Are you saying that you are doing a forward to this page after setting the cookie(s) or something else ?

That means the browser is not sending the other cookie(s) besides the JSESSIONID cookie? Can you explain the request flow you used to test this?

I don't understand why you haven't posted the code, config, and URLs you're using to test this.

The way you're displaying the cookies is correct--if there should be a cookie on that page, it'll display it. Which means in all probability there isn't the cookie there you think there is. Have you confirmed the cookie physically, either by using the browser tools, or checking on the disk? Is the path right? Show us the code.

That's the code for *displaying* the cookies. That's not the only code being run, nor is it the only information necessary (or available) to help diagnose the problem.

David Newton wrote:That's not the only code being run

what else is required please reply ?
the code posted by me is directly taken from "Bruce perry's" book "java servlet and Jsp cookbook" ?
if its wrong then what else is required to display a cookie ?

When you're trying to diagnose a problem, you need everything related to the problem. In addition to displaying an existing cookie, the code that creates the cookie is required. You haven't provided the information about what's in the cookie, like the path information for both the working and non-working cookies. The URL of the page being requested that you're trying to display the cookies from.

We're not in front of your machine--you have to help us to help you.

I think that probably you don't have other cookies. Of course that there are a lot of cookies in your browser, but it must belong to your site. :]
If you are running in localhost, then the cookies must be in the localhost folder.

my browser has two cookies :

first cookie :

second cookie :

the servlet code below is setting and checking cookie :

package myemployee ;
import java.sql.* ;
import java.io.* ;

import javax.servlet.* ;
import javax.servlet.http.* ;
import javax.servlet.http.Cookie; 
import java.lang.String ;
import java.lang.Integer ;
import java.util.* ;

public class registeredcookie extends HttpServlet {
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
Boolean regis=false;

//checking cookies present or not , then setting  cookie
Cookie[] c = request.getCookies();
if(c!=null){
for(int i=0;i<c.length;i++)
 { Cookie c1=c[i];
    if((c1.getName().equals("regcookie"))&&(c1.getValue().equals("qwerty")))
    {regis = true;
    }
 }
}
if(!regis)
{ Cookie reguser = new Cookie("regcookie","qwerty");
   response.addCookie(reguser);
}

//checking cookie is present or not
Cookie[] c5 = request.getCookies();
if(c5!=null){
for(int i=0;i<c5.length;i++)
{Cookie c6=c5[i];
    if((c6.getName().equals("regcookie"))&&(c6.getValue().equals("qwerty")))
    {out.println("--"+c5[i].getName()+"--"+"<BR>");
     out.println("--"+c5[i].getValue()+"--"+"<BR>");break;
    }
}
}

}
}

i want to get the name and value of the "regcookie" and i get it in this servlet page at line 39 and 40 , but not in the jsp page.
in the jsp page i get only the name and value of "JSESSIONID" not the "regcookie".

how can i retrieve the value of regcookie .using scriptlet it is possible but i have no luck in EL .
please help.
