Insert into date column using EJB3.0 and toplink not working

Question

Hi All,
I'm getting the following error whenever I attempt to insert a date value into my Oracle database.
[TopLink Fine]: 2006.08.08 05:53:21.973--UnitOfWork(14806807)--Connection(14714759)--Thread(Thread[RMICallHand
ler-0,5,RequestThreadGroup])--
INSERT INTO EMP (EMPNO, ENAME, SAL, HIRE_DATE) VALUES (156, 'John', 2.0, {ts '2006-08-08 17:53:21.973'})
[TopLink Warning]: 2006.08.08 05:53:22.036--UnitOfWork(14806807)--Thread(Thread[RMICallHandler-0,5,RequestThreadGroup])--
Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)):
oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: ORA-00904: invalid column name
The cause seems to be clear enough; from the sql above it seems that the timestamp syntax isn't being interpreted properly by either toplink or the JDBC driver , (I'm using whatever driver that comes with OC4J 10.1.3).
I've seen somewhere that you can call setUseNativeSQL() in toplink but how do I get hold of the toplink session from an entity bean?
That sounds like an awkward workaround anyway, what other workarounds are open to us?
Thanks,
C

C,
I don't use TopLink, but I suggest you set the "processEscapes" [Oracle database connection] property to "true", as described in the JDBC User's Guide and Reference.
Oracle documentation can be accessed from here:

Good Luck,
