Using 3rd-Party Libraries - Paypal php lib


I encountered a problem with using 3rd-Party libraries. I followed the "Home » Documentation » The Definite Guide to Yii » Using 3rd-Party Libraries" tutorial, but with Php Paypal library (for adaptive payments).

The Error 500 is:

YiiBase::include(BaseAddress.php) [<a href=‘function.YiiBase-include’>function.YiiBase-include</a>]: failed to open stream: No such file or directory.

I included in my controller the follow code:



The Paypal folder under vendors folder contains the Paypal library.

Do you have some idea?
