what is person here if called directly through hyperlink.


request.setAttribute("person",person);



Here you set person as request attribute , hence <jsp:forward> would work fine as it belongs to same request.

<jsp:forward> uses the same request object and pass it to the forwarded page and it all happens in server , whereas hyperlink is a new request which is originated from client.
