Symfony2: my first service - php

Question

I'm struggling with the error:
The autoloader expected class "ElectricAnimal\CardsinthepostBundle\Services\MyService" to be
defined in file
"/vhosts/domains/cardsinthepost.com/public/app/../src/ElectricAnimal/CardsinthepostBundle/Services/MyService.php".
You probably have a typo in the namespace or the class name.
But that class is defined in exactly that file!
/src/ElectricAnimal/CardsinthepostBundle/Services/MyService.php:
<?php
// Bundle/ElectricAnimalCardsinthepost/Services/MyService.php
namespace Bundle\ElectricAnimalCardsinthepost\Services;
class MyService
{
public function __construct()
{
}
public function sum($n1, $n2) {
return $n1 + $n2;
}
}
In my controller I have:
<?php
class DefaultController extends Controller
{
public function indexAction()
{
$number = $this->get('my_service')->sum(12, 37);
return new Response('<pre>' . $number . '</pre>');
}
}
?>
Additional info:
/src/ElectricAnimal/CardsinthepostBundle/DependencyInjection/ElectricAnimalCardsinthepostExtension.php:
<?php
namespace ElectricAnimal\CardsinthepostBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
/**

* To learn more see {#link http://symfony.com/doc/current/cookbook/bundles/extension.html}
*/
class ElectricAnimalCardsinthepostExtension extends Extension
{
/**
* {#inheritDoc}
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('services.yml');
}
}
/src/ElectricAnimal/CardsinthepostBundle/Resources/config/services.yml:
services:
my_service:
class: ElectricAnimal\CardsinthepostBundle\Services\MyService

Answer 1

My answer:
MyService.php was using slightly the wrong namespace. Needed:
// Bundle/ElectricAnimal/Cardsinthepost/Services/MyService.php
namespace ElectricAnimal\CardsinthepostBundle\Services;
instead of
// Bundle/ElectricAnimalCardsinthepost/Services/MyService.php
namespace Bundle\ElectricAnimalCardsinthepost\Services;
Symfony2 naming drives me round the bend sometimes!
Had already constructed question so hope useful for someone to have this answer.
