I think the regular expression version (eg
http://www.javaworld.com/javaworld/jw-12-2000/jw-1201-struts_p.html )
is much better, becouse jou can easely write a client side validation with
the same regexp. ( have it working except for the stupid checkboxes and
radio buttons in ie4+, I keep "losing" my properties)and the regexp object
is part of javascript since version 1.1(I thought, browser NS3+, ie4+).
