public class ImageServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res){
//Set the mime type of the image
res.setContentType("image/jpeg");

try {
// Create an image 200 x 200
BufferedImage bufferedImage = new BufferedImage(200, 200, BufferedImage.TYPE_INT_RGB);

//Draw an oval
Graphics g = bufferedImage.getGraphics();
g.setColor(Color.blue);
g.fillOval(0, 0, 199,199);

// Free graphic resources
g.dispose();

ImageIO.write(bufferedImage, "jpg", res.getOutputStream());
