
(int)(8.5 * POINTS),
this);
ss.close();
}catch(IOException ex){ex.printStackTrace();}
return (Printable.PAGE_EXISTS);
in windows it works properly.
any idea???
thanks, Camilla

You need to set CATALINA_OPTS -Djava.awt.headless= true in your setenv.sh
