If I have
- class employee
- interface person

As I understand that I can use

<jsp:useBean id="emp" type="test.person" class ="test.employee" scope="session" />

But I don't understand in what circumstances that I would need both class and type together.

If you want to use polymorphic behaviour
<jsp:useBean id="emp" type="test.person" class ="test.employee" scope="session" />

This will create the Employee object and will store it in Person, if the emp object is already not in session scope.
