I'm working on a project and have the following project layout:

```
|Project
    |-Application
        |-api
        |-configs
        |-controllers
        |-models
        |-modules
            |-core
                |-controllers
                |-models
                |-views
                |-Bootstrap.php
            |-site1
            |-site2
            |-site3
        |-views
        |-Bootstrap.php
    |-Docs
    |-Library
    |-Public
    |-.zfproject.xml

```

I've used this in my application.ini to try and set the `default` module to be the `core` module:

```
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"

resources.frontController.defaultModule = "core"
resources.frontController.defaultControllerName = "Index"
resources.frontController.defaultAction = "index"

resources.modules[] = ""

```

My problem is that for some reason, I can't get bootstraps working in the modules. It's alsmost as if the default module isn't being changed. The application behaves like it is, until I try and load the bootstraps - I get this error:

> 
> Fatal error: Uncaught exception 'Zend\_Application\_Resource\_Exception'
>  with message 'Bootstrap file found for module "default" but bootstrap
>  class "Default\_Bootstrap" not found' in
>  M:\Zend\_Framework\library\Zend\Application\Resource\Modules.php on
>  line 85
> 
> 
> 

Prefixed by this error:

> 
> Zend\_Application\_Resource\_Exception: Bootstrap file found for module
>  "default" but bootstrap class "Default\_Bootstrap" not found in
>  M:\Zend\_Framework\library\Zend\Application\Resource\Modules.php on
>  line 85
> 
> 
> 

Can anyone see where I'm going wrong?

My Application/Bootstrap.php file:

```
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
}

```

My Application/Core/Bootstrap.php file:

```
class Core_Bootstrap extends Zend_Application_Module_Bootstrap 
{   
}

```
