Then the reason was OracleTypes.CURSOR which is specific to Oracle. With JBoss similar things can happen: the JEE container wraps JDBC connections with its own wrapper class to be able to cache PreparedStatement and handle XA logic. Whenever you need functionality which is specific to the real driver used underneath you need to obtain the wrapped connection and work with that.
