nmote-xr - Simple (X)ML-(R)PC library

Java 1.5+ client and server implementation of XML-RPC protocol. See http://en.wikipedia.org/wiki/XML-RPC

Features

• Supports Java 1.5+
• Reflective and programmable calls
• Basic springframework integration
• No external dependecies other than slf4j-api
• Server and client support
• BSD style license

Building

To produce nmote-xr.jar you will need apache maven installed. Run:

mvn clean package

Usage

• Call userland service

	Endpoint server = XR.client(new URI("http://betty.userland.com/RPC2"));
	MethodCall call = new MethodCall("examples.getStateName", 3);
	MethodResponse response = server.call(call);
	System.out.println(call + " => " + response);

• Same as above, but use type safe interface 'Betty'

	interface Betty {
		@XRMethod("examples.getStateName")
		public String getStateName(int n);
	}

	Betty betty = XR.proxy(new URI("http://betty.userland.com/RPC2"), Betty.class);
	String result = betty.getStateName(41);
	System.out.println(result);

• There is also a com.nmote.xr.Meta interface to support rudimentary reflection of XML-RPC

		Meta xrs = XR.proxy(new URI("http://betty.userland.com/RPC2"), Meta.class);
		System.out.println(xrs.listMethods());

• To expose a simple XML-RPC HTTP server, you don't need no external dependencies

	@XRMethod(value = "example.helloWorld", help = "Returns 'Helo ' + argument")
	public static String hello(Object s) {
		return "Hello '" + s + "'";
	}

	public static void main(String[] args) throws Exception {
		NanoServer server = new NanoServer("http://localhost:7070");
		server.add(XR.server(HelloWorldServer.class));
		server.start();
	}

• For production you will need to expose com.nmote.xr.Endpoint via one or more com.nmote.xr.XRServlet instances. Endpoints are passed in a servlet context. (See the source for more info)

• Package com.nmote.xr.spring has support classes for exposing clients and server using springframework contexts.
