Why aren't you using some kind of ORM? At least use a light-weight library for translating data base entities into objects. Also JPA will do some kinds of automatic instantiation for you: I didn't check to see if those are the most recent docs (I don't use this sort of feature). Google for "JPA table inheritance" and check through the results carefully. > Class is a simple version containg only the important parts. Honestly, while we all appreciate the attempt, you example is far from complete. We can guess at a few things, but you should think much more carefully at what the real problem is and design something to illustrate it.
