calendar.set(2012, Calendar.NOVEMBER, 1, 0, 0, 0);
Date startDate = calendar.getTime();
calendar.set(2012, Calendar.DECEMBER, 1);
Date endDate = calendar.getTime();

MailAddressCollection attendees = new MailAddressCollection();
attendees.add(new MailAddress("attendee_address@domain.com", "Attendee"));
WeeklyRecurrencePattern expected = new WeeklyRecurrencePattern(3);

Appointment app = new Appointment("Appointment Location", "Appointment Summary", "Appointment Description",
									startDate, endDate,
									new MailAddress("organizer_address@domain.com", "Organizer"), attendees, expected);

//Attach a file from disc to this appointment
File file = new File("OutputXLS.xls");
FileInputStream fis = new FileInputStream(file);

Attachment att = new Attachment(fis, file.getName());
String savedFile = "appWithAttachments.ics";
app.save(savedFile, AppointmentSaveFormat.Ics);

Appointment app2 = Appointment.load(savedFile);
System.out.println("Total Attachments: "  + app2.getAttachments().size());
for (int i=0; i< app2.getAttachments().size();i++)
	att = app2.getAttachments().get(i);

        //Save the attachment to disc
