Regarding UAT Deployment and Access Box Api from UAT

Hi All, Using box Api in java, when trying to make connection in UAT along with PROXY its not not working, Any suggestions how to pass PROXY to box API.........

Code base:

BoxAPIConnection client = new BoxAPIConnection(DEVELOPER_TOKEN);
proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(InetAddress.getByName("http://proxy-xxx.apple.com"), "xxxx"));
client.setProxy(proxy);
