Hi.
I'm working on a small system and I want to achieve the following results. I want to have two entities, User and Group, which basically look like this:
class @Entity User {
@Id int id;
@ManyToOne(option=false) Group group;
...
}
class @Entity Group {
@Id int id;
@OneToMany(mappedBy="group") List<User> users;
@OneToOne User owner;
}
What I want, is to be as sure as possible that if
user is the owner of
group then
user.getGroup.getOwner = user and
group.getOwner.getGroup = group.
How is the best way to add those constraints on entity level (and not in the session bean logic, since I want to add another layer of security here).
