You can create images such as jpegs by using the Java2D class BufferedImage, and then encode it using javax.imageio or JAI :

http://java.sun.com/products/java-media/jai/http://java.sun.com/j2se/1.5.0/docs/guide/imageio/

After creating the image, then set the content type of the servlet :

response.setContentType("image/jpeg");

and write out your jpeg byte[] array data :

response.getOutputStream().write(bytes);
