I\'ve got a dubious issue. I have a set of existing annotated Doctrine entities which have been successfully used in a Symfony2/Doctrine2 project. However, I\'m currently isolat

The accepted answer is ok but the same thing could be achieved in less verbose manner:

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = array( realpath(__DIR__."/../src/My/Entity") );
$isDevMode = TRUE;

// the connection configuration
$dbParams = array(
    'driver'   => 'pdo_mysql',
    'user'     => 'myuser',
    'password' => 's3cr3t',
    'dbname'   => 'mydb',
);

$config = Setup::createAnnotationMetadataConfiguration(
    $paths, $isDevMode, null, null, false
);
$config->setQueryCacheImpl(new \Doctrine\Common\Cache\ArrayCache());
$entityManager = EntityManager::create($dbParams, $config);

//-- This I had to add to support the Mysql enum type.
$platform = $entityManager->getConnection()->getDatabasePlatform();
$platform->registerDoctrineTypeMapping('enum', 'string');

All here is about usage of simple annotation driver or not (last parameter of the Setup::createAnnotationMetadataConfiguration function. By default, a simple annotation driver is used which doesn't recognise the @ORM\Entity annotation.
