Module Magento Fatal error: Class 'Mage_Cashondelivery_Helper_Data' ne trouve pas dans \xampp\htdocs\magento\app\Mage.php sur la ligne de 516

Je suis en train d'élaborer un Module de paiement pour Magento. Je l'ai fait à l'aide de ce tutoriel

http://www.magentocommerce.com/wiki/5_-_modules_and_development/payment/create-payment-method-module

J'ai créé un dossier

app/local/Companyname/Cashondelivery/Block
app/local/Companyname/Cashondelivery/Model
app/local/Companyname/Cashondelivery/controller
app/local/Companyname/Cashondelivery/etc
app/local/Companyname/Cashondelivery/helpers

Puis j'ai créé un modèle de classe

<?php 
/**
* Our test CC module adapter
*/
class Companyname_Cashondelivery_Model_createorder extends Mage_Payment_Model_Method_Cc
{
/**
* unique internal payment method identifier
*
* @var string [a-z0-9_]
*/
protected $_code = 'newmodule';
/**
* Here are examples of flags that will determine functionality availability
* of this module to be used by frontend and backend.
*
* @see all flags and their defaults in Mage_Payment_Model_Method_Abstract
*
* It is possible to have a custom dynamic logic by overloading
* public function can* for each flag respectively
*/
/**
* Is this payment method a gateway (online auth/charge) ?
*/
protected $_isGateway               = true;
/**
* Can authorize online?
*/
protected $_canAuthorize            = true;
/**
* Can capture funds online?
*/
protected $_canCapture              = false;
/**
* Can capture partial amounts online?
*/
protected $_canCapturePartial       = false;
/**
* Can refund online?
*/
protected $_canRefund               = false;
/**
* Can void transactions online?
*/
protected $_canVoid                 = true;
/**
* Can use this payment method in administration panel?
*/
protected $_canUseInternal          = true;
/**
* Can show this payment method as an option on checkout payment page?
*/
protected $_canUseCheckout          = true;
/**
* Is this payment method suitable for multi-shipping checkout?
*/
protected $_canUseForMultishipping  = true;
/**
* Can save credit card information for future processing?
*/
protected $_canSaveCc = false;
/**
* Here you will need to implement authorize, capture and void public methods
*
* @see examples of transaction specific public methods such as
* authorize, capture and void in Mage_Paygate_Model_Authorizenet
*/        
}
?>

J'ai même créé un fichier dans app/local/Companyname/Cashondelivery/Helper/Data.php

<?php
class Companyname_Cashondelivery_Helper_Data extends Mage_Core_Helper_Abstract
{
}
?>

Mais j'obtiens une erreur lors de l'ouverture de Configuration>Méthodes de Paiement

Fatal error: Class 'Mage_Cashondelivery_Helper_Data' ne trouve pas dans C:\xampp\htdocs\magento\app\Mage.php sur la ligne de 516

Est-il nécessaire d'avoir une classe d'assistance. Je n'ai aucune idée sur les aides et Data.php
