Re: OJB and inheritance

Hi,

I am using OJB for the first time. I have three tables, say T1, T2 and
T3. These tables are the ER representation of three java classes C1, C2

and C3. From the object orientation point of view C1 is the super class

of the other two.
When I had to map the classes with the tables I've used the "table per
subclass" method (map every subclass to a distinct table).

The problem is :
when I try to delete an Object of class C2 I expect that OJB delete the

C2 object and even the referenced C1 object. But this does not happens.

How could I achieve this behaviour?

Define CMR between the entity beans and cascade delete on the relation?
