page 358 of HeadFirst S&J states:

There is a concrete Employee Class {int getEmp(), void setEmp()} that implements an abstract class Person {String getName(), void setName()}



Question?
What happens if the code below forwards the request to the jsp above?



The answer on page 420 states that it will FAIL at request.
If the Bean exists on the request scope with value "Evan" why does it fail?
I am missing something but I don't know where.
Thanks,

I have tried above code but it does not fail. I think you too should try once.

Is the answer on the HFSJ2.0 wrong on the book. Is there an errata for it that i missed?
