Thanks for your reply! I really appreciate it!! I see what my error was. I used a pojocache-passivation-service.xml for the config file when I was only testing on a local machine with no network connections. You really need to be aware of what is in the config file. I changed to cache-config.xml with very simple entries and it works fine. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4070841#...
