"Class XXX is not a valid entity or mapped super class" after moving the class in the filesystem

Had this problem - don't forget the annotation * @ORM\Entity like below:

/** * Powma\ServiceBundle\Entity\User * * @ORM\Entity * @ORM\Table(name="users") */

Had this problem yesterday and found this thread. I created the entity with the mapping in a new bundle (e.g. MyFooBundle/Entity/User.php), did all the configuration according to the docs but got the same error from above when trying to load the app.

In the end I realized that I wasn't loading MyFooBundle in AppKernel:

new My\FooBundle\MyFooBundle()

A great way to debug this is to run this command:

app/console doctrine:mapping:info

Do check your config.yml file, should be containing something like this:

# Doctrine Configurationdoctrine:    dbal:        driver:   %database_driver%        host:     %database_host%        port:     %database_port%        dbname:   %database_name%        user:     %database_user%        password: %database_password%        charset:  UTF8        types:            json: Sonata\Doctrine\Types\JsonType    orm:        auto_generate_proxy_classes: %kernel.debug%        # auto_mapping: true        entity_managers:            default:                mappings:                    FOSUserBundle: ~                    # ApplicationSonataUserBundle: ~                    YourUserBundle: ~                    SonataUserBundle: ~

Add your own bundle to the mappings list.
