Hi,

I have a complex object, which has no equival table in my database schema.
This object is composed of another objects, which do have tables in dbs.
The question is, how to write an .xml mapping file, so that I will call:
myComplexObject.save()
and it will take all the subobject, and save them to the corresponding tables.
(I stucked up at the .xml file creation, ... do I need the table element for my complex object? (I have no table!)

OK, I JUST want to know:

<class ...

Do I need to declare a 'table' property? (In fact I can't declare, becauce I have no table for this complex object)

<subclass >......</subclass>


</class>

p.s. sorry, if those questions are too trivial, but I'm really a newbie

You use the class/subclass mapping for defining object hierarchies that map at some level to tables - table per hierarchy, table per class etc.

If your complex object is composed of objects that are Hibernate objects, then your complex object does not have to be mapped to Hibernate itself. You would implement find, save etc in the complex object which would do the underlying Hibernate work. I would not model things this way, as I would rather use transactions and surf the object model as I needed, but I don't know your particular situation.
