When JBoss start success, I open mySQL and I recognize that: anonymous wrote : On B machine, BDatabase have some tables: hilosequences, jms_messages, jms_roles, .... | But on the C machine, CDatabase has not some tables as BDatabase. ---> Why CDatabase has not (if datasource has been successfully bound to the JNDI name)? I haven't operated with CDatabase ! But I think that if my datasources (include BDatabase and CDatabase) has been successfully bound to the JNDI name ---> Both of them must have some tables (as above). But only BDatabas have ! Please guide to me why ! Thanks. catania. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092897#...
