problem in setting Restful-Yii

I want to set-up Restful Yii and for that I have referred http://ift.tt/1I9HtWN.

code of siteController
public function accessRules()
        {
        return array(
            array('allow', 'actions'=>array('REST.GET', 'REST.PUT', 'REST.POST', 'REST.DELETE', 'REST.OPTIONS'),
            'users'=>array('*'),
            ),
            array('deny',  // deny all users
                'users'=>array('*'),
            ),
        );
         } 


       public function restEvents() {

        $this->onRest('req.get.abc.render',function(){
          echo "Hi";
        });

main.php
