A simpler alternative to that approach would be to simply make an
additional setter method in you bean (and getter if appropriate) for
your Date member which takes a String, parses it (preferably according
to the user's Locale) and sets your Date member. The form data should
be first validated, otherwise you'll get a ParseException.
I hope this is useful to you.
