Primefaces already implements jQuery UI's ThemeRoller. In your web.xml you can define a context-param primefaces.THEME with a parm-value pointing to session-scoped backing bean.

<context-param>
    <param-name>primefaces.THEME</param-name>
    <param-value>#{FooBar.theme}</param-value>
</context-param>
