I see that I can validate a Date with the Validator framework,
but don't know how to apply it in my case.

my bean has separate variables for day - month - year
(it is not one string)
I have three fields because he had to choose the date with a select html tag for the day, a select html tag for the month and an input field for the year.

How can I validate this date now ?

well, in that case you have to write validation rule.

Logic is

if month = feb and date = 29 OR 30 OR 31 , block user/ show error
Date cannot be over 28 for month Feb!

another option is to
let the user select a date from calendar. There are lots of open source calendars. In that case you would have only "required" rule and thats it.
