Hi J?r?me,
Yes, it is. Your base class will also have to declare the methods you
want to wrap with toString(). These get overridden by the subclasses.
For example, BaseClass.java wraps USAddress.getName() with toString().
Main.java calls address.toString(). If you drop these in
vendor-extensions and run ant, you see:
ant
Buildfile: build.xml
compile:
.
.
run:
[echo] Running the sample application...
