Tool is designed to automate routine process so developer makes server calls as they were local functions. This software provides: -automated server wrapper code for accepting calls -automated client code for making calls Only annotated services (functions) on server side will be provided for JavaScript calls. It makes development of server calls easy and robust. Developer doesn't need to care about actual communication between server and client, instead it can focus more on actual problem. Functions that generator makes are making AJAX calls which are very similar to Remote Procedure Calls (RPC). Each function is named (and has parameters named) like as it is on server side. On top of that, adds two more optional parameters, onSuccess and onError for handling these events. Produced code is native for corresponding languages and it doesn't require 3rd party libraries.
