Paypal Adaptive Payments SDK integration in Yii 1.1.x

Yii 1.1 Extensions
1

I am trying to integrate Paypal Adaptive Payments SDK in Yii 1.1.x framework.

I installed composer and created a composer.json file with the following contents.


{

    "name": "me/myApp",

    "require": {

        "paypal/adaptivepayments-sdk-php":"3.8.*"

    }

}

and I run composer update. I have updated the Configuration.php. After I require PPBootStrap.php in my application


Yii::import('application.extensions.pp.*', true);

spl_autoload_unregister(array('YiiBase','autoload'));

require_once('PPBootStrap.php');

spl_autoload_register(array('YiiBase','autoload'));

after I create the receiver


$receiver = array();

$receiver[0] = new Receiver();

and I get the error:


include(Receiver.php): failed to open stream: No such file or directory

I integrated Angelleye PayPal library following the same logic with no problems (I am able to make payments). But I want to use the official sdk from PayPal.

I am not sure why the class Receiver is not being loaded. Any information and/or guidance on how to solve this issue will be greatly appreciated.
