I have installed Jboss successfully and trying to replace the HSQL DefaultDS with Oracle. 1. Renamed JNDI name on hsqldb-ds.xml 2. Copied oracle-ds from examples/jca and supplied neessary parameters. 3. And named the oracle JNDI datasource name as DefaultDS. When I start the server, it comes up without anyissues. My questions are: (a) Should I see any tables on database created by JBOSS ? (b) What's a simple test that I can do to make sure that JBOSS is indeed using new data source and works fine.
