Yensen,


Can't help with #2, but I am currently using NTLM and WebDav. Here is some sample code that should help:




NTCredentials creds = new NTCredentials(userName, password, hostAdd, "" );
HostConfiguration hostConfig = new HostConfiguration();
hostConfig.setHost(hostAdd); //Not url, just ip address or fully qualified DN
HttpURL host = new HttpURL("http://" + hostUrl);
WebdavResource res = new WebdavResource(host, (Credentials)creds, WebdavResource.DEFAULT, DepthSupport.DEPTH_1);


Hope this helps.

    Bill,

    Tried with the code given above:

    NTCredentials creds = new NTCredentials(userName, password, hostAdd, "" );
    HostConfiguration hostConfig = new HostConfiguration();
    hostConfig.setHost(hostAdd); //Not url, just ip address or fully qualified DN
    HttpURL host = new HttpURL("http://" + hostUrl);
    WebdavResource res = new WebdavResource(host, (Credentials)creds, WebdavResource.DEFAULT, DepthSupport.DEPTH_1);


    However, I see an authentication-warning message saying "Already tried to authenticate with null authentication realm at <exchange server name>, but still receiving: HTTP/1.1 401 Access Denied". Proceeding furhter with the method "WebdavResource.list ();" gives a NullPointerException.

    Am I doing something wrong? Do I need to setup my Tomcat to redirect the authentication to MS Exchange server? Please help.

    Thanks in advance.

      Bill,

      Finally I solved the puzzle.

      Before trying with the above code snippet, I tried to access my Exchange server through Outlook Web Access (OWA) from my browser. While doing so, the browser saved the prompted user-id (Administrator) and password in the password manager.

      Hence, for the next time, when I tried to connect to the Exchange server using your code snippet, I got the following error message -

      "Already tried to authenticate with null authentication realm at ${Exchange server name}, but still receiving: HTTP/1.1 401 Access Denied".

      To overcome this, I just cleared the saved passwords in the browser settings. After doing so, the program works like a charm...!

      Thank you.

      Regards,
      Dennis.
