Hello,
i'm a little bit confused how to model following situation:

I have a entity DescriptionItems which has an attribute Locale to be independet from different languages, and the descritption itself.

Now i have two furter entities:

Entity A: Has a Map of description items called logicalDescritptions and a Map technicalDescriptions

What is the best way to implemnt this relationship? One solution is to implemet a 3rd Entity descriptionsBag to contain the relevant descriptionItems for either logical or technical Descriptions, but i'm afraid that's not the best pratise because i don't wanna implement an extra class only for satisfy hibernate....

Hope for help....

I would map this as follows (using sets instead to maps):

@Entity
public class A
{

@OneToMany()
Set<DescriptionItem> logicalDescriptions = new HashSet<DescriptionItem>();

@OneToMany()
Set<DescriptionItem> tecnicalDescriptions = new HashSet<DescriptionItem>();

}

Thanx for reply...

Ok..that will produce two join tables, each per association.....

I'll try to find a way to produce only one with the id of the join table in the relevant "A" tables attribute...Is this possible w/o creating a descriptionBag Class?

best wishes.
