Hi, i see... ok if you want just a MYSQL datasource foryour own purposes, it's enough to do step 1/2/3, configure mysql-ds.xml and proper authentication in login-config. All jboss MQ that comes with default dist i gues it is using hsql as database, so if you would have gone to do steps 5/6 that mean to me that you want tocompletely replace hsql with mysql, having mysql db handling everything, at least, that's what looks to me by checking the link you provide i have been using mysql with jboss for over 3 years, and all i needed todo was to configure properly a mysql-ds.xml that's what it seems to me you want to do hth marco View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999982#...
