You can define a forward in the Struts config file that refers to an
action, e.g.

        <forward name="something" path="/Something.do"/>

        ...

        <action path="/Something" ... />

Then your action can do this:

        return mapping.findForward("something");

You need to establish a strategy for organising actions around pages,
otherwise you will get yourself in a knot. For example, do you have an
action that populates the request with the required data for the view
(i.e. the JSP), forward to that view, then have another action that
processes the submit? Or do you combine the two actions into one, using
parameter derived from the form button to choose your course through a
single action.

Have a look at this, particularly the sections starting at "Two actions,
one form":

Also, try some searches on "action chaining", e.g.
