the origianl question is:
======================================
what is object mapping?

A) the process of converting a class diagram to java code.
B) a program that emulates a mainframe terminal and passes user input to the mainframe.
C) the process of building object wrappers around java interfaces. this allows the legacy system to interact with your java application.
D) the process of building object wrappers around legacy interfaces. this makes the legacy system available in an oo fashion.
======================================

the given answer from javaqueries is A). but mine is D). the answer of A) seemly is in the OO knowledge category. but the OBJECT MAPPING is related with the legacy connectivity.

and your comments? thanks.

re: why not C?
C) the process of building object wrappers around java interfaces. this allows the legacy system to interact with your java application.

object mapping is using java to wrap the legacy system and to connect to it. the answer C is inversed.
