[2.1] Problem with webservices

[Mariano C.]

I'm try to develop a simple webservices in CakePHP 2.1. So, i first created 
a DB table:

    CREATE TABLE IF NOT EXISTS `people` (
>       `id` char(36) COLLATE utf8_bin NOT NULL,
>       `first_name` varchar(100) COLLATE utf8_bin DEFAULT NULL,
>       `last_name` varchar(100) COLLATE utf8_bin NOT NULL,
>       `home_address` varchar(100) COLLATE utf8_bin DEFAULT NULL,
>       `job_address` varchar(100) COLLATE utf8_bin DEFAULT NULL,
>       `phone` varchar(20) COLLATE utf8_bin DEFAULT NULL,
>       `fax` varchar(20) COLLATE utf8_bin DEFAULT NULL,
>       `mail` varchar(100) COLLATE utf8_bin DEFAULT NULL,
>       `birth_date` int(11) DEFAULT NULL
>     ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin 


Than I've created a simple Person model:

    <?php
>     class Person extends AppModel {
>         public $name = 'Person';
>     }


And respective controller:

    <?php
>     class PeopleController extends AppController {
>         public $components = array('RequestHandler');
>     
>         public function index() {      
>             $people = $this->Person->find('all');
>             $this->set(array(
>                 'people' => $people,
>                 '_serialize' => array('person')
>             ));
>         }
>     }


and finally, in routes.php, I've mapped the proper roote:

    <?php
>     Router::mapResources('people');
>     Router::parseExtensions('json');
>     Router::connect('/', array('controller' => 'pages', 'action' => 
> 'display', 'home'));
>     Router::connect('/pages/*', array('controller' => 'pages', 'action' => 
> 'display'));
>     CakePlugin::routes();
>     require CAKE . 'Config' . DS . 'routes.php';


but when I try to reach ht_tp://localhost/cakephp/people.json I get:

    <pre class="cake-error"><a href="javascript:void(0);"
