Hi... first, although it is not really relevant to your question, you do not
need to explicitly import the javax.servlet.http and javax.servlet packages
into a jsp; they are automatically included. At first glance your code
looks OK, but I have never attempted to use the "setDomain" and "setPath"
methods when writing and retrieving cookies. I suspect that your problem
lies there. I would suggest that you try to take the SIMPLEST approach first
and see if that works. That is, just write the cookie and attempt to read it
back WITHOUT doing the "setDomain" and "setPath" stuff. If that works, then
you know where your problem lies.

Hi everyone,
I am trying to write and issue a cookie on one page and then retrieving it
in another page but its not working can anyone help?
I am using the following code to write:
<HTML>
<HEAD><TITLE> issue cookie </TITLE>
<BODY>
<%@ page import="java.util.*"%>
<%@ page import="javax.servlet.http.*"%>
<%@ page import="javax.servlet.*"%>
<%@ page import="java.io.*"%>
<%
Cookie c = new Cookie ("firstname","mazin");
c.setMaxAge(3600);
c.setDomain(".scitse.wlv.ac.uk:7777");
c.setPath("/");
response.addCookie(c);
response.setContentType("text/html");
%>
</BODY>
</HTML>
and the following to retrieve:
<HTML>
<HEAD><TITLE> get cookie </TITLE>
<BODY>
<%@ page import="java.util.*"%>
<%@ page import="javax.servlet.http.*"%>
<%@ page import="javax.servlet.*"%>
<%@ page import="java.io.*"%>
<%
Cookie[] cookies = request.getCookies ();
response.setContentType("text/html");
if (cookies!=null){
for (int i=0; i<cookies.length;i++){
Cookie c = cookies[i];
String name = c.getName();
String value = c.getValue();
int version = c.getVersion();
out.println(name + " = " + value);
}
}
%>
</BODY>
