Empty vcalendar

[kriegfrj]

I'm trying to write a servlet that returns a ics file.

There are times when the generated caller
Calendar covers a period that doesn't have any events. Is there a way to generate ics with iCal4J that represents an empty vcalendar? From memory I tried it and got a runtime exception warning me about the empty vcalendar component.

If you use the CalendarOutputter class, you can specify if you want to apply validation or not:

CalendarOutputter out = new CalendarOutputter(false);
out.output(calendar, writer); // where writer is the target, e.g. StringWriter, etc.

That should allow an empty calendar to be generated.
