Can anyone tell me if it is possible to map an abstract class? It doesn't look like it's possible, but maybe I'm doing something wrong. For example, I want to do something like this:



where BaseClass is abstract. It looks like Hibernate requires that BaseClass be concrete (and also have a no-arg constructor, etc.) even though there are no actual records with that type. I can, of course, map each subclass separately, but then I have to duplicate the properties. It would be more convenient if I could map it as above.

Thanks

Hi,
We had a similar problem. I think it is not possible to have an abstract class as in the Hibernate it tries to get a new instance of the class ( AbstractClass ab = new AbstractClass and it fails there).
So what we are doing is, have that as a normal class with all the methods and getter / setter for all the fields and the other classes extending this class.The other classes will have just their respective getter / setters.
Also there will be only one hbm file for the parent class.
That way we can avoid duplication

Of course you can, just as explaine here http://www.hibernate.org/hib_docs/reference/en/html/inheritance.html
