date - Holidays - is there a java implementation?

Question

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.isNationalHoliday(dateInQuestion, Locale.ITALY);

If there isn't, why? Surely there are lots of properly based rules for the holidays in 99% of the times.

Right now we're mainting a table in our database, with the countries + we have some implementation when it comes to holidays that aren't on the same date every year. We have to add to our implementation for every new country we get new customers.

Could we do this an easier way?

(If there is no such thing in the java sphere, can I port it from some other language?)

I have written the Jollyday API and I'm interested to know what is so 'rough' about it. How can I improve it? Would be great to hear from you. Send me an email to sdiedrichsen@yahoo.de if you like.

By the way. Jollyday is used just the way as the questioner requests it. Please look for yourself.

Cheers, Sven

P.S.: I found a free webservice from Ulrich Hilger which provides detailed worldwide holiday info. Look at api.daybase.eu
