I\'d like to know if there is a jar-file out there that could do the following:
DateMidnight dateInQuestion = new DateMidnight(12,12,2000);
DateChecker.isNat
So far I haven seen any. But what I could suggest for u is to try to link with google calendar api, which from there try to get the holiday calendar through the calendar feed or whatever u call it. From there, process the data and if u want, save it into your database. Afterall, as long as you have a active internet connection, you can use java to connect to the relevant data Even for other languages, I dont think that such direct methods are available.
