Question

Hello everyone so i want to use xmlRpc in my simple project i have downloaded org-apache-xmlrpc.jar

this is part of my code

import java.util.*;

import org.apache.xmlrpc.webserver.WebServer;
import org.apache.xmlrpc.server.*;
public class Serveur{
    
    private static Vector<String> user = new Vector<String>();
    String msg_courant = null;
    
    public static void main (String [] args){
    try { 
            System.out.println("Attempting to start XML-RPC Server...");
            
            WebServer server = new WebServer(9980);
            PropertyHandlerMapping handlerMapping = new PropertyHandlerMapping();
            handlerMapping.addHandler("sample", Serveur.class);
            XmlRpcServer xmlRpcServer = server.getXmlRpcServer();
            xmlRpcServer.setHandlerMapping(handlerMapping);

            XmlRpcServerConfigImpl serverConfig = (XmlRpcServerConfigImpl) xmlRpcServer.getConfig();
            serverConfig.setEnabledForExtensions(true);
            serverConfig.setContentLengthOptional(false);

            server.start();
    }
    catch (Exception exception){ System.err.println("JavaServer: " + exception); }

Answer 1

That is the content of the lib folder of the package I downloaded ( apache-xmlrpc-3.1.2-bin ) from here :

DOMSerializer is part of the second JAR file that is probably missing on your classpath.

Note: javac is not for running the program, it just compiles the source code.

You've been missing ws-commons-util.jar . You can download it from the web. Try here .
