Alternative for JEC/EWSJ Connector


This third party connector has two version of connector JEC and EWSJ connector former is used to connected to Microsoft Exchage server 2003 (which is not suppport exchange web service) connection happen through WebDev , EWSJ uses EWS provided by the exchange.

We will explore more on EWSJ connector

1)      To integrate with Java applcation with Microsoft Exchange server 2007 SP3
2)      Using  EWS(Exchange web services) provided by Microsoft
3)      SSL enabled 
4)      Standard certificates (generated using a CA) are not self-sighed, and will always work.
5)      In some rare cases, self-signed (test) certificates will not work.
This happens because there is a special mechanism that is part of JEC/EWSJ that kicks-in to enable SSL communication with test certificates, and it does not cover all possible cases
6)      EWSJ connector deployed as part of Application Server.
7)      EWSJ Connector will access the Microsoft provided web service. (https://<exchagehost>/EWS/Exchange.asmx)
8)      Please refer this site for EWSJ connector : www.javaexchangeconnector.com
9) EWSJ is support the most secured ways of communication with Exchange, NTLMv2, NTLM and Digest authentication methods are supported, SSL is used by default.
                Seperatly, all security patches need to be applied to Exchange.
      10) EWSJ Connector provides the API for the Exchange Web Services , So that we call the API from the    java applcation without knowledge of the web service.
 11)  it not open source , JEC / EWSJ Enterprise License - $999 USD 
12 ) It has interface for PowerShell also.

The alternative solution  would be using JavaAPI for EWS provided by Microsoft itself .
