Laravel 4 class not found error

Laravel 4 class not found error

I'm getting an error that a class (a controller) is not being found. Thing
is, it is found in my local development environment. I created the
controller with php artisan controller:make CssController
--path=app/controllers/home.
I renamed the class (not the file) Home_CssController. I added the route:
Route::get('home/css-php', 'Home_CssController@index');
to my routes file. Everything works fine in my local environment. I did
forget to run composer dump-autoload but there were no issues with viewing
the controller/view in my local environment. I've uploaded everything to
the live server, but I'm getting the error:
Class Home_CssController does not exist
I've uploaded the controller, the routes file and the view multiple times.
But I still get the error. Is it because the controller wasn't registered
with composer? I've since registered it, but am not sure what I need to
upload to the server. I've uploaded both the config and bootstrap folders.
What do I need to do to get the controller/view to be found? This is
Laravel 4.
