There is no performance difference between JBoss AS (community version) and JBoss EAP (enterprise version). The error is expected. The messaging server checks to see if the database is initialized when it first comes up. If it isn't, you see these DEBUG statements (note that it is not an error) in the server log. The messaging server then creates the tables. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4137619#...
