Laravel 4 putting controller in subfolder - not finding class - class

Question

I have one controller in a subfolder which works perfect:
route:
Route::resource('json/stock/equipmentImages', 'Stock_EquipmentImageController');
getting its class from controller/stock/EquipmentImageController.php
which has a class definition:
class Stock_EquipmentImageController extends \BaseController {
The strangest thing happens if I do the same with:
Route::resource('json/stock/equipmentLocations', 'Stock_EquipmentLocationController')
Then I get the message, class not found.
If I move the class from controller/stock/EquipmentLocationController.php to
controller/EquipmentLocationController.php and adjust the route to:
Route::resource('json/stock/equipmentLocations', 'EquipmentLocationController');
Everything works. This happens on a shared server without command line access. On my localhost all controllers can be put into a subfolder.

Answer 1

I wasn't using namespace which worked fine on my local host but gave issues on my public server. Namespacing everything DID solve the issues as suggested by egig. Thanks.
Here's what I did, in case others have similar issues:
I went through this nice tutorial: https://www.youtube.com/watch?v=yAzd7Ig1Wgg
to get familiar with namespacing, as this is relative new for me in for Laravel 4.
router setup (resource router):
Route::resource('json/stock/equipment', 'App\Controllers\Stock\EquipmentController');
Added the psr 0 setting to autoload: (instead of using classmap) like the video suggests.
,
"psr-0": {
"Stock": "app/controllers/"
} ....
Did not add anything to the basecontroller (no namespacing description):
class BaseController extends Controller {
public function __construct(){ ....
Added namespacing and dependencies to my controller in subfolder (controllers\stock):
namespace App\Controllers\Stock;
use BaseController, Form, Input, Redirect, View, Equipment, Response;
class EquipmentController extends BaseController { ....
Then placed my models in a subfolder (models\stock), without namespacing discription.
class Equipment extends \Eloquent {
protected $fillable = [
'description',
'location',
....
Then I did 'php artisan dump-autoload' and uploaded everything to my public server, changed database and public folder settings accordingly, because they are different. And everything worked!
Feedback is welcome, thanks for the support!
