No, you can use any jdbc driver that works for you. If you are not getting any error related to DB then that means it is able to connect so I do not think this is connection error. What I typically do is, I just create the database and let portal create tables etc when it starts for the first time. See if this way, you are able to connect or not. I can not think of anything else. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154491#...
