Problème de sécurité d'accès d'applet à une base de données dans un JSP

**wafabrj** · 23/05/2012, 17h48

Salut tt le monde
Je fais appel à une applet java dans une page jsp. L'applet utilise un fichier qu'elle lit depuis une base de donnée grace à JDBC.
Quand je lance l'applet depuis l'application java tout marche nickel, par contre depuis la page jsp, j'obtient l'erreur:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Je pense c'est un problème de sécurité, et d'après ce que j'ai lu sur google, même si le jar est signé ça ne change rien au problème.
Quelqu'un aurait peut être une solution?
merciiii
