code:
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
ValidateImage image = new ValidateImage();
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader ("Expires", 0);
try {
BufferedImage im = image.creatImage();
request.getSession().setAttribute(
HttpSessionKeys.ValidateImage, image.sRand);
ImageIO.write(im, "JPEG", response

} catch (Exception e) {
e.printStackTrace();

}
(The class ValidateImage generate a object of java.awt.image.BufferedImage)
thanks.
