Neither BindingResult nor plain target object for bean name 'loginForm' available as request attribute
Bonjour,
en fait jai vu que mon erreur venait du commandName qui n'est specifier (je l'ai mis dans la jsp), j'ai donc changer et mis commandName="loginForm" mais j'ai ceci :
Code:
Neither BindingResult nor plain target object for bean name 'loginForm' available as request attribute
