xmlrpc response error

[eluser]veledrom[/eluser]
Hi,

I am not sure if there is something wrong here or not since I receive what I want but why do I also get the error message at end of server response? Error: The XML data received was either invalid or not in the correct form for XML-RPC. Turn on debugging to examine the XML data further.

Thanks in advance.

Client:

Code:

class Client extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        
        $this->load->helper('url');
        $this->load->library('xmlrpc');
    }
    
    public function index()
    {
        $data['title'] = 'xmlrpc';
        $data['heading'] = 'Welcome to xmlrpc client';
        
        $this->load->view('client_view.php', $data);
    }
    
    public function request()
    {
        $this->xmlrpc->set_debug(TRUE);
        
        $server_url = site_url('server');

        $this->xmlrpc->server($server_url, 80);
        $this->xmlrpc->method('login');
        
        $request = array(
                                array(
                                    array('request' => 'login'),
                                    'struct'),
                                array(
                                    array('username' => 'meme',
                                          'password' => '1234'),
                                    'struct')
                                );
        
        $this->xmlrpc->request($request);
        
        if(! $this->xmlrpc->send_request())
        {
            echo $this->xmlrpc->display_error();
        }
        else
        {
            echo '<pre>';
            print_r($this->xmlrpc->display_response());
            echo '</pre>';
        }
    }
}

SERVER:

Code:

class Server extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        
        $this->load->library('xmlrpc');
        $this->load->library('xmlrpcs');
    }
    
    function index()
    {
        $config['functions']['login'] = array('function' => 'server.login');
        $config['functions']['add'] = array('function' => 'server.add');
        $config['functions']['search'] = array('function' => 'server.search');
        $config['functions']['list'] = array('function' => 'server.list');

        $this->xmlrpcs->initialize($config);
        $this->xmlrpcs->serve();
    }


    function login($request)
    {
        $username = 'meme';
        $password = '1234';
        
        $parameters = $request->output_parameters();
        
        //echo '<pre>'; print_r($parameters); echo '</pre>'; exit;
        
        if($parameters['1']['username'] == $username && $parameters['1']['password'] == $password)
        {
            $response = 'Successful';
        }
        else
        {
            $response = 'Fail';
        }

        $response = array(
                        array('client requests' => $parameters['0'],
                              'server responds' => $response),
                              'struct');

        return $this->xmlrpc->send_response($response);
    }
}
