Subject Re: Struts action populate a list then display the jsp
Date Mon, 01 Oct 2001 16:52:17 GMT
the idea is not to have your JSPs available for bookmarking.  if all your links point to action
mappings (e.g., *.do URIs) and you do forwards to all your JSPs, then a JSP will never be
visible in the URL pane of the user's browser.  that way, s/he can never bookmark a JSP which
could conceivably be displayed in an
uninitialized state.
