本文介绍了一个使用Java实现的XMLRPC客户端与服务器的简单示例。客户端通过调用远程过程完成基本算术运算，服务器端提供这些算术运算的服务。示例中包含了客户端和服务端的具体代码实现。

简单的 XMLRPC

java---XmlRpcClient

package com.company;

import org.apache.xmlrpc.XmlRpcClient;
import org.apache.xmlrpc.XmlRpcException;

import java.net.MalformedURLException;
import java.util.Hashtable;
import java.util.Vector;

public class Main {

    private final static String server_url = "http://localhost:8080/RPC2";

    public static void main(String[] args) {
	// write your code here
        // Create an object to represent our server.
        XmlRpcClient server = null;
        try {
            server = new XmlRpcClient(server_url);
            // Build our parameter list.
            Vector params = new Vector();
            params.addElement(new Integer(7));
            params.addElement(new Integer(2));
// Call the server, and get our result.
              Hashtable result = (Hashtable) server.execute("cals.sub", params);
              int sum = ((Integer) result.get("sub")).intValue();
// Print out our result.
              System.out.println("Sum: " + Integer.toString(sum));

        } catch (org.apache.xmlrpc.XmlRpcException exception) {
            System.err.println("JavaClient: XML-RPC Fault #" +
                    Integer.toString(exception.code) + ": " + exception.toString());
        } catch (Exception exception) {
            System.err.println("JavaClient: " + exception.toString());
        }

       // } catch (MalformedURLException e) {
       //     e.printStackTrace();
        //}

    }
}

Java xmlRpc-Server

package com.company;
import java.util.Hashtable;

import org.apache.xmlrpc.*;

public class Main {
    public Main(){
      System.out.println("Handler registered as 'cals'");
    }
    public Hashtable add(int x ,int y){
        Hashtable result = new Hashtable();
        result.put("add",new Integer(x+y));
        return  result;
    }

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

    public Hashtable div(int x,int y){
        Hashtable result = new Hashtable();
        if( y == 0){
            result.put("div error ",new Integer(0));
        }else {
            result.put("div ",new Integer(x/y));
        }
        return  result;
    }

    public Hashtable mul(int x,int y){
        Hashtable result = new Hashtable();
        result.put("mul",new Integer(x*y));
        return  result;
    }

    public static void main(String[] args) {
        // write your code here
        try {
            WebServer server = new WebServer(8080);
            server.addHandler("cals", new Main());
            server.start();
        }
        catch(Exception exception){
                System.err.println("JavaServer: " + exception.toString());
            }
        }

}
