Setup JESI Demos

1) You must have the Oracle Web Cache server up and running on some machine.
   Please see the Web Cache documenation for additional details.

2) For the demo which uses a configuration file, invalidation.jsp, edit 
   the supplied WEB-INF/config.xml to supply the host, port, web cache 
   admin's username and password.

3) For the demo which does not use a configuration file, invalidation2.jsp,
   please edit the jsp example to supply the web cache's host:port and 
   administrator's username and password.

4) Look at the page source (View => Source) to see what the tags generate.
