hi!

Is there a way in hibernate to map an entity across two tables (the tables referenced by a foreign key, of course).

Thanks!

Please see "delegate" pattern on the Wiki.

Thanks Gavin!!!

To those of you who wanna find out where the wiki for delegate pattern is:
http://www.hibernate.org/45.html

I have a similar problem.
I read the "delegate" pattern and it doesn't work for me.
The problem is that the example is using the
<generator class="assigned"/>
I think it should use "foreign". With "assign" I have to assign the id manually.
Example:
session.save(customer);
customerHistory.setId(customer.getId());
session.save(customerHistory);
I think this doesn't look good. What if I have 5 objects like CustomerHistory?
I may be wrong, I am newbie with the hibernate. I accept any notes on that (on my English too).
I know that I can use joined-subclass. But it is not good for me too.
I have the following problem:
3 tables

EMAILS, EMAIL_BODY and EMAIL_SOURCE.

They all have primary key EMAIL_ID and the relation is one-to-one.
How can I do without double extending the Email object in JAVA. I
I would like to use lazy loading of the EMAIL_BODY and EMAIL_SOURCE objects.

Thanks in advance to any response.

I tried OJB before hibernate and I was not able to that again.
I used many-to-one relation and with some methods added it worked good.
I'm sure this workaround will work with hibernate too.
