loadClass is not working on server

hi
had a problem with load class in server which worked fine in my local server

if (!$this->modx->loadClass(’request.mgrRequestController’,$this->config[’model_path’],true,true)) {
return ’Could not load request handler.’;
}
worked fine in my local server
but on main server the class is not loading
if i use require once its working fine like
[require_once($this->config[’model_path’].’request/mgrRequestController.class.php’);
$this->request = new mgrRequestController($this);

why it was happening like that

will the load class depends on server environment or...

how can i fix this

some help is appricated

thanks

Try renaming the file all lowercase. The loadClass method lowercases the class names before it looks for them on the filesystem.
I’m guessing that a mixed-case class filename would work on Windows, but not elsewhere.

thx netprophet
yes the problem is with mixed case naming of file

now its fixed

thanks for your help
