The form parameter's primary purpose is input, but you can use it for
output as well under the following circumstances:
* You are forwarding (and not redirecting) to the next page
if the form bean is in request scope.
* The page you forward to expects the bean under the same key
(and in the same scope) that you have declared it in struts-config.xml.
* The output you want to accomplish can be done by simply modifying
properties of the form bean.

The other way to "output" information from an Action is to simply store an
attribute under some key that is used in the destination page -- typically
either by calling request.setAttribute() or session.setAttribute().
