Saminda,
This credentials provider will cause HttpClient to enter an infinite
loop if the given credentials are not valid for some reason (due to a
type, for instance).
Essentially all you have to do to get the same net effect is this:
String username = "username";
String password = "password";
String host = "somehost";
String realm = "realm";
NTCredentials creds = new NTCredentials(
username, password, host, realm);
httpclient.getState().setCredentials(
new AuthScope(host, AuthScope.ANY_PORT),
creds);
NTCredentials is a super class of UsernamePasswordCredentials, so the
same set of credentials will work with Basic and Digest schemes.
Give it a shot.
Hope this helps
