Response to: WebDav & NTLM
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.
  
  
  - Dennis.

  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.
