Mixing HTML and JPEG image on one output page

[Kenny G. Dubuisson, Jr.]

I'm trying to write a servlet that draws a chart and put's some HTML info
about the chart on a page.  For a test, I got a servlet to draw a blue
rectangle (proving my graphics and JPEG encoding worked) in my browser.  The
problem I'm having is that I can't seem to add HTML to the page; it only
draws the rectangle when I send the graphics as a single JPEG image.

Does anyone know how to mix an embedded JPEG image and regular HTML?  I've
attached my little test servlet below for reference.  Thanks,
Kenny

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.awt.*;
import java.awt.image.*;
import com.sun.image.codec.jpeg.*;

public class GraphicsTest extends HttpServlet
{
   private static final int WIDTH = 650;
   private static final int HEIGHT = 650;

   public void doGet(HttpServletRequest request,
      HttpServletResponse response) throws ServletException, IOException
   {
      // open the output and set the type to JPEG
      ServletOutputStream out = response.getOutputStream();
      response.setContentType("image/jpeg");

      // create a blank image
      BufferedImage image = new BufferedImage(WIDTH, HEIGHT,
         BufferedImage.TYPE_INT_RGB);
      Graphics2D g2 = image.createGraphics();
      g2.setColor(Color.blue);
      g2.fillRect(0,0,WIDTH,HEIGHT);

      // encode the output to JPEG
      JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
      encoder.encode(image);

      // send the output out
      out.flush();
      out.close();
   }
}
