المحلول

That using the stringlenth validator you can validate the length of the string. Check the stringlength validator.

And using the date validator you can validate the date format. Check the date validator.

If you want to validate datetime picker using validate() you should use the logic that is to parse the value returned by the picker using SimpleDateFormat if you are not using other date time libraries like JODA and don't care about timezone then you should create ThreadLocal parser for datetimes.
