Hi,
I've got some problems in mapping my Data Model in Hibernate, I don't think it is an uncommon problem, but I didn't found anything about this in my searches...

My tables are these:
TableA : ID_ENTITYA (other A data)
TableB : ID_ENTITYB (other B data)
TableC : ID_ENTITYC (other C data)
TableD_Link_A_and_Entities: ID_D, ID_A (foreign key with TableA), TYPE_ENTITY, ID_ENTITY

My problem is to mapping the generic associations described by TableD_Link_A_and_Entities where the couple of columns TYPE_ENTITY, ID_ENTITY specify the entity associated with EntityA (ex. if TYPE_ENTITY=B then it's an EntityB, if TYPE_ENTITY=C then it's an EntityC)

I'd like to have a resulting Persisten Class like this:
Class EntityA {
getEntitiesB()
getEntitiesC()
...
}

Any suggestions?

Hibernate version:3.1

Name and version of the database you are using: Oracle 10

Every suggestion is appreciated!!! Indeed!!!
