and without MVC pattern.

But it’s generating a fatal Error

Fatal error: Call to a member function redirect() on a non-object in 

Please help me out guys, you guys may be expert in joomla component devopment.

Answer 1

You get the error because Joomla! 2.5 doesn’t have a global $mainframe object, that is a hangover from Joomla 1.0 days. In Joomla! 1.5 it was a legacy support feature.

You can use the the following to replace your $mainframe:

$jApp = JFactory::getApplication();
$jApp->redirect($url, $msg);

If you’re updating old code to work with Joomla! 2.5 you should read this article which covers these sorts of issues.
