Hibernate version: Latest

Is it possible to define a joined-subclass in a separate mapping file to the parent class? I've got a lot of classes that all inherit from a single class, and it means putting all the mapping information into one file.

I've searched the documentation (& Google) for an answer, so apologies if this has been answered before.

TIA

use extends=".."

yes AND remember to add the superclass BEFORE the subclasses otherwise Hibernate won't be able to resolve the extends reference properly.

Thanks guys - that works a treat.

I was wondering why I couldn't define another <id> in my derived class, but thinking about it, I like the way Hibernate makes it more like Java inheritance.

Don't know if you guys are involved in the development of Hibernate, but I think it's a great product and I've only just started playing with it.

Thank you - hope you enjoy the Hibernate experience ;)

i have a joined-subclass which i would like to keep in it's own mapping file and refer to it's superclass using the "extends" attribute, but when i try to run my app, it complains that it cannot find the parent class.

can you please explain what you mean by this?

i have all my mapping files in one directory, which in turn is part of my classpath. how can the order of the mapping files be specified so that it picks up the superclass BEFORE the mappings that have joined-subclasses in them?

thanks!

Max was of course talking about the order in hibernate.hbm.xml

...and you control that by either explicit stating them in a cfg.xml or do it in proper sequence when adding them to your configuration object.
