Web Service to JSON-RPC Transformation

During the last years JavaScript Object Notation Remote Procedure Call (JSON-RPC) emerged as the de facto standard for service calling on mobile devices. Unfortunately many enterprise services are still only available as traditional Web Service accessible via Web Services Description Language (WSDL) and Simple Object Access Protocol (SOAP). In this paper we introduce the Web Service to JSON-RPC adapter tool which offers JSON-RPC ports matching the SOAP ports in a WSDL-based web service definition. The adapter automatically translates JSON-RPC requests incoming on these ports to a responding SOAP message and forwards it the SOAP server. The SOAP response is translated back to JSON-RPC and delivered to the original client. Our adapter enables software developers to use a JSON-RPC client which is well supported on mobile platforms to access SOAP-based Web Services without altering the server nor requiring additional software on client side.
