I am developing a CGI script that creates a GIF file on the fly as
output.
The following program (with associated classes) works if  it is run with
the
worstation open and with DISPLAY (X-11) set.    But the

getGraphics(..)

call hangs if DISPLAY is not set.  Of course no DISPLAY can be set for
a CGI program !!!

Any comments, ideas will be deeply appreciated.

                         BufferedImage.TYPE_INT_RGB);
         System.err.print("one");
         //  getGraphics() hangs if no DISPLAY
         Graphics off_g = off.getGraphics();
         off_g.drawRect(20,20,100,70);
         FileOutputStream out = new FileOutputStream("rect.gif");
         GifEncoder en = new GifEncoder(off, out);
         en.encode();    // sends GIF to file out
         return;
    }
}
