exchangewebservices - How to authenticate EWS Java API -


we using ews java api use outlook calendar on our java application. having authentication issues on ews.

i tried application on cloud outlook account that's supplied rackspace , worked fine know credentials accurate.

here code:

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 ews api"));             msg.gettorecipients().add("test@test.com");             msg.send();         } catch (exception e) {             e.printstacktrace();         }      }  }

the url rackspace is:https://connect.emailsrvr.com/ews/exchange.asmx when put username , password account , works, see console spitting out one: 

apr 05, 2013 1:40:28 pm org.apache.commons.httpclient.auth.authchallengeprocessor selectauthscheme info: ntlm authentication scheme selected

our client using exchangeversion.exchange2007_sp1 whereas rackspace using exchangeversion.exchange2010 when use credentials(username, password , url) our client provided, getting error:

i couldn't find solution issue. please provide info think can authenticated ews. causing these exceptions?

i had exact same errors , wasted 5 hours trying fix it. conclusion should not waste more time on trying ews codebase work, ews code confused , you'll have go in under hood fix bugs in library.

i settled on using javax.mail implementation need. https://stackoverflow.com/a/18043717/445131
