Hi,

I was wondering how to do a simple per-class-hierarchy mapping for an object graph 3 levels deep. For example, say I want to map the abstract base classes X <-- Y <-- Z. I assumed you can nest the <subclass> element in order to achieve this but I'm not getting the result I want when hibernate generates the schema. Here is my map:






I would assume this is the correct way but I know it is not since I'm not getting the schema generated accordingly (Y and Z are linked to X). Any help would be appreciated. Thanks!

Hi,

I've been trying to get more than 2 levels of this inheritance working but it seems that the way the hibernate mapping is structured, you can not define a subclass of a subclass within the same class element--i.e. X <-- Y <-- Z is not possible, only X <-- Y and X <-- Z (only 2 levels deep). I tried a similar mapping using mixed inheritance--per-class hierarchy and per-subclass-- but I still could not get it to work... see my other post for code example:

Looks like I'll have to try something else or keep everything flat...

Hi,

why don't you create a mix of table per class hierarchy and table per subclass ?
