Cookie Deletion

[Sameer]

Hi all,

I'm trying to delete a cookie using this :

........
<%
String name1 = request.getParameter("cookieno");
Cookie delCookie = new Cookie(name1,null);
delCookie.setMaxAge(0);
response.addCookie(delCookie);
%>
 ...........

where name1 is the name of the cookie, this piece of code runs fine on Java
Web Server, but when I use this on a Tomcat Server, I get a null pointer
exception when I try to retrieve the cookies after I have executed the above
code,
any help?...or suggestions on where im going wrong

thanks in anticipation,
Sameer
