Bonjour =E0 Tous,

Je voudrais utiliser des Generics dans des objets faisant partie des
signatures de m=E9thodes de mes WS (sous Jonas 5.1.5, via JAX-WS / CXF).
Mes WS sont impl=E9ment=E9s sous forme d'EJB 3.0 / JAX-WS.

Pas de souci pour g=E9n=E9rer les classes clientes et server (via
wsgen/wsimport).

En revanche, au runtime, je me prends une erreur du genre :

glurps !

Il semblerait que JAXB (sous le capot de JAX-WS) ne marshalle pas

Si vous avez de l'info =E0 ce sujet, je suis preneur
Merci d'avance
