Generating a single Entity from existing database using symfony2 and doctrine

I donno why/how but it works

here's the code :

orm:
    auto_generate_proxy_classes: "%kernel.debug%"
    entity_managers:
        extranet:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            auto_mapping: true
        crawl:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            connection: crawl
            mappings:
                DbBccCrawlBundle: ~

the thing is that I tried that at the start and it failed (the class X not found in...)

If anyone has an explenation, I'll be more than happy to read it.

Thanks anyway

This was the 2nd part of the question, here's the begening : The class 'X' was not found in the chain configured namespaces ... when I try a multiple connection with doctrine

I finally solved the problem but dont know if it is the best way

I override the constructor method in connect method in ConnectionWrapper:

public function connect()
{

    if (!$this->session->has(self::SESSION_ACTIVE_DYNAMIC_CONN)) {
        throw new InvalidArgumentException('You have to inject into valid context first');
    }
    if ($this->isConnected()) {
        return true;
    }

    $driverOptions = isset($params['driverOptions']) ? $params['driverOptions'] : array();

    $params = $this->getParams();
    $realParams = $this->session->get(self::SESSION_ACTIVE_DYNAMIC_CONN);
    $params['dbname'] = $realParams[0];

    //overrride constructor in parent class Connection to set new parameter dbname
    parent::__construct($params, $this->_driver, $this->_config,$this->_eventManager);

    $this->_conn = $this->_driver->connect($params, $params['user'], $params['password'], $driverOptions);


    if ($this->_eventManager->hasListeners(Events::postConnect)) {
        $eventArgs = new ConnectionEventArgs($this);
        $this->_eventManager->dispatchEvent(Events::postConnect, $eventArgs);
    }

    $this->_isConnected = true;

    return true;
}
