symfony2 and throwing exception error

I am trying to throw exceptions and I am doing the following:

use Symfony\Component\HttpKernel\Exception\HttpNotFoundException;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;

I am then using them the following way:

 throw new HttpNotFoundException("Page not found");
   throw $this->createNotFoundException('The product does not exist');

however I am getting errors like HttpNotFoundException is not found etc.

Is this the best way to throw exceptions?

In the controller, you can simply do:

public function someAction()
{
    // ...

    // Tested, and the user does not have permissions
    throw $this->createAccessDeniedException("You don't have access to this page!");

    // or tested and didn't found the product
    throw $this->createNotFoundException('The product does not exist');

    // ...
}

In this situation, there'se no need to include the use Symfony\Component\HttpKernel\Exception\HttpNotFoundException; at the top. The reason for that is that you're not using the class directly, like using the constructor.

Outside the controller, you must indicate where the class can be found, and throw an exception as you would normally do. Like this:

use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

// ...

// Something is missing
throw new HttpNotFoundException('The product does not exist');

or

use Symfony\Component\Security\Core\Exception\AccessDeniedException;

// ...

// Permissions were denied
throw new AccessDeniedException("You don't have access to this page!");

If its in a controller, you can do it this way : 

throw $this->createNotFoundException('Unable to find entity.');

Try:

use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

and

throw new NotFoundHttpException("Page not found");

I think you got it a bit backwards :-)
