Hey Monks,

I have been sweating over this issue for 2 days: For some reason when I use credentials in the following way, the debug states the agent is unauthorized for use even after I set up the credentials as per instructions:

#!/usr/bin/perl
use warnings;
use strict;
use LWP::Debug qw( + );
use WWW::Mechanize;
use CGI;
use MIME::Base64;
use HTTP::Cookies;

my $netloc = "10.4.4.4:8080";
my $url = "http://" . $netloc . "/admin";
my $realm = "Realm";
my $username = "user";
my $password = "pass";

my $cookie_jar = HTTP::Cookies->new(
    file => 'cookies.dat',
    autosave => 1,
);
my $agent = WWW::Mechanize->new(
    autocheck => 1,
    quiet => 0,
    agent_alias => 'Mac Mozilla',
    cookie_jar => $cookie_jar,
);

# Supply the necessary credentials
$agent->credentials($netloc, $realm, $username, $password);
$agent->get($url);

# Throw error if page not found
$agent->success() or die "Can't fetch the Requested page";
[download]

The output is as follows:

LWP::UserAgent::new: ()
LWP::UserAgent::request: ()

Then I add in the basic authentication information via MIME::Base64::encode AND tack that info to the $agent->get() call as follows AND IT WORKED!

#!/usr/bin/perl
use warnings;
use strict;
use LWP::Debug qw( + );
use WWW::Mechanize;
use CGI;
use MIME::Base64;
use HTTP::Cookies;

my $netloc = "10.4.4.4:8080";
my $url = "http://" . $netloc . "/admin";
my $realm = "Realm";
my $username = "user";
my $password = "pass";
my @args = (
        Authorization => "Basic " .
            MIME::Base64::encode( $username . ':' . $password )
);

my $cookie_jar = HTTP::Cookies->new(
    file => 'cookies.dat',
    autosave => 1,
);
my $agent = WWW::Mechanize->new(
    autocheck => 1,
    quiet => 0,
    agent_alias => 'Mac Mozilla',
    cookie_jar => $cookie_jar,
);

# Supply the necessary credentials
$agent->credentials($netloc, $realm, $username, $password);
$agent->get($url,@args);


# Throw error if page not found
$agent->success() or die "Can't fetch the Requested page";

Output:

Is there something I am doing wrong in the first code example? The web server I am going against is JBOSS v4.2.2.
Thank you for your input. /rob
