Mon code est ci-dessous

<!-- The bare minimum needed for JSF 2.2 is a servlet 2.5 or later
declaration (this uses 3.0) and the mapping for the FacesServlet.
Setting PROJECT_STAGE to Development is highly recommended
during initial development so that you get more helpful
error messages. Whether you want server-side state saving
(default) or client-side is a more complicated question:
client-side uses more bandwidth but fewer server resources.
Client-side also helps to avoid the dreaded view expired exceptions.
