Re: HttpSession - problem

--
--
[ Picked text/plain from multipart/alternative ]





What WAS level?

When I read the description on how it should work, I see submit 'login.
class' creates a new 'session'.  But in the problem description, after
submitting 'login.class', having a new 'session' is considered abnormal.
Can you clarify.

I've seen a similar authentication flow, but instead of a .forward( )  to
the controller.class a SendRedirect was used, that may be one change you
can try to see if it helps.

Does your stdout/stderr show any evidence of errors, I'm suspecting there
may be an error that mentions 'anonymous' as part of the text.

I hope one can help me with this tricky problem:

I have a WebApp which is running under 'Basic Authentication' and has
following objects:
- index.html
- login.class
- controller.class
- databean.class
- jsp1.jsp
- jsp2.jsp
- error.jsp

it should work as follows:
- index launched
- form submit 'login.class' with 2 parms: parm1, parm2
(value=controller.class)
        - basic authentication is activated
           (userid/password is asked and entered)
        - create new 'session'
        - gets default uservalues from AS400
        - stores default uservalues in session
        - redirects to parm2 (controller.class)
                ==> getServletConfig().
                       getServletContext().
                      getRequestDispatcher(controller.class).
                       forward(req, res);
- controller class loaded
        - retrieves 'sessionvalues'
        - detects which jsp to load
        - loads jsp1.jsp
- jsp1.jsp loaded
        - values changed
        - loads controller.class
- controller class activated
        - retrieves 'sessionvalues'
        - detects which jsp to load
        - updates databean.class
        - loads jsp2.jsp
etc...

The controller's work is retrieving sessionvalues, updates beans, launch
jsp's.  When session-timeout occurs, error.jsp is returned.

Problemdescription:
When I submit the 'login.class' with parm2=controller.class, the 'session'
is considdered as 'new'???
I use the following to retrieve the sessioninfo:
   session = req.getSession(true);
   id = session.getId();
   if (session.isNew())

In normal situations, the session should get a 'false' on 'if
(session.isNew())' but it always returns 'true'.  However, when I check the
sessionid, it is always the same!!!

When I change parm2 in 'jsp1.jsp', I do not get this strange behaviour...
The jsp is loaded, this form submits the controller which detects the
correct session (session.isNew() = false) and loads jsp2.jsp.



Here's an extract of debugginginfo printerd to 'std_out'
where you can see that sessionid doesn't change...
