Unable To call function from URL

[eluser]Blue Sapphire[/eluser]
Hi!
I have following class code :

Code:

<?php

class Main extends Controller {

    function Main()
    {
        parent::Controller();
    }
/****************************************************/    
    function index()
    {
        echo 'index Function';
        //$this->load->view('admin/adwc');
    }
/***************************************************/    
    function myFunc()
    {
        echo 'Another Function';
    }
/**************************************************/    
    
}

?>

I have set route in routes.php as follows:

Code:

$route['admin'] = "admin/main";

I am using following url:

1- http://localhost/personal/com/admin/ [This works fine and shows message]

2- http://localhost/personal/com/admin/myFunc [This url gives me '404 Page Not Found' error].

Can some one guide me where I am wrong and in solving this problem.

Thanks in advance
