I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
     private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
          ServletOutputStream sout = response.getOutputStream();
          for(int n = 0; n < bytes.length; n++) {
               sout.write(bytes[n]);
          sout.flush();
          sout.close();
     }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.
