magento controller not found - magento

Question

I have set up a controller in my module to add an order export tab to my installation:
in config.xml:
<admin>
<routers>
<adminhtml>
<args>
<modules>
<orderexport>abc_Orderexport_index2</orderexport>
</modules>
</args>
</adminhtml>
</routers>
<layout>
<updates>
<orderexport>
<file>orderexport.xml</file>
</orderexport>
</updates>
</layout>
</admin>
in adminhtml.xml:
<?xml version="1.0"?>
<config>
<menu>
<sales>
<children>
<orderexport>
<title>Order Export</title>
<sort_order>20</sort_order>
<action>adminhtml/index2</action>
</orderexport>
</children>
</sales>
</menu>
<acl>
<resources>
<admin>
<children>
<sales>
<children>
<orderexport>
<title>Order Export</title>
<sort_order>20</sort_order>
</orderexport>
</children>
</sales>
</children>
</admin>
</resources>
</acl>
</config>
and in the controllers/Adminhtml/Index2Controller.php file
class abc_Orderexport_Adminhtml_Index2Controller extends Mage_Adminhtml_Controller_Action
{
public function indexAction()
{
$this->loadLayout();
$this->renderLayout();
}
}
However with all this done, whenever I click on the button "Order Export" it redirects me to the 404 page. That means that Magento cannot find the controller but idk why.
When i rename the controller everywhere from index2 into index (Index2Controller.php to IndexController.php) I am not getting redirected to the 404 page, HOWEVER the Dashboard of the admin panel just reloads.
I really don't know where my error is and Im happy for any hints into the right direction.

Answer 1

Here is what you have to fix:
in config.xml: you have to say that your module should be use in the adminhtml area, and you have to respect the CamelCase, here is how it should look like:
<admin>
<routers>
<adminhtml>
<args>
<modules>
<Abc_Orderexport after="Mage_Adminhtml">Abc_Orderexport_Adminhtml</Abc_Orderexport>
</modules>
</args>
</adminhtml>
</routers>
</admin>
in your controller, again, you must respect CamelCase, i.e. the class name is Abc_Orderexport_Adminhtml_Index2Controller
All this is assuming your folder structure is:
app/
code/
local/
Abc/
Orderexport/
controllers/
Adminhtml/
Index2Controller.php
etc/
config.xml
adminhtml.xml
, exactly, upper/lower case is important

Answer 2

Could you please try the following code and make sure that you module class name and folder structure must be in standard magento
extension structure. config.xml
<admin>
<routers>
<orderexport>
<use>admin</use>
<args>
<modules>
<orderexport>Abc_Orderexport_Index2</orderexport>
<frontName>orderexport</frontName>
</modules>
</args>
<orderexport>
</routers>
<layout>
<updates>
<orderexport>
<file>orderexport.xml</file>
</orderexport>
</updates>
</layout>
</admin>
