Hi all.
using session tracking technique :
HttpSession session = request.getSession( ); // inside a servlet
session.setAttribute(" ", " "); // inside a JSP
how to make the cookie a *persistent cookie* ?
not disappear at the session end when closing the browser ?
another thing please:
As I know, if the client enabling or disabling the cookies inside his browser, I should not care, the container will take care.
In my application, I have used the session tracking and I have enabled the cookiesand every thing fine, but when disabling them, a NullPointerException is thorwn because the cart object is not created).
So, how to know of the client disabling the cookies ? and if so, what should I do ?

take a look at the API docs, there's a class Cookie you will want to learn more about.
 
It is sorta covered in the JavaRanch Style Guide.
