JSON-RPC implementation

If you have an implementation for JSON-RPC please add it below:

JavaScript

• Pmrpc is an inter-window cross-domain remote procedure call JavaScript library for use within browsers. Pmrpc is an implementation of JSON-RPC using HTML5 postMessage API for message transport.
• There is a JSON-RPC implementations as part of JavaScript O Lait jsolait.
  You can also find some live examples
• The Open Source TelePort Library supports JSON-RPC as well as other RPC protocols.
  Live demos and documentation can be found here.
• JSON-RPC to Java bridge includes a JavaScript client.
• Dojo Toolkit 0.3 implements JSON RPC.
• JSON/XML-RPC Client Implementation which abstracts-away the differences between JSON-RPC and XML-RPC and permits cross-site requests.
• Wakanda implements a JSON-RPC Client in its WAF framework and a JSON-RPC Server (with Server-Side JavaScript?).

C

• JSON-RPC C Bridge. There is also support for GoAhead WebServers.

C++

• JsonRpc-Cpp - GPL v3 library

C#

• Jayrock - .NET and ASP.NET

Erlang

• YAWS JSON-RPC module (HTTP client/server)

Objective-C

• Asynchronous JSON-RPC Service Proxy

Java

• JSON-RPC to Java bridge
• JRP
• jj1 (JSON-RPC HTTP client/server)
• JSON-RPC 2.0 Base is a minimalist implementation, with no framework or transport dependencies
• JSON-RPC 2.0 Console Client for querying, testing and debugging JSON-RPC 2.0 web services
• Simple Java JSON-RPC (com.werxltd.jsonrpc) For exposing methods in existing POJOs via JSON-RPC

Lisp

• CL-JSON - Common Lisp

Lua

• JSONRPC4Lua

Perl

• http://search.cpan.org/dist/JSON-RPC-Common/ is a complete transport agnostic implementation of JSONRPC 1.0, 1.1 and 2.0
• Catalyst using the JSONRPC plugin
• JSON module

Php

• JSON-PHP
• php-json
• PHP-O-Lait
• Phpxmlrpc (in the 'extras' package)
• SCA_SDO Pecl Package
• JSON_RPC_Server, a JSON-RPC implementation in PHP
• JSON/XML-RPC Server Implementation which abstracts-away the differences between JSON-RPC and XML-RPC.

Python

• A python package which implements the JSON-RPC specs. It includes an mod_python handler, a CGIHandler, a TCP server and (soon) a ServiceProxies implementation.
• python-symmetric-jsonrpc implements JSON-RPC over sockets/ssl sockets such that client and server can both call methods on each other (also thread-safe and asynchronous).
• django-json-rpc JSON-RPC server for versions 1.0, 1.1 and 2.0 (well tested, clean implementation) Includes service proxy
• CherryPy (python)
• Zope 2
• Zope 3
• Twisted JSON-RPC - Web, Web2, and TCP

Ruby
