Connect to MailBox using EWS

Hi,

I am trying to connect to Outlook Mail box using EWS protocol. I am using EWS managed Java API (ews-java-api-2.0.jar). This jar doesn't support the EWS Exchange 2013 version and getting the below exception when i try to run my java program. Is there any other java api version that supports EWS Exchange 2013. Can you please help with this issue.

ERROR:

"Caused by: microsoft.exchange.webservices.data.core.exception.service.remote.ServiceResponseException: The mailbox that was requested doesn't support the specified RequestServerVersion."

Below is the java code:
