Try this code:
SimpleHttpConnectionManager theConnectionManager = new
SimpleHttpConnectionManager();
HttpClient theClient = new HttpClient( theConnectionManager );
//Set The Proxy Host Configuration
HostConfiguration theHostConfiguration = theClient.getHostConfiguration();
theHostConfiguration.setProxy( "YOUR_PROXY_SERVER_NAME",
YOUR_PROXY_SERVER_PORT_AS_int );
//Get State
HttpState theState = theClient.getState();
//Set The Credentials
theState.setProxyCredentials( null, null, new NTCredentials(
"PROXY_USERS_NAME", "PROXY_USERS_PASSWORD", "YOUR_MACHINE_NAME" ,
"YOUR_NETWORK_DOMAIN" ) );
/***NOTE*****
PROXY_USERS_NAME = is the name that YOU! need to authenticate yourself
through proxy server
PROXY_USERS_PASSWORD = is the password
*************/
PostMethod thePostMethod = new PostMethod( "www.theregister.co.uk" );
thePostMethod.setRequestBody( "YOUR DATA AS STRING IF ANY" );
theHttpResponseCode = theClient.executeMethod( thePostMethod );
if ( theHttpResponseCode == HttpStatus.SC_OK )
{
...
...
...
..
Let me know if this helps

Subject: Problems with NTLM authentication
Hi
I'm new to HttpClient and I was hoping someone could help use the NTLM
authentication correctly. I have
the neccassary permissions because I can get to the site through Internet
Explorer without any problem.
After seeing some discussion of problems with with NTLM in -rc1 I've
upgraded to -rc2 but I still cannot
connect to the host www.theregister.co.uk.
I'm getting the error message;
"WARNING: No credentials available for the 'null' authentication realm at
www-proxy2.uk.int.atosorigin.com"
My code is below. I'm probably doing somethnig stupid, but I'd be grateful
for any pointers as to
what I'm doing wrong
Regards
Roger Varley
