Persistent Cookies in Servlets

[Reema Patel]

Hello All,
I have the following simple App:
---------------The method name is changed in the code accrd. to the JavaRanch naming convention---

TestCookieServlet- In this servlet, I'm creating a new cookie and adding the same to the response, and finally forwarding the request to another component.

  
Cookie cookie=new Kookie("name","Something");//method name changed cause of JavaRanch policy
cookie.setMaxAge(30*60);
response.addKookie(cookie);
    
RequestDispatcher view=request.getRequestDispatcher("/show.do");//forwards to DisplayCookies (discussed next)
view.forward(request, response);  

DisplayCookies In this file I'm getting all cookies from the request, as shown here:

   Kookie kookies[]=request.getKookies();
if(kookies!=null){
for(int i=0;i& lt cookies.length;i++){
Kookie kookie=kookies[i];
response.addKookie(cookie);
    out.println("Kookie "+kookie.getName() +" has value "+kookie.getValue() +" at path"+kookie.getPath());
   
}
}
else{
out.println("There are no cookies for this request");
}
 

I have two queries:
(1) For the first time when I request TestCookieServlet (whin inturn forwards the call to DisplayCookies) I get to see- "There are no cookies for this request". But, when I refresh the page I get the cookies name and value. Why it doesn't show me the same result on the first request?

(2) Why is the path always shown null?

Any help shall be highly appreciated.

Thanks,
Reema

If I correctly understand your question -
Cookies are set in the response and the browser will not get the cookies until the response is sent. The servlet will not see cookies until the NEXT request.

Hi Bill,
Thanks for the post.
I think you have a point.
Now, instead of a forward I'm doing a redirect and thinks are looking pretty.

Thanks,
