Errors Integrating Doctrine Into Zend Framework

When trying to run a simple command $msg = $this->_em->find("Entities\Message", 1); in my IndexController I get the following errors:

( ! ) Warning: class_parents() [function.class-parents]: Class Entities\Message does not exist and could not be loaded in C:\wamp\www\KosherOven\library\Doctrine\ORM\Mapping\ClassMetadataFactory.php on line 222

Here is my doctrine bootstrap code:

protected function _initDoctrine()
{
    /* Autoload classes */
    require_once 'Doctrine/Common/ClassLoader.php';
    $classLoader = new Doctrine\Common\ClassLoader('Doctrine');
    $classLoader->register();
    // load the doctrine class loader for Symfony library components
    $classLoader = new \Doctrine\Common\ClassLoader('Symfony', 'Doctrine');
    $classLoader->register();
    $classLoader = new \Doctrine\Common\ClassLoader('Entities', APPLICATION_PATH . '/models');
    $classLoader->register();

    /* Choose cache */

    if (APPLICATION_ENV == "development") {
        $cache = new \Doctrine\Common\Cache\ArrayCache;
    } else {
        //$cache = new \Doctrine\Common\Cache\ApcCache;
        $cache = new \Doctrine\Common\Cache\ArrayCache;
    }

    $config = new \Doctrine\ORM\Configuration;
    $config->setMetadataCacheImpl($cache);

    $driverImpl = $config->newDefaultAnnotationDriver(APPLICATION_PATH . '/configs/doctrine/Mapping');
    $config->setMetadataDriverImpl($driverImpl);
    $config->setQueryCacheImpl($cache);
    $config->setProxyDir(APPLICATION_PATH . '/Proxies');
    $config->setProxyNamespace('Proxies');

    if (APPLICATION_ENV == "development") {
        $config->setAutoGenerateProxyClasses(true);
    } else {
        $config->setAutoGenerateProxyClasses(false);
    }

    $configObj = $this->_initConfig();

    $connectionOptions = array(
        'driver'   => $configObj->database->adapter,
        'dbname'   => $configObj->database->params->dbname,
        'host'     => $configObj->database->params->host,
        'user'     => $configObj->database->params->username,
        'password' => $configObj->database->params->password
    );
    $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);

    Zend_Registry::set('em', $em);
}

I am using Doctrine 2.0.4.

I can't think of any other info to provide, but I would be happy to add more information if needed.

Make sure you have the following class in application/models/Entities/Message.php

namespace Entities;

/**
 * @Entity
 */
class Message
{
    // ...

Also, I'm not sure about this line

// load the doctrine class loader for Symfony library components
$classLoader = new \Doctrine\Common\ClassLoader('Symfony', 'Doctrine');

Isn't that saying the Symfony namespace / folder is in the Doctrine directory?

Edit: My guess would be it should look like this

$classLoader = new \Doctrine\Common\ClassLoader('Symfony');

UPDATE

I think I see what's missing. You aren't telling the annotation driver where to find your entities.

I think this line

$driverImpl = $config->newDefaultAnnotationDriver(APPLICATION_PATH . '/configs/doctrine/Mapping');

should be

$driverImpl = $config->newDefaultAnnotationDriver(APPLICATION_PATH . '/models/Entities');

See http://www.doctrine-project.org/docs/orm/2.0/en/reference/configuration.html

I highly recommend you check out the Bisna integration from Guilherme Blanco - https://github.com/guilhermeblanco/ZendFramework1-Doctrine2

I also have a sort of ZF/Doctrine2 app skeleton here that you're welcome to look at - https://github.com/philBrown/ZFDoctrineSkeleton

Looks like you're not pushing your Doctrine, Symfony, and Entities class loaders onto the Zend autoloader:

require_once 'Doctrine/Common/ClassLoader.php';
$autoloader = \Zend_Loader_Autoloader::getInstance();

$symfonyAutoloader = new \Doctrine\Common\ClassLoader('Symfony');
$autoloader->pushAutoloader(array($symfonyAutoloader, 'loadClass'), 'Symfony');

$doctrineAutoloader = new \Doctrine\Common\ClassLoader('Doctrine');
$autoloader->pushAutoloader(array($doctrineAutoloader, 'loadClass'), 'Doctrine');

$entityAutoloader = new \Doctrine\Common\ClassLoader('Entities', APPLICATION_PATH . '/models');
$autoloader->pushAutoloader(array($entityAutoloader, 'loadClass'), 'Entities');
