Symfony – Error: “No route found for “GET /web/app_dev.php””

I have created a bundle using the command php app/console generate:bundle this add the bundle in /app/AppKernel.php and also in /app/config/routing.yml. If I try to access the URL http://devserver/web/app_dev.php/bank_homepage I got a 404 error. I check /app/logs/prod.log and see this:

[2013-07-29 13:41:27] request.ERROR: Uncaught PHP Exception
Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No
route found for "GET /web/app_dev.php/bank_homepage"" at
/var/www/html/app/cache/prod/classes.php line 1880
{"exception":"[object]
(Symfony\Component\HttpKernel\Exception\NotFoundHttpException: No
route found for \"GET /web/app.php/bank_homepage\" at
/var/www/html/app/cache/prod/classes.php:1880,
Symfony\Component\Routing\Exception\ResourceNotFoundException: at
/var/www/html/app/cache/prod/appProdUrlMatcher.php:1222)"} []

What I'm doing wrong?

This is my /app/config/routing.yml

bank:
    resource: "@BankBundle/Resources/config/routing.yml"
    prefix:   /
....

And this is my /src/BankBundle/Resources/config/routing.yml

bank_homepage:
    pattern:  /hello/{name}
    defaults: { _controller: BankBundle:Default:index }
    requirements:
      _method: GET

EDIT some tests
I change the URL from http://devserver/web/app_dev.php/bank_homepage to http://devserver/web/app_dev.php and then the error changes to this:

[2013-07-29 14:22:15] request.ERROR: Uncaught PHP Exception
Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No
route found for "GET /web/app_dev.php"" at

{"exception":"[object]

Symfony\Component\Routing\Exception\ResourceNotFoundException: at
/var/www/html/app/cache/prod/appProdUrlMatcher.php:1222)"} []

Which practically is the same

PS: I check (this)[No route found for "GET /portfolio but this didn't work for me
