Yes, then class A instead has a reference to a class QualifiedARef (or a collection of these). QualifiedARef holds the relation info and a reference to the target A. If bidirectionality is important, it can hold a reference to both of the As in the relation.

Hi Phil,
Thank you for your answer.
Is it also possible if you qualified this self reference (add information about relation)?
For example if class A have a reference to another instance of class A and this reference has information like reference_name or something like that.

Sylvain

Hi Sylvain,
OJB handles self references fine. In other words class A can have a reference to another instance of class A or a collection of class As. You may need to make these proxies if the graph is very large and you need to control the hits to the db.

Hello, I have a situation with recursive relationship:I have a class Software that represents the softwares that could be installed on my machine. Some of these softwares must have other softwares installed before to be able to be installed. So, I have a recurvive relationship here. How do you implement this relationship with OJB?
