So I use this commande : | [...] | WEB-INF/lib/force-quartier-facturation-020708.jarWEB-INF/lib/force-quartier-force-020708.jarWEB-INF/lib/force-quartier-livraison-020708.jar | [...] | It display all the content of the webapp, the VoAdrEml isn't inside WEB-INF/classes because it is inside the ejb-client-jar ... WEB-INF/lib/force-quartier-force-020708.jar ... which appear in the webApp content. I remember that the webapp is class loader isolated. I don't understand why jboss can't find this class but load successfully the VoPdv class which is in the same WEB-INF/lib/force-quartier-force-020708.jar.
