Hi,
Im trying to connect to an URL using java codes, however i hit the error:

java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost/mail

Below is my codes.


I have also tried using setRequestProperty(), but will still hit the same error.

Did i miss out anything in my code?

Thanks.
