jules Sep 24, 2002 1:32 PM (in response to dtlseepz)Do you mean that you wish to preserve session contents across restarts of JBoss ? or something different ?

dtlseepz Sep 25, 2002 1:46 AM (in response to dtlseepz)Hi Jules,
Thanx for ur concern.. Actually I want the session to
be active accross all the servlets in my webapp...
I just want the session info to be available to me when I move from one servlet to another...

jules Sep 25, 2002 4:55 AM (in response to dtlseepz)I don't whether me reply made it - so :
Sessions are scoped within a context/webapp.
To declare that all your servlets shuold be able to see the same session package the, all in the same war/webapp.

dtlseepz Sep 25, 2002 10:41 AM (in response to dtlseepz)Hi Jules,
Yeah, all the servlets are in the same .war file.
See I just want my session to remain when I move from
one servlet to another within same webapp.
These things are pretty simple in WebLogic, Tomcat etc. I don't know what's the problem here... Is there any setting to be done in jetty or some file in jboss to enable the session....??
Thanx again,

jules Sep 25, 2002 11:46 AM (in response to dtlseepz)It should work.
Are you sure it doesn't.
Have you got something that works in Tomcat and doesn't in Jetty ?
Please describe the exact steps to replicate your problem.

dtlseepz Oct 1, 2002 6:55 AM (in response to dtlseepz)Hi Jules,
The following is the explanation of my code.
1) Browser displays the login.jsp which has accepts User Id & Password.
2) On click of Submit, the control goes to the LoginControllerServlet?action=validate which validates the user id & password entered by the user. Currently, in this code, the User is hardcoded as "ABC".
3) The LoginControllerServlet forward the controls to the ManageForumServlet?action=listAllForums which in turn displays the DisplayForums.jsp which shows some hyperlinked names. i.e.
JBoss 3.0.2
4) On click of hyperlink, the control again goes to the ManageForumServlet?action=listAllTopics which displays the DisplayTopics.jsp
The session works fine till point 3. But when we click on hyperlink (i.e executing step 4), the session object appears as null.
The same code works fine under Tomcat 3.2.4.
Please help. Thanks for your co-operation.
The following is my code.

roozbehghaffari Feb 15, 2003 11:36 PM (in response to dtlseepz)Hi,
Did you come up with a solution? I have the same problem. This is ridiculous. This is one of most basic features a servlet container should have.
