Hi,
I am new on Hibernate (even if I read and I have tested for several days) and I need help for a hard part of my project.

I would greatly appreciate If a "hibernate guru" could spend some of his precious time to help me doing the mapping.

Here is a little part of my model. If I could understand how to manage that with hibernate, I think I will then could be autonomous.



A "party" can be either a worker, a client of type organization or a client of type person.

In the case of a worker or a client of type person, the personal data concerning the "party" are stored in the "Person" table.

When I retrieve a worker from the database, I should be able to know his name and if he is enabled or disabled.

When I retrieve a client of type person, I should be able to see his name and an optional comment.

When I retrieve a client of type organization, I should be able to see its name and an optional comment.


In my class model, I would have classes
- Worker
- Client
- ClientOrganization (extending Client)
- ClientPerson (extending Client)
- Party

and the interface Person implemented by Worker and ClientPerson.

I have read a lot of examples about different types of mappings but nothing really close of my need.

For now, I have generated the java classes and mapping files with Hibernate Tools in Eclipse. The result is good and I already can insert and retrieve data but I dont know how I could tune my configuration to make the data and classes model closer.

Thanks a lot for any help or suggestion
