Example explanation:

On “test.xhtml” page we have inputSecret with value attribute. The value of the inputSecret is binding with the password property of the Test.java class. Click “Check Password” button after entering the value in inputSecret. JSF framework assign the inputSecret value to the bean property and “checkPassword” method returns the “success”. This return value is matched with the navigation rules defined in faces-config.xml file and renders the welcome.xhtml page which shows the entered password value.
