[EXTENSION] fullcalendar and MySql

Hi evryone.

My problem is "How to get Callendar Events from MySql DB ?"

I used "events (as a json feed)" but i do not know where to put the "jsonfeed.php" file.

It seems to be in the WebRoot/application root. But I cannot access to protected root from WebRoot/application.

Please, I am waiting for your help and suggestions.
