usebean query

Hi all,

I have a doubt on page 416 (or 356) of hfsj. It is given that the third code snippet works fine. But how can it work when the person attribute is not in the page scope(it is in the request scope).It should throw the same error as the first one.

And is it not necessary to have a class in the useBean tag(or is the bean using the instance of employee created by the servlet itself?)

My understanding of usebean is: usebean is used to get the object which is stored in the attribute and get and set properties are used to set the properties in the object corresponding to the usebean.Please correct me if i am wrong.

Regards,
Yeshwanth
