If I were you I would use strings in my form beans (or at least methods or parallel field which accept strings as arguments) and look into third party stuff, i.e. Matt Kruse's date handling javascript. Additionally, I would bypass the validator and validate in my action (that way you would have the text the user entered). It is easy enough to emulate the validator flow of control (just read the mapping and get the 'input' value and forward to it).
