Bug: https://hibernate.atlassian.net/browse/HHH-3159

Oracle does not support Hibernate, however this appears to be an issue of configuration rather than a Hibernate bug.

see:
https://community.oracle.com/thread/700746?start=0
Problems of hibernate calling oracle stored procedure 

Please try the following:
1) change the connection.driver_class property in your hibernate config file to oracle.jdbc.OracleDriver
2) upgrade the Hibernate to Hibernate Core 3.3.2 GA has a fix for this problem as indicated in the above community thread
( Oracle Support has not verified this directly as we do not support Hibernate).

Please note that it is extremely unlikely that JDBC development would agree to open up the oracle.jdbc.driver package so a patch request would most likely be rejected.
