I would like to make it more beautiful and customize it with my own markup and a bit of css.

-Do i need to program that on my app or i have to configure that in the application server?

You can declare custom <error-page>s in web.xml depending on <error-code> (the HTTP status code) or <exception-type> (the full qualified exception class name which was been thrown, e.g. javax.faces.application.ViewExpiredException).

<error-page>
    <error-code>404</error-code>
    <location>/WEB-INF/errorpages/404.xhtml</location>
</error-page>

You've all freedom to fill in the markup in 404.xhtml.
