Subclassing ActionMapping definitely sounds like the most straight forward
approach. I'm kind of
surprised there isn't any error thrown as it is. I would also think that
Struts would allow a default
handler for if no matches occur. Subclassing does seem to be the easy route
though.

Subject: Re: [cinjug-users] Struts question: how do you handle an undefined
ActionForward value?
Good question.
You're basically returning a null ActionForward from your Action, because
the page is not found by the ActionMapping. It *is* because you have a
programming error in your app.
You could subclass ActionMapping to return an error page if a forward is
not found (to help you as the programmer). What do other struts folks do?
