Doctrine ORM Annotations not read - SimpleAnnotationsReader - symfony

Question

I want to be able to use my database just like described in this tutorial:
http://symfony.com/doc/current/book/doctrine.html
Unfortunately, the annotations that were generated through the command
$ php app/console doctrine:generate:entity
are not read as annotations.
php app/console doctrine:schema:update -f
returns
No Metadata Classes to process.
The file looks like this:
<?php
namespace ResBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Page
*
* #ORM\Table()
* #ORM\Entity
*/
class Page
{
... class here with #ORM\ annotations
I think I have found out that this might be because doctrine uses the SimpleAnnotationsReader which only parses annotations like #Column and not #ORM\Column.
The ORM part of my config.yml
orm:
auto_generate_proxy_classes: "%kernel.debug%"
entity_managers:
default:
auto_mapping: true
naming_strategy: doctrine.orm.naming_strategy.underscore
mappings:
ResBundle:
type: annotation
is_bundle: false
dir: %kernel.root_dir%/../src/ResBundle/Entity/
prefix: Resbundle\Entity
alias: ResBundle
The problem is that I have no clue how to switch to the normal AnnotationsReader, answers to other similar questions could not enlighten me.
Is there a setting in my config.yml that need to change? What can I do?

Answer 1

First, check that your bundle is activated.
Second, if you're using bundles, there should be no reason for all that complicated stuff in your config. Why don't you just use the default Doctrine ORM configuration?
doctrine:
orm:
auto_generate_proxy_classes: "%kernel.debug%"
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
That should do the job, given your bundle is properly registered and activated.
