Problem with basic authentication using XML-RPC

[IBWT]

Hello.

I downloaded the examples zip from the XML-RPC Trac plugin site and I
am trying to access my Trac repository using XML-RPC. This is my code:

package es.modelum.migration.mylyn.trac;

import java.net.MalformedURLException;
import java.net.URL;

import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;
import org.lustin.trac.xmlprc.Ticket;
import org.lustin.trac.xmlprc.TrackerDynamicProxy;

import tasks.Task;

public class TracInitializer {
XmlRpcClient rpcClient = new XmlRpcClient();
TrackerDynamicProxy rpcProxy;

public TracInitializer(String serverURL, String username,
String
password) throws MalformedURLException {
XmlRpcClientConfigImpl rpcConf = new
XmlRpcClientConfigImpl();
rpcConf.setBasicUserName(username);
rpcConf.setBasicPassword(password);
rpcConf.setServerURL(new URL(serverURL));

rpcClient.setConfig(rpcConf);
rpcProxy = new TrackerDynamicProxy(rpcClient);
}

public void getTicket(int ticketID) {
Ticket ticket =
(Ticket)rpcProxy.newInstance(Ticket.class);
System.err.println(ticket.getTicketFields());
}

public void createTicket(Task task) {

}

static public void main(String[] args) {
try {
TracInitializer tracInitializer = new
TracInitializer("http://modelum.es/trac/mylyntest", "user", "pass");
tracInitializer.getTicket(2);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

When the request ticket.getTicketFields() is called, I get the
following exception:

Exception in thread "main"
java.lang.reflect.UndeclaredThrowableException

$1.invoke(TrackerDynamicProxy.java:125)

User and password are correct and the Trac serves XML-RPC requests
correctly from the Mylyn Trac connector.

What am I doing wrong?

Your URL seems bad. It gets a 401 (not authorized), and I then doubt
that that URL challenges for authentication - and even if it does it
still lacks a call to the actual RPC handler. The URL should look
something like this (assuming "mylyntest" is a your project):

http://modelum.es/trac/mylyntest/login/rpc

Hello Simon thanks for your response.

My URL works properly with the Ruby XML-RPC implementation (trac4r).
The URL you provide is not recognized by the server, an exception is
thrown by the client saying that no input stream can be created.
