[java ee programming] Lab 4003: adding a new parameter to the request object
Hi fellows. I hope everyone is great,busy programming with passion!
I'm going through the lab 4003-jsp basics and got a doubt on how to add a new
parameter to the request object as asked for in the task.
The code is:
String username = request.getParameter("username");
if(username != null && username.length>0)
then it forwards to another jsp
this will display name,hobby...but the question is how to add a new string type
parameter to the request,whose value will be displayed by the middle(includes
the response.jsp) along with username,hobby,etc.
I've tried some sample codes,all unssuccesful.
Thanks in advance,
VB

The 2nd part of the instructionsThe index.jsp forwards the request
to another JSP file called middle.jsp. Before forwarding, it should
add another String type parameter called myparameter with value
"Passion!" to the request object. The middle.jsp then includes the
response.jsp. The response.jsp should display the value of the
myparameter along with name and hobby.
In the index.jsp I have the following : name, hobby and birthplace.
<%
String username = request.getParameter("username");
if ( username != null && username.length() > 0 )
{
%>
<%-- this is my forward statement--%>
<%
Once I click submit on the page I get the follwing :
exception HTTP STATUS 500
org.apache.jasper.JasperException: PWC6033: Unable to compile class
for JSP
PWC6197: An error occurred at line: 28 in the jsp file: /response.jsp

PWC6199: Generated servlet error:
Note: string:///middle_jsp.java from uses unchecked or unsafe

It looks as I have to pass the three parms to the middle.jsp is this
correct?
It works on the include but not on the forward

[java ee programming] Lab 4003 - homework - just one question
Hi Colleagues, I have made homework and it works good. According to homework requirements index.jsp forwards request to middle.jsp as follow: Just for test I have used for a moment For me more natural is to use this construction because I understand whole process as follow: Index.jsp forwards myparameter to response.jsp and finally middle.jsp using <%...@include file="response.jsp" %> includes response.jsp and displays all data of respomnse.jsp. Should I use above construction in future or maybe the construction of homework is more proper. Please advice. Best regards, Rafał Laczek Reżyser MUMII powraca z nowym widowiskowym G.I.

[java ee programming] LAB 4003 add parameter question
Hi everyone, The homework tells us to add parameter to the request object in index.jsp before forwarding to middle.jsp. I added the parameter using the request.setAttribute() function and got the desired result. Is this okay? Or do I have to use jsp:param to add the parameter? But then jsp:param can be used only while forwarding and not before forwarding which the homework asks. Any suggestions would be appreciated.
