In can be used other ways, but Struts is designed to be a Model 2/MVC
framework. This means you should avoid linking to JSP's directly.
Generally, everything should go through a server-side Action first,
where you can collect whatever data you need for the JSP, and then
forward it through the request context for the JSP to display. The *.do
files are mapped to Struts controller, which calls the server-side
Action. The controller consults the Action Mappings, loaded from
struts-config.xml, to determine which Action to call.
A re-reading of the Users Guide might help you get the big picture.
