Problème "neither binding result nor plain target object for bean name"

**jerome5869** · 03/04/2012, 23h51

Bonjour,

Je réalise une application web ou j'utilise éclipse indigo, tomcat 7.0, Hibernate 4.1.1 et Spring 3.1.1.

Lorsque je vais sur ma page login, la console m'affiche le message d'erreur suivant :

org.apache.jasper.JasperException: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'loginform' available as request attribute

Voici le code de mon fichier login.jsp

Code :

Peux-tu poster la full stackTrace stp ?

Normalement, le message doit te dire qu'un 'bean' n'existe pas. Il pourrait t'aider à trouver une solution (ou à ce que nous t'aidions pour trouver la solution).

Sinon, je pense que le problème vient de là :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<form:form modelAttribute="loginform" action="/VinylRecordManager/login" method="POST">

Essaye plutôt d'écrire plutôt "login" ou "loginForm".

J'ai essayé de modifier le nom du model attribute mais ça me renvoie toujours la même erreur.

Voici la trace laissée dans la console eclipse :

**chewing-gum** · 04/04/2012, 19h19

La classe "LoginForm" ne contient pas d'annotations. Si tu n'utilises pas les annotations, tu utilises alors un applicationContext.xml.
Question : tu as bien un bean de type "LoginForm" dans ton applicationContext ?

Sinon, ce que je comprends de l'erreur, c'est qu'il n'y a pas de bean loginForm en requestAttribute

**jerome5869** · 04/04/2012, 22h18

J'ai essayé de rajouter un bean de loginForm dans application-context.xml mais ca a rien changé. Par contre, je ne sais pas quel type d'annotations mettre dans le fichier LoginForm.java. J'ai essaye de me baser sur l'exemple du site http://www.roseindia.net/tutorial/sp...m-example.html et j'ai vu qu'il n'utilisait pas d'annotations dans leur classe qui leur sert de modèle de formulaire.

Voici mon fichier Application-context.xml

Bonsoir, je ne pense pas que ce qque t'as fait puisse marcher, t'as l'url par défaut de ton controller, mais tes methodes n'ont pas d'url, je te conseillerai de de spécifier explicitement les url pour chaque méthode, sinon le plus simple c'est de faire une seule méthode qui fais les 2, parce que la tu te compliques les choses. Moi à ta place je vire la méthode getForm, et je ne considère que l'autre. Il suffit alors de tester si ton model est une nouvelle instance tu renvoies fais ce qui est dans la méthode getForm, sinon tu fais tout ce qui est dans la seconde méthode. Faut faire les choses plus simples que de les compliquer...

**jerome5869** · 05/04/2012, 13h40

j'ai essayé de modifier les méthodes de mon contrôleur et d'ajouter une annotation component à ma classe LoginForm. java mais cela me renvoie la même erreur. Je ne sais plus dans quelle direction chercher.
