I need a very specific mapping. Let say I have a class having ListArray of values.

How can tell Hibernate engine how to map these values into a database in real time. No hbm files should be precreated and no annotations eather.

Is there any mechanism, that I could say:

PersistentObject po = manager.loadPersistentObject("Person", 23);

po would need to be mapped to database in real time, as manager would check the type of an object from class repository, where entities are defined.

Thanks in avdance.
