Basic Authentication with xmlrpc-3.1

[Simson Garfinkel]

Greetings. I've spent about 20 hours trying to get basic authentication (username & password) to work with xmlrpc-3.1. No luck. My demo program works with no username & password (if authentication on the server is disabled) but fails with a 401 error if authentication is enabled.

Here is my test program:

This has been very frustrating. I've scanned the Internet, Google, and this website, but I can't find any successful examples of Basic Authentication being used with xmlrpc. (I did find some email messages saying it was broken in the 2.0 release.) Any help that you could give me would be greatly appreciated. Honestly, I think that there needs to be example code included in the release that shows this... /* From http://wiki.rpath.com/wiki/rPath_Appliance_Platform_Agent:XML-RPC_Java_Client */

import java.net.URL;
import java.util.HashMap;

import org.apache.xmlrpc.client.*;


public class Test4 {

    }

    public static void main(String[] args) throws Exception {

        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
        config.setServerURL(new URL("http://example.org/query.cgi";));
        config.setBasicUserName("username");
        config.setBasicPassword("password");
        XmlRpcClient client = new XmlRpcClient();
        client.setConfig(config);

        Object[] ag = new Object[1];
        ag[0] = "0093J1AK132486";


        System.out.println("Returned: " + result);
        System.out.println("Finished.");
    }
}


And here are the stack trace:
