En el boostrap tengo:
Código PHP:
   class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initAutoload()
    {
       $autoloader = new Zend_Application_Module_Autoloader(array(
                'namespace' => 'My_',
                    'basePath'  => APPLICATION_PATH . '/library/My_',
                'resourceTypes' => array(
                        'forms'=>array('path'=>'Plugins_/',
                    'namespace'=>'My_Plugins/')
                )
            )
        );
         var_dump(APPLICATION_PATH);
    }
 
} 
    
Código:
  
y en el index esta:[production] phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH "/../library" bootstrap.path = APPLICATION_PATH "/Bootstrap.php" bootstrap.class = "Bootstrap" appnamespace = "Application" resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers" resources.frontController.params.displayExceptions = 0 resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts/" autoloaderNamespaces[] = "Mis_" resources.frontController.plugins.Primero = "My_Plugins_Primero"
Código PHP:
   // Define path to application directory
defined('APPLICATION_PATH')
    || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));
 
// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));
 
 
 
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . '/../library'),
    get_include_path(),
)));
 
require_once 'Zend/Application.php';
 
// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);
$application->bootstrap()
            ->run();
