Mark,
I don't think you should be creating beans that extend HttpServlet. Extend
HttpServlet to create a servlet that you use to populate a bean (which might
extend an object like Vector or Hashtable for example), and then pass the
bean to the JSP file (setAttribute / <BEAN>) so that it can be referenced as
you wish.
That's the model we use. It isn't the only way.
