Thanks a lot for your very helpful message. I have tons of logs and screen captures, but before re-posting them, again, I decided to make that simple question. Just wanted to make sure I was copying the right files from "all" to "default" instance to use JBoss Cache. Nothing more in this thread. Any way, please have a look at my previous messages: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=124299 and http://www.jboss.com/index.html?module=bb&op=viewtopic&t=124817 I didn't find it necessary to repost al this for just a question, but maybe I should have. I very much thank you for your positive help, Ignacio View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4109203#...
