There are two kinds of controller classes, Actions, found in the action directory, and ActionForms found in the data directory.
Struts Actions provide a glue between the View and Model layers and are responsible for processing specific requests. Struts Actions should always extend org.apache.struts.action.Action�.
Struts ActionForms should always extend org.apache.struts.action.ActionForm�.
org.apache.struts.action is the core of the struts framework, providing the "Controller" aspect of a MVC model. See the section on MVC.
TBD - talk about how to go to different actions from the jsp using the hidden thingy
