iCal4J tutorial

sessionEvent.getProperties().add(new Summary("xxxx summary));

 iCal4J is library to generate/parse Calendar ics file.

 

Its simple to use until you know what to do, the docs is not good at all.

 

Here is a few simple steps

 

 

• 1. Create Calendar object - the big Calendar object matching ics file
• populate some compulsory fields:

net.fortuna.ical4j.model.Calendar cal = new net.fortuna.ical4j.model.Calendar();
cal.getProperties().add(new ProdId("-//xxx org //iCal4j 1.0//EN"));
cal.getProperties().add(Version.VERSION_2_0);
cal.getProperties().add(CalScale.GREGORIAN);

 

• Create VEvent Object - which hides all detail about a certain event (including recurring ones)

VEvent sessionEvent = new VEvent();

 

• Remeber there are lots of object inheriting Property so just create varied properties and add to the event property list
• For example, create summary for the event

 

sessionEvent.getProperties().add(new Summary("xxxx summary"));

•  create start time

	String dateAsICal4JString = "20110813T113000"; // date+time format
	sessionEvent.getProperties().add(new DtStart(dateAsICal4JString));

•  ADD recurring rule

Recur recur = new Recur(Recur.WEEKLY, 20); // 20 is repeat count
recur.getDayList().add(new WeekDay("WE"));
RRule rule = new RRule(recur);
sessionEvent.getProperties().add(rule);

 

 

 

• At least, add the VEvent created to Calendar component

cal.getComponents().add(sessionEvent);

 

Its very simple right? First time look at it, shit,don't know what to do

 

Here is long code reference where I got the ideas
