Google is your friend: http://wiki.jboss.org/wiki/Wiki.jsp?page=SetUpAMysqlDatasource shows how to use mysql under jboss in a couple of minutes. I can't help you with the hsql db manager, as I don't use hsql. Yes sorry, I mistyped servers instead of server. That is the directory you want. Assuming I don't want to read copious amounts of documentation, how would I do this with RoR? I'm just curious, as I've heard a lot about Rails (both good and bad). Anyhow, I will say, as someone who still doesn't have a solid grasp on much of JBoss, that reading documentation is a must for understanding a new technology, and that JBoss is likely to be VERY different than RoR, or any other non-J2EE Java based app server.
