Ivan describes a nice distinction between Plain Old Java Objects in general and Non Object-oriented Java Objects in particular.
Certain (web, in particular) frameworks lead on in the direction of NOJO's. It begins with the DTO (just one kind of NOJO) and spreads from there. Is that good or bad?

Do you like them?
