Bonjour à tous,

J'ai une applet qui dans la méthode init() contact la servlet pour initialiser divers champs/liste de mon applet.
Je fait fonction mon applet en remote(enfin j'essaie...)
j'ai une exception lors de de l'appel à getCodeBase() => null.
Voici un extrait de code qui plante :

Code:

System.out.println("FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF");
	URL urlServlet = new URL(getCodeBase(), "/gestionCandidatures/InterfaceClient");
        System.out.println("GGGGGGGGGGGGGGGGGGGGGGGGGG");
	URLConnection con = urlServlet.openConnection();
