thank you for your help , i really don t see anything wrong on the code

put your commandButton inside `` .action will fire when button inside form tag. — Subodh Joshi, Apr 04 '16 at 05:12

You cannot execute an action when the command button is outside a form. Change your code to the following:

<h:form>
<h:outputText value="#{accountController.message}" escape="false">       </h:outputText>
<h:panelGrid columns ="2" cellpadding="2" cellpacing="2">
   <h:outputText value="Username"></h:outputText>
   <h:inputText value="#{utilisateursController.utilisateurs.username}"/>
   <h:outputText value="Password"/>
   <h:inputSecret value="#{utilisateursController.utilisateurs.password}"/>
   <h:commandButton value = "login" action="#{utilisateursController.login()}" />
</h:panelGrid>
</h:form>

Hope this works out for you!

You need to change some code as per following

You need to put all element inside form body like all inputs and submit button
You need to change your manage bean name utilisateursController instead of UtilisateursController

I means

@ManagedBean(name="utilisateursController") instead of @ManagedBean(name="UtilisateursController")

Hope you will fix your problem!

please debug your code and check with managebean login method you got right user name and password and add **trim()** with username and password while you check with database. – Ravi Kavaiya Apr 04 '16 at 09:15
