Réglage du délai de connexion pour FtpClient

Bien qu'il y est de solution possible pour que les anciennes version de Communes Net de la bibliothèque, je suggère de comprendre pourquoi une mauvaise version de Communes Net est utilisée. Pour ce faire, vous pouvez inclure le code suivant à l'endroit où FTPClient est utilisé dans votre webapp:

FTPClient ftpClient = ...;
if(ftpClient.getClass().getClassLoader() instanceof java.net.URLClassLoader) {
    URL[] urls = ((java.net.URLClassLoader) ftpClient.getClass().getClassLoader()).getURLs();
    //log these urls somewhere and check - these are urls from where your FTPClient may be loaded from
}

Dans le cas où si FTPClient est chargé, par java.net.URLClassLoader alors il peut obtenir plus compliqué à vérifier le chemin de la classe, mais il ne devrait pas être un problème.

Espère que cela aide...
