Create and Deploy a Oracle Datasource
Then create a text file in the deploy directory called oracle-ds.xml with the following datasource descriptor : DefaultDS jdbc:oracle:thin:@localhost:1521:xe oracle.jdbc.driver.OracleDriver SYSTEM jboss org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker Oracle9i The datasource is pointing at the database/SID called xe provided by default with Oracle XE. Of course, you need to update the connection url attributes as well as the username/password combination to match your environment setup.
