Configuration steps are:

1. Configured http://yy.yyyy.yyy.yy URL in the cloud connector
2. Configured generated virtual host and port in the destination service
3. Created connectivity service instance
4. Passing proxy object as created in Connectivity host and port

String result = "";

HttpURLConnection conn = null;

Kindly help us.

I would suggest you deploy HTML5UserAPIforCF with the needed adjustments so you can call the SOAP Endpoint via the destination you have. So get rid of any complexity and check first if you can reach the on premise service via the Cloud Connector.
