Thanks for quick reply. I only did some hacking (I used to work for
Hacker, Peter the Great-:)
here is what I did on DConnect2.java

< import org.apache.commons.httpclient.HttpMethod;
< import org.apache.commons.httpclient.methods.GetMethod;
< import org.apache.commons.httpclient.HttpClient;

< import org.apache.commons.httpclient.HttpMethod;
< import org.apache.commons.httpclient.Header;
< import org.apache.commons.httpclient.auth.AuthScope;
< import org.apache.commons.httpclient.UsernamePasswordCredentials;
< import org.apache.commons.httpclient.methods.HeadMethod;

< _httpClient.getState().setCredentials(
< new AuthScope("hostname",80),
< new UsernamePasswordCredentials("user", "passwd"));

< Authenticator.setDefault(new MyAuthenticator.MAuthenticator());

< Authenticator.setDefault(new MyAuthenticator.MAuthenticator());
239,240d224
< method.setDoAuthentication( true );
