Why does iBATIS need to know anything about the interface?

The other guy is right. Ibatis thinks there is no setId on the Person
because Person interface is read-only, although in the sqlmap I am
constructing a PersonImpl on an ArticleImpl.
I believe ibatis can be changed to solve this problem: Assuming that ibatis
constructs inner objects as it navigates (does it?), it should use the
instance it creates rather than looking at the type from the getter.
Otherwise I will have to have a diferent getter on my object just for ibatis
that returns the impl.

How often do you swap out the implementation of your beans? ;-)
