XML-RPC Sample with a Java Server and a Python Client

README.md

compile:

mvn clean compile assembly:single

start XML-RPC Server:

java -cp target/xmlrpc-test-server-1.0-jar-with-dependencies.jar net.thomd.JavaServer

monitor any traffic on loopback interface on port 8080:

ngrep -d lo0 port 8080

call method sumAndDifference(11,7):

python -c 'import xmlrpclib; print xmlrpclib.Server("http://localhost:8080/RPC2").sample.sumAndDifference(11,7)'

JavaServer.java

// src/main/java/net/thomd/JavaServer.java

package net.thomd;

import java.util.Hashtable;
import helma.xmlrpc.*;

public class JavaServer {

    public JavaServer () {
        // Our handler is a regular Java object. It can have a
        // constructor and member variables in the ordinary fashion.
        // Public methods will be exposed to XML-RPC clients.
    }

    public Hashtable sumAndDifference (int x, int y) {
        Hashtable result = new Hashtable();
        result.put("sum", new Integer(x + y));
        result.put("difference", new Integer(x - y));
        return result;
    }

            server.addHandler("sample", new JavaServer());

        } catch (Exception exception) {
