bonjour, il semble que tu as une erreur ligne 143 du dispatcher.

montre ce que tu as à cet endroit.:?

voici cette ligne :
Code:

1 2 mailSender.sendEmail(fromEmail, username, password, toEmail, subject, message);

mailsender est null, donc ton EBJ n'est pas injecté. Question dans l'ordre:

l'EJB se trouve bien dans le war?
Le conteneur que tu utilise as bien un support EJB? Jetty n'a pas de support EJB par défaut puisque c'est un web profile. Donc à moins que tu l'ai ajouté explicitement par exemple avec openEJB, pas d'ejb donc pas d'injection ejb.
Quelle version de javaEE indiquée dans le web.xml ?

Je sais pas si ça peut aider mais moi je l'implémente comme ci-dessous et ça marche au poil ;)

        SimpleMailMessage email = new SimpleMailMessage();
        email.setTo("Adresse email vers qui on envoie le mail");
        email.setSubject("Ici le sujet du mail");
        email.setText("Le message du corps du mail");
 
        // sends the e-mail
        try
        	{mailSender.send(email);}
        catch (MailException me)
        	{//Wrong email syntax}

J'utilise "org.springframework.mail.SimpleMailMessage".
