RESTful Web services (low-level APIs)

The Calculator tutorial

There are several ways to implement REpresentational State Transfer (REST) Web services. This documentation uses a tutorial based on a calculator Web services application, using the low-level APIs with URIs and verbs.

This tutorial is provided from both the client and the server perspective. In Writing a Web services client application, you learn how to create a client application that accesses the Add function in a calculator Genero Web services server application, with the option to perform the data exchange in either JSON or XML. In Writing a Web Services server application, you learn how to implement the Web service on the server side.
