<jsp:useBean> K&B Standard Action Question on page 358.

[Marcelo DeOliveira]

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()}

<jsp:useBean id="person" type="foo.Employee" scope="request" >
<jsp:setProperty name="person" property="name" value="Fred" />
</jsp:useBean>
Name is : <jsp:getProperty name="person" property="name" />

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

foo.Person p=new foo.Employee();
p.setName("Evan");
request.setAttribute("person", p);

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?
