Selenium-Phantomjs Proxy Setting Issue

[Pragati]

I am using Phantomjs1.9.7 and Selenium 2.39.0  (Java) for web testing , the problem is ghost driver is not able to get the URL  , for 1st line driver.getURL(..) , its showing "Proxy Authorization  Required" , i tried all possible ways of setting the proxy (Setting System proxy , setting proxy through capabilities , using phantomjs CLI arguments , adding authentication keys in Register-HKEY_CURRENT_USER ) but no luck . How to solve the proxy setting issue for ghost driver ?? Thanks in advance...
