title: cant run the controller with symfony 2
body: <p>I generated my bundle with netbeans with no error , then went to my main config file in the app directory and set this:</p>
  
  <pre><code>first_app:
  resource: "@FirstAppBundle/Resources/config/routing.yml"
  prefix:   /
  </code></pre>
  
  <p>Then set this in my bundle routing.yml file:</p>
  
  <pre><code>first_app_homepage:
  pattern:  /hello/{name}
  defaults: { _controller: FirstAppBundle:Hello:index }
  </code></pre>
  
  <p>I have got this controller:</p>
  
  <pre><code>namespace DimaVendor\MytestsBundle\Controller;
  
  use Symfony\Bundle\FrameworkBundle\Controller\Controller;
  use Symfony\Component\HttpFoundation\Response;
  
  class HelloController extends Controller {
  
      public function indexAction($name) {
          return new Response('&lt;html&gt;&lt;body&gt;' . $name . '&lt;/body&gt;&lt;/html&gt;');
      }
  
  
  
  }
  </code></pre>
  
  <p>I get 404 when I go to there:</p>
  
  <pre><code>http://localhost/app.php/hello/Ryan
  </code></pre>
  
  <p>why?</p>
  
  <p>I also cleaned my cache and found no error</p>
