Check following testcase:

import static org.junit.Assert.assertEquals;

import java.io.ByteArrayOutputStream;
import java.io.OutputStream;
import java.util.Calendar;

import org.junit.Test;

import microsoft.exchange.webservices.base.BaseTest;
import microsoft.exchange.webservices.data.core.EwsServiceXmlWriter;
import microsoft.exchange.webservices.data.property.complex.recurrence.pattern.Recurrence.WeeklyPattern;

public class RecurrenceWriterTest extends BaseTest{

  @Test
  public void testWeeklyPattern() throws Exception {
    OutputStream output = new ByteArrayOutputStream();
    EwsServiceXmlWriter writer = new EwsServiceXmlWriter(exchangeServiceMock, output);

    WeeklyPattern weekly = new WeeklyPattern();
    Calendar c = Calendar.getInstance();
    c.setFirstDayOfWeek(1);
    weekly.setFirstDayOfWeek(c);
    weekly.writeElementsToXml(writer);

    assertEquals(c, weekly.getFirstDayOfWeek());
  }
}

You are going to get this ServiceXmlSerializationException as below screenshot:

Hi @stulife, I could reproduce it. It's a bug in the java-ews-api. It's currently difficult with fixes, cause this repo is nearly dead. There is a plan to move/fork a 'community' repo. But here is a qucikfix, hopefully you can use it: `/**

    new DayOfTheWeekCollection();

private DayOfTheWeek firstDayOfWeek;

@leftstick: Thanks, for your unit test. I added some testcases on my fork, I hope to merge it as soon as possible to share this with you!

Thanks, Jan

[stulife]

it's right ,with my solution as same,thank's

[lpld]

Hey, I understand that the repo is almost dead, but is there any chance this will be fixed anytime soon?

[leftstick]

@lpld you can check the fix @OS-JaR provided. And re-compile the source code, publish it to your own maven repo.

You and your team should fetch this library from your own maven repo instead. That's what we did in our team

[lpld]

@leftstick Thanks for the answer. Probably that's what we'll do in the future too, 'cause it's not the first issue with this library that we face. For now I felt like it's easier to me to just extend couple classes, create new Recurrence PropertyDefinition with this issue fixed and replace it in AppointmentSchema via reflection.
