NTLM authentication

Actually I don't know whether I've chosen the right category, but I think this one suited the best for my question.
Can anyone tell me whether Java > 1.4 can support NTLM v2 authentication ? I've read here that it does, but I can't get it to work.
My code looks like this :
Authenticator.setDefault(new MyAuthenticator(login,password));
URL url = new URL(httpPage);
URLConnection connection = url.openConnection();
PasswordAuthentication pa =
connection.getURL().getPort(), connection
.getURL().getProtocol(), null,

MyAuthenticator is a class that extends Authenticator, and of course
implements properly (rather sure) getPasswordAuthentication() method.

The problem is that I always get Unauthorized access :/. I'm quite sure
that I'm providing good login and password.
The thing I think is causing the problem is "NTLM" argument that I'm
providing in requestPasswordAuthentication. API says, that there should
be a schema there, but I don't know what the schema for the NTLM is.
Can anyone help me?

Btw. If I put there "NTLM1" for example, I get the same response
(Unauthorized accesss).
