[ Picked text/plain from multipart/alternative ]
It is in the Websphere Test Environment.
I am just migrating code from VAJ3.5 to VAJ4.
I had problems because we used sendRedirect instead of forward.
I have changed the code and used forward to call JSPs from servlets,
and servlets from servlets, etc ...
When I forward from the servlet to the JSP it is ok, I can
find the information in the session. When I call another servlet
(from an hyperlink, or typing the url), when I enter in the second
servlet code, the session id is different.
We have implemented an MVC model based on an article found in VADD.
Each servlet derives from a base class, and in this base class we
get the information from the session.
The code is _session = request.getSession(true);
Why in some case it creates a new session and in others no?

Gilles -
What container are you running this in? Depending on the container,
there may be certain setup requirements where you have to tell the
container that you want to use sessions, what the session timeout is,
etc. How are you identifying sessions? In other words, how does the
container match an interaction to a stored session? Are you using
cookies or URL rewriting or some other means?
If your code is working, I suspect the session support is not properly
set up for the container. However, without knowing what servlet engine
you're using, it's difficult to go further.
