JBoss Portal uses Hibernate for its database access, and Hibernate supports Ingres, though it is not one of the regularly tested databases. Also, Portal probably has not been tested on Ingres. You are welcome to try but your results may vary. You can always ask about problems you run into but unless there is another forum reader who is also using Ingres you might not get too much help. Hibernate should detect Ingres automatically. If it doesn't, the Hibernate config files are at jboss-portal.sar/conf/hibernate/*/hibernate.cfg.xml View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4226977#...
