Greetings. I went and fixed the 'table not exists' error by adding it in the database. Problem is, any and all actions on any other connection, including this one, that did not access that table also all failed, with the indicated ClassCastException/ClassNotFoundException. And its not just table not exists. IllegalArgumentExceptions and NullPointerExceptions both take the Cache down the same way. -Steve View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138335#...
