Re: Bidirectional 1:1 relations

Armin thank you for your reply,

I came to a solution proposed to another OJB mailing poster (Luis
Cruz) that works with me and suggested that I could invoke the
getUniqueValue() in the DomainObject super class... its ugly but it
works fine... and it happens to be a controlled ugliness.

I was now wondering... is it possible to map an object to two distinct
columns of the same table? I mean if I have

class Point
{
int x;
int y;
}

and
B
{
Point p;
String name;
}

Can I use the B table to store the points? I was thinking about a
table with the following schema:
create table B (name varchar, point_x int, point_y int);

I read the rowreader tutorial but it doesn't seem to fit my needs.

Thank you once again!

Best regards,
Gonçalo Luiz

Hello again,

Kindly forget my last e-mail I was looking to a old page of OJB that
was cached somewere... I think that the
http://db.apache.org/ojb/docu/guides/advanced-technique.html#nested-objects
page wil serve my needs... if it doesn't I will let you know.
