How to auto update a timestamp field?

[Gene Qian <ge...@yahoo.com>]

Hi, Thomas and others

I have a field, say, lastUpdated (column name:
LAST_UPDATED_DATETIME), which is used as an time
indicator and to store the last updated time of the
record, How can OJB auto set the field with new 
datetime when an persistent object was stored to DB
with a field value modified? and if no change, just
let it be.

Thanks a lot!

Gene
