bonjour,
en fait ce que je voudrais savoir c'est la signification du message :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

javax.servlet.ServletException: Define tag cannot set a null value

merci d'avance de votre réponse

Dans ton code il y a une variale que ta initialiser a null ou qui se retrouve en chemin avec un null, check ton code
