Deploy to Oracle Database but no table found

Hi,

My J2EE application was deployed to JBoss and the tables got created in its Hypersonic DB. It worked fine. RIght now I want to have them created in Oracle database. I changed to data source file to oracle-ds.xml and got rid of hsqldb-ds.xml. I also changed DataSource to OracleDS and gave the correct Oracle DB connection in my deployment descriptor. Then I deployed to JBoss and was told deployment sucessful. But I can not find the tables that supposed to be created under my Oracle database. Does anyone know why?
