ZendFramework入門時異常

ZendFramework入門時錯誤
不知道有沒有人看過PHPWEB2.0開發實戰？這本書裡面的代碼在我的windows系統裡面總是出錯
代碼是這裡
require_once "Zend/Loader.php";
Zend_Loader::registerAutoload();

$config=new Zend_Config_Ini('../settings.ini','development');
Zend_Registry::set('config',$config);

//connect to the database
$params=array('host'=>$config->database->hostname,
'username' =>$config->database->username,
'password'=>$config->database->password,
'dbname'=>$config->database->database);

$db=Zend_Db::factory($config->database->type,$params);
Zend_Registry::set('db','$db');
$db->query('select 1');

//handle the user requerst
$controller=Zend_Controller_Front::getInstance();
$controller->setControllerDirectory($config->paths->base."/include/Controllers");
$controller->dispatch(null,null);
?>

錯誤提示是 這裡：

Fatal error: Uncaught exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller specified (error)' in D:\PHPnow-1.5.4\include\Zend\Controller\Dispatcher\Standard.php:194 Stack trace: #0 D:\PHPnow-1.5.4\include\Zend\Controller\Front.php(920): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #1 D:\PHPnow-1.5.4\htdocs\index.php(24): Zend_Controller_Front->dispatch(NULL, NULL) #2 {main} thrown in D:\PHPnow-1.5.4\include\Zend\Controller\Dispatcher\Standard.php on line 194


我看了下出錯代碼的 位置就是那個194行，寫的是：
throw new Zend_Controller_Dispatcher_Exception('Invalid controller specified (' . $request->getControllerName() . ')');


剛剛接觸ZEND FRAMEWORK有點不明白，希望牛人能解開我的這個難題。。。。
