Bonjour !
Je me suis mis au JSP/servlet il y a peut et il y a quelque chose que je ne coprend pas ...
le JSP est il vraiment du java sun 5.0 ou s'agit il d'ue réimplentation d'un interpreteur spécifique ?
en effet je me pose cette question car je n arrive pas a utiliser les générics en JSP ... c'est peut etre normal mais si c'est le cas je trouve ça bien dommage...
voici mon code :
ArrayList<String> products = (ArrayList<String>)request.getAttribute("products");
et ça renvoie ça :
