Anirban, I have a cron job working that successfully connects to an Exchange Web Service via JAXWS protected by NTLMv2. I can post my code if you think it will help. Dave

My code is something like this :- ..... * if (tcp.getProxyUser() != null && tcp.getProxyPassword() != null) { * * // add basic authentication header for the proxy* * authstring = "Basic "* * + XMLUtils.base64encode((tcp.getProxyUser() + ":" + tcp * * .getProxyPassword()).getBytes());* * }* * * * //try 3 times* * for (int i = 0; i <= 2; i++) {* * * * repondChallange(out, connect, authstring);* * * * if (processProxyResponse(is)) {* * return socket;* * }* * Header[] headers = extractHeaders(is);* * authstring = getAuthString(tcp, port, host, headers);* * while (is.available() > 0 && is.read() > 0) {* * // read all* * }* * if (closeConnection(headers)) {* * socket.close();* * socket = new Socket(tcp.getProxyHost(), proxyPort, null, 0);* * socket.setTcpNoDelay(true);* * socket.setSoTimeout(0);* * is = new BufferedInputStream(socket.getInputStream(), 2048);* * out = new BufferedOutputStream(socket.getOutputStream(), 2048);* * }* ..... The RespondChallange Method writes to the output stream with headers like User-Agent: , Proxy-Authorization: . The method* processProxyResponse(is) *checks for the reply from the proxy server and returns true only if status code of 200 is encountered. The getAuthString method basically is a generic method which returns the string based on the authentication Scheme selected and serves as the value for *Proxy-Authorization: *header :- ..... * ConnectMethod method = new ConnectMethod();* * authstring = authscheme.authenticate(credentials, method);* ..... My code works fine for Basic,Digest Authentication but fails for NTLM scheme with Error code :- 407. Using the JCIFS library it works though. Just wanted to know if this is a known problem with apache commons httclient ?? Is there a workaround for this ,since i am not too keen on using JCIFS library ??
