Basic Authentication with xmlrpc-3.1
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.
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...
Here is my test program:
/* 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 call(String url, String user, String pass)
throws Exception {
}
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";
Integer result = (Integer) client.execute(config,"query_sn",
ag);
System.out.println("Returned: " + result);
System.out.println("Finished.");
}
}
And here are the stack trace:

You are right. It works just fine. I coded up an example in python
and found my problem.
I still think that it would be useful to have an example added to the
documentation, however.
Also, the python implementation allows specifying a username &
password in the URL, a practice which is available in both browsers
and specified in RFC 1738 (December 1994). If this class is going to
receive further development, that would be a useful feature.

Unlikely. I am myself using it in more than one project and it is
checked in the test suite.

Hi, Jochen. Thanks for responding to my questions.
I have no problem with the username & password using either my browser
or using my XML-RPC implementation in python. Is there any chance that
this code just doesn't work?

Assuming that you picked the right user name and password, my guess is
that the problem is more likely on the server side?
