can we use different hierarchy stargey for each class?

amitguz Jan 24, 2006 1:28 AM

suppose I have a class hierarchy tree and I want the root class to use table_per_class stragey.
but from the middle class I want to change the stragey to single table,
can I do it?

i.e - the following class hierarchy
_______person_________________
______/________\________________
employee_______ manager________
________________/_______\________
_______Team leader____project manager

and I want this hierarchy to be translated to the following tables:

employee_table
manager_table (this table will contain data for both classes Team Leader & Project Manager)

I tried the same but it seams it is not yet supported (Alpha 3).

The only way I found is to copy all the common properties with the annotations to each root class.

I will leave that solution as long as the @MappedSuperclass Annotation is not supported and resolve the problem then by that mapping. It is exactly what the jboss-ejb3 thing needs next.

Pardon, @EmbeddedSuperclass is same as @MappedSuperclass and is supported
