Seems to me that last santuario has something wrong: anyone know something about? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/725340#725340] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
