Closing Browser When User Clicked On Logout

When user clicked on Logout button/link in JSF page, we can call Javascript to close browser window.

This can be achieved through 2 different ways.
1. We can directly call JavaScript using clientlistener for command button. This method more faster.
2. We can call Java method to execute Javascript using RenderKitService API. This method allows to perform any logic on server side during logout.

Following Sample Code Snippets will help you to do it.
