:useBean id="person" type="foo.Employee">
<jsp:setProperty name="person" property="name" value="fred" />
What happens if the
code looks like;
foo.Person p = new foo.Employee();
This is the question on page 416 of HFS
My questio is, that in usebean we mention type to be "foo.Employee"
but in servlet we have type foo.Person... is this not an error..

Even though the reference type is Person in servlet but the object is of type of Employee.
So, you can mention reference type as Employee in usebean.
It is sorta covered in the
JavaRanch Style Guide
subject: page 416
Polymorphism of the jsp:useBean
jsp:useBean standard action doubt
Is this an error in HFSJ ??
