Andreas,
The error message indicates that the java.sql.DriverManager cannot find a
'suitable' driver, becasue no driver for the URL prefix 'jdbc:oracle' has been
registered. I just had a look at your DataSource definition again, and it seem
to me that the following property must be wrong:
driverClassName="oracle.jdbc.driver.OracleDriver"
clearly, the package name for the OracleDriver is wrong .. ;-).
