Hi Andy,
The servlet API does use cookies for sessions. Keep in mind that an HTTP "session"
isn't really a session at all because there's no true stateful connection in place
over HTTP. Although your web/app server will remember a session, a browser/client
will not. You can choose to not utilize cookies, and maintain a session, by always
passing your session ID around within your program. See Priscilla's email.

Becky,
Thanks for your reply. My browser didn't accept cookies. I enabled them.
Please correct me if I am wrong! I was under the impression that Session Management
using Servlets API does not require the use of cookies. I thought Session Tracking
using URL Rewriting, Using Cookies and Using Hidden Form Fields were old methods of
session tracking and servlet API was designed so that one can do session management
without having to use any of these. Is that true?
If yes, why would I require to enable cookies in order to run my code?
Thanks for the help!

Does your browser accept cookies? If not, turn on the acceptance of cookies b/c the
session object makes use of them to "remember" itself.
You have to first retrieve the session, then retrieve the object from it. Did you do
that?
I would assume this is your code:
setting: HttpSession sessionName = requst.getSession();
sessionName.setAttribute("objectName", someObject);
getting: HttpSession sessionName = request.getSession();
someObject objectName = (someObject) sessionName.getAttribute("objectName");
If not, fix your code.
It's possible to maintain a session w/out cookies, but you'll have to look that up
yourself. :)

Frans,
Thanks for your reply.
It is in the same servlet context. Are you saying that it is in the same directory?
All my files are in the same directory. However, I do have my classes and the web.xml
file stored in the WEB-INF directory within my main application directory.
Any suggestions or ideas that I could possibly try?
Thanks!
--Andy.

Is the page to which you are redirecting a servlet inside the same ServletContext. A
session can only be used from within the same ServletContext, i.e. the web application
directory.
