cal4j - Error at line 1:Unexpected end of file

[beta20]

Hallo zusammen,

ich versuche mich gerade mit cal4j.
Ich bekomme beim Einlesen des Kalenders meines .ics - File aber keine Parser Exception:

net.fortuna.ical4j.data.ParserException: Error at line 1:Unexpected end of file

Mein File enthält folgender Eintrag:

BEGIN:VCALENDAR

Hier mein Code:

public void createEvent(BookingDate bookingDate, Mandatory mandatory, Employee employee)
        throws FileNotFoundException, IOException, ParserException, ConstraintViolationException {

    // Create a TimeZone
    System.setProperty("net.fortuna.ical4j.timezone.cache.impl", MapTimeZoneCache.class.getName());

    TimeZoneRegistry registry = TimeZoneRegistryFactory.getInstance().createRegistry();
    TimeZone timezone = registry.getTimeZone("Europe/Berlin");
    VTimeZone tz = timezone.getVTimeZone();

    String pathMandatoryFile = null;
    String pathEmployeeFile = null;

    // Reading the file and creating the calendar
    Calendar icsCalendar = null;
    FileOutputStream fout = null;

    if (bookingDate.isCreateCalendarMandatoryEntry()) {
        // timezone = registry.getTimeZone(mandatory.getTimeZone());

        pathMandatoryFile = "calendar.ics";
        fout = new FileOutputStream(pathMandatoryFile);
        try {
            FileInputStream fin = new FileInputStream(pathMandatoryFile);
            CalendarBuilder builder = new CalendarBuilder();
            icsCalendar = builder.build(fin);
        } catch (Exception e) {

        }

        if (icsCalendar == null) {
            icsCalendar = createNewCalender(pathMandatoryFile);
        }
    }

    // Creating an event
    java.util.Calendar startCal = java.util.Calendar.getInstance(timezone);
    startCal.set(java.util.Calendar.YEAR, bookingDate.getStartDate().getYear());
    startCal.set(java.util.Calendar.MONTH, bookingDate.getStartDate().getMonth());
    startCal.set(java.util.Calendar.DAY_OF_MONTH, bookingDate.getStartDate().getDate());
    startCal.set(java.util.Calendar.HOUR_OF_DAY, bookingDate.getStartDate().getHours());
    startCal.clear(java.util.Calendar.MINUTE);
    startCal.clear(java.util.Calendar.SECOND);

    java.util.Calendar endCal = java.util.Calendar.getInstance(timezone);
    endCal.set(java.util.Calendar.YEAR, bookingDate.getEndDate().getYear());
    endCal.set(java.util.Calendar.MONTH, bookingDate.getEndDate().getMonth());
    endCal.set(java.util.Calendar.DAY_OF_MONTH, bookingDate.getEndDate().getDate());
    endCal.set(java.util.Calendar.HOUR_OF_DAY, bookingDate.getEndDate().getHours());
    endCal.clear(java.util.Calendar.MINUTE);
    endCal.clear(java.util.Calendar.SECOND);

    net.fortuna.ical4j.model.DateTime dtStart = new DateTime(startCal.getTime());
    net.fortuna.ical4j.model.DateTime dtEnd = new DateTime(endCal.getTime());


    String eventName = bookingDate.getName();
    VEvent meeting = new VEvent(dtStart, dtEnd, eventName);

    // add timezone info..
    meeting.getProperties().add(tz.getTimeZoneId());
    String uidValue = bookingDate.getIdHash();
    meeting.getProperties().add(new Uid(uidValue));

    // Add the event and print
    icsCalendar.getComponents().add(meeting);

    CalendarOutputter outputter = new CalendarOutputter();
    outputter.output(icsCalendar, fout);

}


private Calendar createNewCalender(String filePath) throws ValidationException, IOException {

    // Saving an iCalendar file
    FileOutputStream fout = new FileOutputStream(filePath);

    Calendar calendar = new Calendar();
    calendar.getProperties().add(new ProdId("-//Ben Fortuna//iCal4j 1.0//EN"));
    calendar.getProperties().add(Version.VERSION_2_0);
    calendar.getProperties().add(CalScale.GREGORIAN);

    return calendar;
}

Hat jemand eine Idee?
