If you have classABC.php in your includes/classes directory and you try to get autoloader to wake up object CBA in Observer directory in file objCBA.php with following beginning;

require_once(DIR_WS_CLASSES . 'class.ABC.php');
$CBA = new ABC ();

What is the right way to use autoloaders if this class is going to work with shopping cart for example?

Is this even close?

$autoLoadConfig[90][] = array('autoType'=>'classInstantiate',
'loadFile'=>'observers/obj.CBA.php');

$autoLoadConfig[90][] = array('autoType'=>'classInstantiate',
'className'=>'ABC',
'objectName'=>'CBA');

Thanks for reply,
