How to add authentication info in java client?

Question

How to configure authentication in a java client, I tried creating new Authenticator object & calling it is set Default method, but I am still getting the following error:

java.io.IOException: Authentication failure
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1096)
    at UrlProxy.main(UrlProxy.java : 54)

Please let me know if I need to set any other additional properties. I am opening the connection to my target site using HttpUrlconnection class.

在我的情况下，问题似乎是，服务器期望使用NTLM代理，而我以明文形式发送凭据，更改此选项后即可正常工作。
