[Building Sakai] Calendar Events for a site

[Joaquín Marqués Alós]

I use this code to get calendar events. This is an example of code:


java.util.Calendar cal = new
java.util.GregorianCalendar(getUserTimeZone(sessionManager.getCurrentSessionUserId()));

long initTime = cal.getTimeInMillis();
long duration = xxxx; /// period to get events. In milliseconds, but I am
not sure exactly

TimeRange range = timeService.newTimeRange(initTime, duration);

String ref = calendarService.calendarReference(siteId,
SiteService.MAIN_CONTAINER);
Calendar c = calendarService.getCalendar(ref);

for(CalendarEvent event : (List<CalendarEvent>)c.getEvents(range, null))
{
    ...
}


private TimeZone getUserTimeZone(String userId)
{
    TimeZone m_timeZone = null;

    try
    {
        m_timeZone = TimeZone.getDefault();

        Preferences preferences = preferencesService.getPreferences(userId);
        ResourceProperties properties =
preferences.getProperties(TimeService.APPLICATION_ID);
        String timeZone = properties.getProperty(TimeService.TIMEZONE_KEY);

        if (timeZone != null && !timeZone.equals(""))
            m_timeZone = TimeZone.getTimeZone(timeZone);
    }catch(Exception e)
    {
        log.warn("getUserTimeZone -> "+e);
    }

    return m_timeZone;
}
