I think the problem is in response.jsp, you are trying to use variable
username but , middle.jsp and response.jsp do not know what is
username.(when we forward the request the new page does not have
access to variables defined in the source page unlike include) So you
have to extract String username from request again either in middle.jsp
or response.jsp.
I hope it works!

I try to do my #3 homwork, I have problem:
For those who knew:
in index.jsp i added
....
<%
String myparameter = "Passion";
String username = request.getParameter("username");
if ( username != null && username.length() > 0 ) {
%>
<jsp:forward page="middle.jsp"/>
<%
....
then I write middle.jsp like this:
<%...@include file="response.jsp" %>
and response.jsp is ok, but after I click Submit in arise page, I have got
this error:
HTTP Status 500 -
