Calling JSON service in Scheduled script

Hello Friends,

I have a requirement to call the JSON web service that i have deployed on a remote server and to pull the data into NS script for further processing. I am using JayRock library to create the JSON service.
The normal way to consume this type of services in client application is to call load the proxy script for the service(this is done at runtime) and the call the method on the proxy object.i.e.

  document.write("<script type=\"text/javascript\" src=\"myservice.ashx?proxy\"></script>");
    window.onload = function()
    {
    var a = new myservice();
