But by using aforesaid URL showing below error:

Answer 1

Whenever this happened to me was because I hadn't created a menu entry for my new controller.

What I'd advise you to do is to go to Administration > Menus then created a new entry.

Fill in the form like this :

Name: Productarticle  
Class: AdminProductarticle  
Module: productarticle (if that's the name you gave your module)  
Active: NO (this way you don't have to have a menu entry that's gonna be useless to you)  

On top of that you should have something like this in your __construct()

class AdminProductarticleController extends ModuleAdminController
{
    public function __construct()
    {
        $this->module = 'productarticle'; //refers to your module's $this->name = 'productarticle';
        $this->bootstrap = true;
        $this->context = Context::getContext();
        //The following 2 lines are useful if you have to link your controller to a certain table for data grids
        $this->table = 'contribution';
        $this->className = 'Contribution';

        parent::__construct();
    }   
}

From this point onwards everything should be fine.
