LeRoux, using com.sun.image.codec.jpeg.* package, here is how you can do it :

Create a java.awt.Image object, get a Graphics object from it.
Draw on this graphics object. Create an encoder for the outgoing
response and encode the image.

    Image image = new BufferedImage (width, height, BufferedImage.TYPE_INT_RGB);
    graph = image.createGraphics();
    // Draw onto this Graph object whatever you like.
    JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder
      (response.getOutputStream());
    encoder.encode (image);

That should do it!
