JSF including HTML within a method

Hi guys, is anyone able to help me? I'am still new with JSF.
I would like to create a method that holds HTML code. Then, i would like just to call that method inside my JSF page, to insert the HTML. And if there is a need to change something, i would do it in one place only.

To explain you more detaily, i'll show you how I made this in PHP.
I made file named fje.php:

Offcourse, there is a lot more HTML and JavaScript code inside functions.
Then, i would create PHP page:

Is it possible to create something like this with JSF. Or is there other way to do this?
Thanks in advance
