Recently, I started working on ical4j. So, thought will post some of the my initial learnings. I will keep updating this as I learn more.
I created a project with maven. Here is how my pom.xml looks
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.sunilpk</groupId>
<artifactId>Ical4jProto</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>Ical4jProto</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.mnode.ical4j</groupId>
<artifactId>ical4j</artifactId>
<version>1.0.4</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
Once that is done, now its times to learn some basics. Like creating a Calendar.
package com.sunilpk.ical4jproto;
import net.fortuna.ical4j.model.Calendar;
import net.fortuna.ical4j.model.property.ProdId;
import net.fortuna.ical4j.model.property.Version;
import net.fortuna.ical4j.model.property.CalScale;
/**
*
*/
public class CreateCalendar {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Calendar calendar = new Calendar();
calendar.getProperties().add(new ProdId("-//CALENDAR//iCal4j 1.4.0//EN"));
calendar.getProperties().add(Version.VERSION_2_0);
calendar.getProperties().add(CalScale.GREGORIAN);
System.out.println("The Calendar is: " + calendar);
}
}
The output of the program:
The Calendar is: BEGIN:VCALENDAR
PRODID:-//CALENDAR//iCal4j 1.4.0//EN
VERSION:2.0
CALSCALE:GREGORIAN
END:VCALENDAR
Similarly, an .ics file can be read
package com.sunilpk.ical4jproto;
import java.io.FileInputStream;
import java.io.IOException;
import net.fortuna.ical4j.data.CalendarBuilder;
import net.fortuna.ical4j.data.ParserException;
import net.fortuna.ical4j.model.Calendar;
import net.fortuna.ical4j.util.CompatibilityHints;
/**
*
*/
public class ReadCalendar {
public static void main(String[] args) {
try {
FileInputStream fin = new FileInputStream("src/main/java/com/sunilpk/ical4jproto/invite.ics");
CalendarBuilder builder = new CalendarBuilder();
Calendar calendar = builder.build(fin);
System.out.println("Product Id: " + calendar.getProductId());
System.out.println("Method Id: " + calendar.getMethod());
} catch (IOException e) {
System.out.println("IO Exception.. " + e);
} catch (ParserException pe) {
System.out.println("Parse Exception. " + pe);
}
}
}
The output of the above program could be similar to following.
Product Id: PRODID: Calendar-Provider
Method Id: METHOD:CANCEL
