access entityManager in XML RPC web API - zend-framework2

Question

Hello Stackoverflow Community.
I am currently developing a XML-RPc Server with Zend Framework 2.
I have a ServiceController which is responsible for creating the Server
class ServiceController extends AbstractActionController{
public function xmlAction()
{
$this->handleXML();
$response = $this->getResponse();
return $response;
}
private function handleXML()
{
$xmlServer = new Zend\XmlRpc\Server();
$xmlServer->setClass('Beam\Model\service\Service', 'service');
echo $xmlServer->handle();
}
}
The ServiceClass is my Webapi
class Service{
/**
* getAvailablePackages
*
* getAvailablePackages is responsible for returning all packages which reference a given licensenumber
*
* #param string $licenseNumber
* #return String
*/
public function getAvailablePackages($licenseNumber){
//need to access the entityManager
$em = $this->getServiceLocator->get('Doctrine\ORM\EntityManager');
return "testresponse";
}
}
The XML RPC server works fine. I can call the getAvailablePackages method with a client and i get "testrespons" as a response.
However the problem is, that i would like to select some data from my database in the getAvailablePackages but i'm not sure how to access the entityManager in a non Controller class.
Does anyone have an idea on how to solve this problem ? Thankx for your responses.

Possible solution would be to have a factory.
<?php
namespace ....;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\ServiceManager\FactoryInterface;
class ServiceFactory implements FactoryInterface
{
public function createService (ServiceLocatorInterface $serviceLocator)
{
return new Service ($serviceLocator->get ('Doctrine\ORM\EntityManager'));
}
}
thus, you would be able to have an access to Entity manager.
