I'm using Exchange 2007, Coldfusion 9, and EWS API 1.2 to send an email;

<cfobject type="Java" class="microsoft.exchange.webservices.data.ExchangeService" name="service">

<cfobject type="Java" class="microsoft.exchange.webservices.data.ExchangeVersion" name="version">
<cfset service.init(version.Exchange2007_SP1)>

<cfobject type="Java" class="microsoft.exchange.webservices.data.WebCredentials" name="credentials">
<cfset credentials.init("z@x.com","password")>
<cfset service.setCredentials(credentials) />
<cfobject type="Java" class="java.net.URI" name="uri">
<cfset uri.init("https://owa016.msoutlookonline.net/EWS/Exchange.asmx?wsdl")>
<cfset service.setUrl(uri) />
<cfobject type="Java" action="create" class="microsoft.exchange.webservices.data.EmailMessage" name="message">
<cfset message = message.init(service) />
<cfset message.SetSubject("EWSTest")>
<cfset messageBody = CreateObject("java", "microsoft.exchange.webservices.data.MessageBody")>
<cfset messageBody.init("My EWS test message again")>
<cfset message.SetBody( messageBody )>
<cfset message.ToRecipients.Add("v@gmail.com") >

<cfset message.SendAndSaveCopy() >

And that works just fine.  But when I try to create an appointment;

<cfobject type="Java" class="microsoft.exchange.webservices.data.ExchangeService" name="service">

<cfobject type="Java" class="microsoft.exchange.webservices.data.ExchangeVersion" name="version">
<cfset service.init(version.Exchange2007_SP1)>

<cfobject type="Java" class="microsoft.exchange.webservices.data.WebCredentials" name="credentials">
<cfset credentials.init("z@x.com","password")>
<cfset service.setCredentials(credentials) />
<cfobject type="Java" class="java.net.URI" name="uri">
<cfset uri.init("https://owa016.msoutlookonline.net/EWS/Exchange.asmx?wsdl")>
<cfset service.setUrl(uri) />
<cfobject type="Java" class="microsoft.exchange.webservices.data.ExchangeService" name="appointment">
<cfset appointment.Start = createDateTime(Year('2014/03/29'), Month('2014/03/29'), 
 Day('2014/03/29'), Hour('09:00'), Minute('09:00'), 0)>
<cfset appointment.End = createDateTime(Year('2014/03/29'), Month('2014/03/29'), 
 Day('2014/03/29'), Hour('10:00'), Minute('10:00'), 0)>
<cfset appointment.Subject("Dentist Appointment")>
<cfset appointment.Body = "The appointment is with Dr. Smith.">
<cfset appointment.Save(SendInvitationsMode.SendToNone)>

I get the following error;

START

java.lang.NoSuchFieldException: START
	at coldfusion.runtime.StructBean.bindName(StructBean.java:243)
	at coldfusion.runtime.Scope.put(Scope.java:74

And when I use setStart I get a similar error.

I'm not finding a solution anywhere.
