Here's how I normally handle this scenario.  In the Action class that
handles this form submit:
* Perform whatever task is requested
* Remove the form bean session attribute
* Forward to whatever JSP page is appropriate.

When the <struts:form> tag of the form sees that there is no form bean
there, it will create a new one (with whatever default values you have
defined in the class itself) and store it in the session.  From the user's
perspective, that's a new blank form.

In general, it is a good practice to delete form beans from the session when
you are through with them -- otherwise they just sit there occupying memory
until the session is invalidated or timed out.
