Flame me if I am asking the "open door type" of question here, but having a look in the jboss.jcml file I see that the username and passwords are fixed for the DataSource. It implies that I can only use a single set of username/password to access the database. With multiple groups of users around, this is not a very desirable situation for the application I am creating. Data must only be shared within a user group!
So, how could I arrange a situation where I can introduce a new DataSource dynamically whenever a first user of a new group registers? After restarting JBoss the DataSources should be recreated automatically.
