httpclient: Behined ISA proxy server and need to reach Internet site

[Ashraf Fouad]

Dears,

My client machine accesses the Internet through a proxy, I'm writing
http client program to download page source from the Internet, here is
my code:

 

    HttpClient client = new HttpClient();

    HostConfiguration hostConfiguration = client.getHostConfiguration();

    hostConfiguration.setProxy( "192.168.0.200", "8080" );

 

    HttpState state = client.getState();

    Credentials proxyCredentials = new UsernamePasswordCredentials(
"username", "password" );

                                 

    state.setCredentials( "rayasoftware.com", "192.168.0.200",
proxyCredentials );

 

    PostMethod cnnPost = new PostMethod( "http://www.cnn.com"; );

    cnnPost.setDoAuthentication( true );

    

    client.executeMethod( cnnPost );

    System.out.println( cnnPost.getStatusLine().toString() ); 

    // release any connection resources used by the method

    cnnPost.releaseConnection();

 

 

 

I'm getting the following message:




HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires
authorization to fulfill the request. Access to the Web Proxy service is
denied.  )

[WARN] HttpMethodBase - -No credentials available for the 'null'
authentication realm at 192.168.0.200

What is wrong with my code.

 

Thanks, Best regards
