Brett,
80% of my model objects have immutable interfaces. It works so good for
thread-safety. If I ever need to alter an object, my model objects have
a copy constructor that accept an instance of the interface.

Does anyone have a pattern for creating read only fields?
While I am obviously not persisting the RO properties having to have the
setters as public methods is bad design. Is there any downside(from an
iBatis POV) to exposing an interface as the business class and using a
concrete class for managing persistence (see below) ? Does it seem
pointless to worry about?
interface modelObj{
A getA()
}
class iBatisObj implements modelObj{
public setA(A a);
public A getA();
}
