Hi, The attachment was removed by the email protection filter.
Can you just put the .java classes into text in the message itself? Thanks, Craig On Jul 19, 2007, at 9:28 AM, CASERO Jaime wrote:
Find attached the Holiday classes. Holiday is formed by severalHolidayElements. A HolidayElement is mainly identified by its date, butseveral HolidayElement can share the same date if they are from diffetent Holidays. Here the primary Key is formed by the date and the Holiday id (which is a foreign key to Holiday). I can't even set the "Id" annotation to a collection field (i'm using a orm.xml file for metadata).

I'm a bit confused as to whether you're talking about a ToOne relationship or a ToMany relationship being used as part of a primary key. It would help if you would post your class (just the id fields would be fine) and the id class you tried.

I have tried using an "Id class", and using "unique-constraint", but without any results. I think this is a very basic feature (A foreign key is part of the primary key) used frequently in any relational data model. Can anyone confirm this feature support?. Any simple example would be very appreciated. Thanks in advance, regards. Jaime Casero Confidentiality Statement: This message is intended only for the individual or entity to which it is addressed.
