Answer 1

and to add to matt's post:
          in the servlet init() method trace out some debug to ensure that new
          versions of your servlet are actually being deployed:
          ..init() {
          System.out.println( getServletName() + " was deployed at " + " new
          Date(System.currentTimeMillis()) );
