java ews_如何验证EWS Java API

我们使用EWS

Java API在

Java应用程序上使用outlook日历.我在EWS上遇到了身份验证问题.

我尝试使用由rackspace提供的云Outlook帐户上的应用程序,一切正常,所以我知道凭据是准确的.

这是代码：

import java.net.URI;

import java.net.URISyntaxException;

import microsoft.exchange.webservices.data.*;

public class TestClass {

public static void main(String[] args) {

TestClass obj = new TestClass();

obj.testMethod();

}

public void testMethod() {

ExchangeService service = new ExchangeService(

ExchangeVersion.Exchange2007_SP1);

ExchangeCredentials credentials = new WebCredentials("username",

"password");

service.setCredentials(credentials);

try {

service.setUrl(new URI("https://domain/EWS/Exchange.asmx"));

} catch (URISyntaxException e) {

e.printStackTrace();

}

EmailMessage msg;

try {

msg = new EmailMessage(service);

msg.setSubject("hello world");

msg.setBody(MessageBody

.getMessageBodyFromText("Sent using the EWS API"));

msg.getToRecipients().add("[e-mail]");

msg.send();

} catch (Exception e) {

e.printStackTrace();

}

}

}

rackspace的网址是：https：//connect.emailsrvr.com/EWS/Exchange.asmx

当我为这个帐户输入用户名和密码并且它有效时,我看到控制台吐出这个：

Apr 05, 2013 1:40:28 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme

INFO: NTLM authentication scheme selected

我们的客户端正在使用ExchangeVersion.Exchange2007_SP1,而Rackspace正在使用ExchangeVersion.Exchange2010但是当我使用客户端提供的凭据(用户名,密码和URL)时,我收到此错误：

Apr 05, 2013 1:49:13 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme

我找不到任何解决这个问题的方法.请提供您认为我可以通过EWS验证的任何信息.造成这些例外的原因是什么？
