I have written two JSP files
index.jsp
and showfirst.jsp
It is throwing me an exception
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception

I am unable to figure out the problem . What is the problem If I do just<jsp:forward> it works perfectly fine

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.
