蛋糕从组件调用外壳

如何从我的组件调用 shell。

这是我的外壳

<?php 
   class PrintShell extends AppShell {
    function main()
    {
        App::import(‘Component’, ‘BusinessLogic’);
        $businessLogic = & new BusinessLogicComponent();
        $businessLogic->initialize();
        $settings = $businessLogic->senReminderEmail();
        // senReminderEmail Mail function is defined in my Controller/Components/BusinessLogicComponent.php File
    }
}
?>

我不希望它使用命令调用。我该怎么做。任何帮助这有意义吗？
