Can't get the example to work.

[mournblade]

Hi, trying to migrate from the "old" jollyday, but having problems with the example code. Using 0.27 via maven, but when I run this method:
private HolidayManager getHolidayManager() { if(holidayManager == null) { holidayManager = HolidayManager.getInstance(ManagerParameters.create(SWEDEN)); } return holidayManager; }

I get an error:

java.lang.IllegalStateException: Cannot instantiate datasource instance because there is no implementations
at de.focus_shift.jollyday.core.datasource.ConfigurationServiceManager.instantiateDataSource(ConfigurationServiceManager.java:33)

Any idea what this is? Pointers appreciated.

You need to use the Jackson or jaxb dependency and not the core.

Allright, I see it now, thanks. Total noob question, but why? I'm not using it to parse anything, literally just want the holidays as in the example? Is it to read config files from disc?

[derTobsch]

The holidays are described in XML files. So we need Jackson or jaxb to parse them.

Missing configuration 'manager.impl'. Cannot create manager.

public static boolean isHoliday(LocalDate date, String countryCode) {
final HolidayManager holidayManager = HolidayManager.getInstance(ManagerParameters.create(HolidayCalendar.GERMANY));
final Set holidays = holidayManager.getHolidays(Year.of(2022));
return true;
}

Please help me, what could be happening?

you need to add a xml dependency like jollyday-jaxb or jollyday-jackson, see https://github.com/focus-shift/jollyday?tab=readme-ov-file#xml-binding-libraries
