Example explanation:

On “helloworld.xhtml” page we have input text with id and value attribute. The value of the input text is binding with the userName property of the Test.java class. Click “Hello” button after entering the value in input text. JSF framework assign the input text value to the bean property and “sayHello” 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.

Example:

helloworld.xhtml
