我们正在使用EWS Java API在Java应用程序上使用Outlook日历。我在EWS上遇到身份验证问题。
我在由机架空间提供的cloud Outlook帐户上尝试了该应用程序，并且一切正常，因此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("[email protected]");
msg.send();
} catch (Exception e) {
e.printStackTrace();
}
}
}
机架空间的网址是:
https://connect.emailsrvr.com/EWS/Exchange.asmx当我输入该帐户的用户名和密码后，该帐户就可以使用了，我看到控制台吐出了这个名称:Apr 05, 2013 1:40:28 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme
INFO: NTLM authentication scheme selected
我们的客户端使用的是ExchangeVersion.Exchange2007_SP1，而Rackspace使用的是ExchangeVersion.Exchange2010。但是，当我使用客户端提供的凭据(用户名，密码和url)时，出现此错误:

我找不到此问题的任何解决方案。请提供您认为我可以通过EWS进行身份验证的任何信息。是什么导致这些异常？
最佳答案
我遇到了完全相同的错误，浪费了5个小时来修复它。我的结论是，您不应在尝试使EWS代码库正常工作上浪费更多时间，EWS代码很困惑，您必须深入研究才能修复该库中的错误。
我决定使用javax.mail实现来实现我所需要的。
