Hello !!!
I have a little problem. I'am developping a web application (with Netbeans, glassfish
and hibernate). In a page, the client must fill a form and when I click on the button,
there is this exception :
Exception during request processing: javax.servlet.ServletException:
/abonnement_contact.xhtml @45,70 value="#{contactel.firstName}": Target
Unreachable, identifier 'contactel' resolved to null
my jsf page :
