Generate POJO's from Database types

Hello!

I am using PostgreSQL with stored procedures a lot.

Each procedure returns me a specific type so I can do something like this:

            Query q = em.createNativeQuery("SELECT filename, image_id FROM mySchema.userImages(?,?,?);", Image.class);

the ORM frameworks allow me to generate POJO's based on tables, but I cannot use the tables, just the types
