Action maps back to same page...best way to reset ActionForm?

[Rick Schumeyer <rs...@ieee.org>]

I have jsp containing a form to add employees.  This submits to an 
action that adds the new employee to the database, and then forwards 
back to the add employee page so that more employees can be added.  
Currently, when I get back to the jsp the ActionForm still contains the 
original data, but at this point I want a blank action form.

If I am using an ActionForm (as opposed to a DynaActionForm), what is 
the best way to clear the form?
*  I can manually clear all the fields in the action before calling 
findForward
* Should I override the ActionForm reset method (and call reset before 
findForward) ?
* Should I use a DynaActionForm instead?  (Would that provide any advantage)
* Is there some other obvious solution that I'm missing?

BTW, this is struts 1.3.5.  The action configuration declares request scope.

Rick,

If you perform a redirect instead of a forward from the action, the new
page will have a new form, because the data will not carry over (because
you are using request scope).

As a bonus, if the user reloads the page, they will not be resubmitting
the form post that adds an employee.
