Do this: 1) Copy docs/examples/jca/postgres-ds.xml to server/xxx/deploy 2) Edit the postgres-ds.xml to contain information for your database. 3) Add a < metadata > entry to postgres-ds.xml (you need this to get some of the services to work correctly): <datasources> | <local-tx-datasource> | . . . | <metadata> | <type-mapping>PostgreSQL 8.0</type-mapping> | </metadata> | </local-tx-datasource> | </datasources> 4) Delete the server/xxx/deploy/hsqldb-ds.xml file 5) Start the server. Any required tables are created automatically. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4049380#...
