Sample code needed for XMLRPC 3.0

[Vrihad Shoonya <vr...@gmail.com>]

Dear pals,

Please provide the URL containing the tutorial for using XMLRPC 3.0. I have
searched the Net and found none for the version 3.0 so far. I have tried to
build a sample server and client but it throws XmlRpcException saying that
no handler exists. Following is the server code:

<code>
import org.apache.xmlrpc.webserver.WebServer;
import org.apache.xmlrpc.server.*;
import java.util.*;

public class Trade {
    Tread t;

    private final int port = 8200;
    private final String propertyFile = "server.properties";


    public static void main(String args[]) throws ClassNotFoundException {
        //System.out.println("testing ");
        try {
            Trade t = new Trade();
        } catch (java.io.IOException e) {
            System.out.println("Caught IOException\n");
            e.printStackTrace();
        } catch (org.apache.xmlrpc.XmlRpcException e) {
            System.out.println("Caught IOException\n");
            e.printStackTrace();
        }
    }

    public Trade() throws java.io.IOException,
org.apache.xmlrpc.XmlRpcException, ClassNotFoundException {
        PropertyHandlerMapping mapping = new PropertyHandlerMapping();
        ClassLoader cl = Thread.currentThread().getContextClassLoader();
        mapping.load(cl, propertyFile);
        mapping.addHandler("calculate", Class.forName("Trade"));
        WebServer ws = new WebServer(port);
        XmlRpcServerConfigImpl config = new XmlRpcServerConfigImpl();
        XmlRpcServer server = ws.getXmlRpcServer();
        server.setConfig(config);
        server.setHandlerMapping(mapping);
        ws.start();
    }

    public String calculate(String n1, String n2){
        int ans = Integer.parseInt(n1)+Integer.parseInt(n2);
        return String.valueOf(ans);
    }
}
</code>

Empty file server.properties exists in the classpath.

Following is the client code:

<code>
import org.apache.xmlrpc.client.*;
import org.apache.commons.httpclient.*;
import org.apache.xmlrpc.XmlRpcException;
import java.util.*;
import java.net.*;

//import org.apache.xmlrpc.webserver.WebServer;

public class TradeClient {

    public static void main(String args[]) {
            TradeClient t = new TradeClient();
    }

    public TradeClient() {
        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
        try {
            config.setServerURL(new URL("http://127.0.0.1:8200/"));
        } catch (java.net.MalformedURLException e) {
            System.out.println("Caught MalformedURLException\n");
            e.printStackTrace();
        }
        try {
            XmlRpcClient client = new XmlRpcClient();
            client.setTransportFactory(new
XmlRpcCommonsTransportFactory(client));
            client.setConfig(config);
            Object[] params = new Object[]{new Integer(33), new Integer(9)};
            Integer result = (Integer) client.execute("calculate", params);
        } catch (XmlRpcException e) {
            System.out.println("Caught XmlRpcException\n");
            e.printStackTrace();
        }
    }
}
</code>

If tutorial is not available for version 3.0 of XMLRPC, then post your
own sample
code for working client and server parts which can be studied by others.

Thanks in advance.
