Subject Re: Struts action populate a list then display the jsp
Date Mon, 01 Oct 2001 17:43:16 GMT


Ah! but what if your action redirects to a view JSP, and then they book mark that?
Are we talking the same lingo here. What do you mean by link to action mappings ?

The best thing is to link only to ActionMappings and never to JSPs. Then
they can only bookmark the mapping. If anything is missing, it is much
easier to handle that from an Action than from a JSP.
