The 'REST' is not a correct name for implemented functionality, since it is just about calling services using HTTP requests and getting responses using JSON. Therefore, it is not the REST. The name should be changed to something else.
The best name would be 'JSONService'. However, this name is already occupied by current JSON invocation tool. For that reason, 'rest' is renamed to 'JSONWebService'. Invocation pat is now 'jsonws'.
