Probably the best list of supported database is under the heading "Set up specific DataSources" at http://wiki.jboss.org/wiki/ConfigDataSources. But as Jaikiran noted, any JDBC data source will work. At work we have JBossAS running with several databases not listed on that wiki page, but then when it came to configuring things like messaging and timers, we often had to hand-modify the SQL statements in the configuration files.
