Doctrine 2 Entity Error - php

Question

I would like to ask, if anybody obtained such error before. Since I am stuck for 2 hours fixing bugs with doctrine already. So any kind of of help would be appreciate.
To the point. I am fighting with doctrine Entity Manager I can't make it work.
I created entity and doctrine class to work with, but I am getting an error all the time:
Fatal error: Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "MSP\Model\Entity\Category" is not a valid entity or mapped super class.' in /home/dariss/www/dom/php/MenuSiteProject/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:216 Stack trace: #0 /home/dariss/www/dom/php/MenuSiteProject/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/Driver/AnnotationDriver.php(87): Doctrine\ORM\Mapping\MappingException::classIsNotAValidEntityOrMappedSuperClass('MSP\Model\Entit...') #1 /home/dariss/www/dom/php/MenuSiteProject/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(113): Doctrine\ORM\Mapping\Driver\AnnotationDriver->loadMetadataForClass('MSP\Model\Entit...', Object(Doctrine\ORM\Mapping\ClassMetadata)) #2 /home/dariss/www/dom/php/MenuSiteProject/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(318): Doctrine\ORM\Mapping\ClassMetadataFactory->doLoadMetadata(Object(Doctrine\ORM\Mapping\ClassMetadata), NULL, false, Array) in /home/dariss/www/dom/php/MenuSiteProject/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php on line 216
My entity class.
namespace MSP\Model\Entity;
use Doctrine\ORM\Mapping as ORM;
/**

/**

*/
private $id;
/**

*/
private $name;
/**

*/
private $parent;
/**

*/
public function getId()
{
return $this->id;
}
/**

public function setName($name)
{
$this->name = $name;
return $this;
}
/**

public function getName()
{
return $this->name;
}
/**

public function setParent($parent)
{
$this->parent = $parent;
return $this;
}
/**
* #return int
*/
public function getParent()
{
return $this->parent;
}
Doctrine class:
namespace MSP\Helper;
use Doctrine\Common\ClassLoader,
Doctrine\ORM\Configuration,
Doctrine\ORM\EntityManager,
Doctrine\Common\Cache\ArrayCache,
Doctrine\DBAL\Logging\EchoSQLLogger;
class Doctrine{
public $em = null;
public function __construct()
{
require_once __DIR__.'/../../../vendor/doctrine/common/lib/Doctrine/Common/ClassLoader.php';
$doctrineClassLoader = new ClassLoader('Doctrine', '/');
$doctrineClassLoader->register();
$entitiesClassLoader = new ClassLoader('MSP\Model\Entity', '/../Model/Entity');
$entitiesClassLoader->register();
$proxiesClassLoader = new ClassLoader('Proxies', '/../Proxies/');
$proxiesClassLoader->register();
// Set up caches
$config = new Configuration;
$cache = new ArrayCache;
$config->setMetadataCacheImpl($cache);
$driverImpl = $config->newDefaultAnnotationDriver(array('/../Model/Entity'), true);
$config->setMetadataDriverImpl($driverImpl);
$config->setQueryCacheImpl($cache);
$config->setQueryCacheImpl($cache);
// Proxy configuration
$config->setProxyDir('/proxies');
$config->setProxyNamespace('Proxies');
// Set up logger
$logger = new EchoSQLLogger;
//$config->setSQLLogger($logger);
$config->setAutoGenerateProxyClasses( TRUE );
$iniParser = new \MSP\Helper\IniParser();
$configuration = $iniParser->getConfig();
// Database connection information
$connectionOptions = array(
'driver' => $configuration['driver'],
'user' => $configuration['username'],
'password' => $configuration['password'],
'dbname' => $configuration['dbname'],
'host' => $configuration['host']
);
// Create EntityManager
$this->em = EntityManager::create($connectionOptions, $config);
}
}
Test file:
$doctrine = new MSP\Helper\Doctrine();
$doctrine->em->find('MSP\Model\Entity\Category', 1);

Answer 1

You need to drop the #ORM prefixes when you annotate the entities.
But I followed the example in the Symfony 2 documentation? Yep. For Symfony 2 you need to use #ORM. But your test cases uses "pure" doctrine which means no #ORM.
If you really need to run your stuff using pure doctrine then consider using yaml notation.
Why does S2 use #ORM? It's a long sad story but basically it introduced the #ORM prefix so other annotations would not clash with Doctrine.
Can you tweak the Doctrine configuration to allow the user of #ORM? Yep. But I forget how. You can search for it.
Bottom line: Consider just using the Symfony 2 Doctrine service. It's easier.

Answer 2

You set an absolute path /../Model/Entity.
You need to set ./../Model/Entity
