Tuscany supports JSON-RPC as a protcol for use with SCA services by using the <binding.jsonrpc> element in your Application composite. This enables remote web browser clients to easily make RPC style calls to server-side SCA components.
User Stories
- A web browser client application invoke a remote SCA Service using JSON-RPC and the invocation return business objects in JSON format.
- e.g. Retrieve catalog items
- A SCA component can define a reference to a remote SCA Service and use JSON-RPC for the invocation.
- e.g. A catalog aggregator invoke various catalog services using JSON-RPC and aggregate the returned items into a single response
- A client application invoke a SCA Service using JSON-RPC and the invocation returns a business exception.
- e.g. Empty catalog throws a Busines Exception. Business Exception should properly propagate and display nicely to client.
- A client application invoke a SCA Service using JSON-RPC and the invocation returns a runtime exception.
- e.g. Try to retrieve catalog items from a catalog service that is un-available. Runtime exception properly propagate and display nicely to client.
- A client application needs to access a service exposed trough JSON-RPC binding that requires authentication.
- e.g. make sure if nobody can get to the catalog if it's not authenticated

There are two samples showing using <binding.jsonrpc>, one which uses the Dojo Toolkit on the client, and another which uses the Tuscany scaDomain.js script. The samples are helloworld-dojo and helloworld-jsonrpc.

The current Tuscany SCA runtime supports <binding.jsonrpc> and <binding.dwr> which provide similar functionality. The differences are:
These differences should be resolved by the Tuscany SCA 1.0 release. |
