Hi,

I am new to hibernate and needed help on which mapping I shud use.

I have class Vehicle. This class contains an object of type VehicleType.
There can be many vehicles of one particular type. I was using a many-to-one unidirectional mapping between Vehicle and VehicleType with a foreign key in Vehicle mapping to the primary key in Vehicle Type. I was using a field in Vehicle class and in its table called FKey_vtID which was mapped to the primary key of the vehicle. I want to avoid using this extra field which will need to be checked. Vehicle Type class and table have no reference to the Vehicle. Am I using the correct mapping. IF i want to avoid using the foreign key column and still have them mapped. How shud my mapping files look like.

I wud be grateful for any comments.
Thanx

It is correct DB schema that has column in Vehicle table that points to primary key of VehicleType table.

Stick with the design unless vehicle may have several types simultaneously,
in this case you will need 3rd link table (vehicle_to_type_link).
