Advanced O-R Mapping

[Hamidou DIA]

Hi,
I am trying to use the Orion advanced O-R mapping
features. I have an entity bean "Event" which contains
a Collection of "Attachements". At deployment time,
Orion creates a perfect table for Event but the
Event_Attachements table is created with one column of
type LONG RAW. How can I get Orion to create the table
with the attachements fields.
I have attached an extract of my bean class and
orion-ejb-jar.xml

Thanks for your help.
