hi,

I'm developing a server in XML-RPC using Java , but when i compile it , i get this error

ServeurSomDiff.java:33: cannot find symbol
symbol  : method addHandler(java.lang.String,java.lang.String)
location: class org.apache.xmlrpc.webserver.WebServer
                server.addHandler("SOMDIFF",new ServeurSomDiff ());

here 's my server :

import java.util.Hashtable;
import org.apache.xmlrpc.webserver.*;
public class ServeurSomDiff {
public ServeurSomDiff (){ 
}
    public Hashtable sumAndDifference (int x, int y) {
        Hashtable result = new Hashtable();
        result.put("somme", new Integer(x + y));
        result.put("difference", new Integer(x - y));
        return result;
      }
      public static void main (String [] args) {
        try {
                   WebServer server = new WebServer(8000);
           server.addHandler("SOMDIFF",new ServeurSomDiff()); 
   server.start(); 
   System.out.println("Serveur lance sur http://localhost:8000/RPC2");  
       } catch (Exception exception) 
       {System.err.println("JavaServer: " + exception.toString());
             }
           }
        }

any ideas on how to fix this . thanks
