Cross language conversion of JsonRpcService

[m1heng]

Here is the background:
Most of our services are using jsonrpc4j to create a JsonRpcService Class which would be published and used by other Java services.
But for other languages like Node.js, we can only invoke pure HTTP requests without type definitions.
I just wonders if there is any way or tools that JsonRpcService Class (published as a jar) can be converted to packages in other languages like Node.js.
