That said, I usually validate twice, once in the Presentation tier and another time in the Business Logic, and I almost never use or even rely on JavaScript, but do strict server-side validation for that's a secure area (while JavaScript can be easily turned off). IMHO it's preferable to have the user spend an additional roundtrip in case of inconsistent data and issue some consolidated warnings in red than pre-checking on the client tier via JavaScript which ends up in a nameless message box. So for me, the Validator generally is a good thing (and crucial when using DynaActionForms), but upon finding out it also has definite lackings when doing complex validation, I dropped the entire DynaActionForm approach and went back to traditional ActionForms. For I found that I finally was spending more time on Validator XML definitions than it takes to generate the entire ActionForm class itself (Oracle JDev and NetBeans have a really useful Beans editor here) and just code the necessary validation code by hand. The advantage is that I can see what's happening directly in the Debugger instead of endlessly interpreting log files and adapting boring XML definitions. But it's a matter of taste, after all, as always.
