Passing custom Session variables around the spring controllers

and my controllers have the session variable with the getters and setters

What exactly the problem you are facing? is the session not set when you try to use in the controller?
have you debugged the code to see whether the session setter of the controller is executed when you run the application?

store the Session bean in the http session, that way it can be accessed from any controller

>  And it gets instantiated after the user logs in.

That contradicts what is in your servlet.xml, which shows you create a single instance at startup.

for poc ur p0c ... check that !! ur changeing o replace with 0 compare to other def !! i found that !!

HttpSession session = request.getSession();
session.setAttribute("UserName", "Sathish");

or
session.setAttribute("userName", urserviceMethod.getDescription());

 urserviceMethod.getDescription() like u can get from DB....

if u set like this means  u can get userNmae anywhere (JSp also u can get )
request.getSession().getAttribute("UserName");

Hi

I used request.getSession().setAttribute("userSession", session);

But after a few minutes the session becomes null, how long is a session active, in other words, when does it get expired.

Thanks.

The session will expire only when ur set the session is invalidated otherwise it wont.....

i think u set the session value again... that value is null so that only it return null....

if ur logout means the session will expire also !!

no i didnt do anything of such sort, it works fine for a while but after say 10 min, it throws the error
when i debug then, i see the session variable is null

Session session = (Session) WebUtils.getSessionAttribute(request, "userSession");

you still haven't posted where you actually add it to the session

At the time of log in and if the login is correct, i create a new custom Session variable and set it in the request session.

 Session session = new Session();
            session.setLoginCredentials(credentials);
            request.getSession().setAttribute("userSession", session);

sounds like your session is expiring.

I am only initiating in the login controller and am not setting it to null anywhere, how does it expire

the container typically times it out after a period

is it configurable, if not how many minutes it keeps it active

Thank you, i am using Tomcat and it is set to 30 min by default
