[TYPO3-english] Extbase 1.2.0 dispatch problem

[Rayuth You (Yuth)]

Hi list,

In extbase 1.3.0
$bootstrap = t3lib_div::makeInstance('Tx_Extbase_Core_Bootstrap');
$bootstrap->run('', $configuration);

And in 1.2.0, I changed from Tx_Extbase_Core_Bootstrap to 
Tx_Extbase_Dispatcher
$bootstrap = t3lib_div::makeInstance('Tx_Extbase_Dispatcher');
$bootstrap->dispatch('', $configuration);

But I got message error:
Fatal error: Class 'Tx_ExtName_Controller_StandardController' not found 
in /var/www/typo3_src-4.5.0/t3lib/class.t3lib_div.php on line 5277

My configuration:
$configuration = array(
	'pluginName' => 'Pi1',
	'extensionName' => 'ExtName',
	'switchableControllerActions' =>  array(
		'ControllerName' => array(
			'actions' => 'actionName'
		)
	)
);

Did I use the wrong class name? or wrong configuration? Any hint?

Regards,
Yuth
