To represent inheritance, how many hbm files are needed?
How can I represent the relationship between base and subclasses in the subclass hbm file?
I want hbm class and pojo super and subclass.

Use the "extends" attribute for subclass, join-subclass, or union-subclass members. You can put all the classes in the same .hbm file, or split them into separate files if you like.
