In fact, the best practice is to always preface a page with an action. You end
up with actions that prepare information for a page, and actions which process
information for a page. The actions which process the page information will
always have had the form bean created before you get to the action. However,
the actions which prepare the page information may have to manually create the
form bean and put it into the appropriate scope.
Note that the welcome page for an application would normally be something like
"index.jsp", which does nothing but forward to an action to start the
application. You can't preface the welcome page with an action, but you can
make it do nothing but go to an action to prepare the real first page.
Look at the source code for the "example" application for some examples of
using the form bean. The user guide also talks about the control flow with
respect to form beans.
