Hazarding a guess, you need to look at f:view locale="#{bean.language}" where the language property is
something like "en", "es" or "fr" and you have files like messages_fr.properties and these are supported-locale's
in faces-config.
The bean should be session scoped and you also need to change the locale in the view when the user selects
a new language:
Also it's recommended to use h:selectOneMenu onchange="submit()" to synchronously refresh the page.
