I am using proxy objects, dynamic proxy objects, maps in my project. Does hibernate provide any API to persist these in the DB tables

Say for example

The proxy object has two fields, userID and userName. I need to persist these two in the User table which has exactly 2 columns userID and userName.

Or instead I have a map that has these two values. Can I persist the map directly to the user table in database using Hibernate API.

I don

In my earlier post, I have asked for ways to persist maps directly.

And while retrieving from the database, hibernate gives it as a collection of objects.
Instead can it give as a collection of Maps.

If there is no direct way to do that, can this feature be added to Hibernate?

I would appreciate if some one could help me out in this regard.
