JSF - javax.faces.STATE_SAVING_METHOD
Posted:

We are having with a JSF application and it's navigation. On occassion the when hitting the next button the application will return to the starting page. It is as if session data has been lost so the application thinks the user is entering the first time. This is a random occurence and happens on IE, Firefox and Opera.
The app is running on glassfish (proxied and load balanced).
We are not sure how to diagnose the issue. Any help would be appreciated.
There is some debate amongst the developers whether javax.faces.STATE_SAVING_METHOD should be set to "client" (the netbeans default setting) or "server". I have suggested it be changed to "server" to see if that solves the problem (an easy change, but the main developer of the application wants to know what "best practice" is before he makes the change).
Another developer thinks the navigation rules in the faces-config.xml should be altered.
Thanks for any feedback.

Everything you say sounds like a misconfiguration of the load balancer to
me. I would try running it outside the load balancer and see if you can
reproduce the problem, then if it still occurs, you could look elsewhere.
In our app, we have multiple forms on the page, and in client state saving
the state is written to the response for each form so our simple pages ended
up being a 2MB download for the client, so we went to server. We never had
any problem losing state with either configuration.
If you can reproduce it reliably only on certain pages, then faces-config
could be the problem, but as I said, I would look at the load balancer first
given your symptoms.

Thanks for the reply.
We have 8 glassfish servers / 2 per load balancer, each server pair handles applications based on type (finance, HR, etc).
This is the only app (out about 30) that is having this issue. It is one the earliest JSF apps this team wrote. We don't think the load balancer is the issue otherwise other apps would be failing.
Regards,
Bryan

The behavior you are observing is indeed consistent with the session
being lost. I would install an HttpSessionListener and track when the
sessionDestroyed() method is called [1].
If this doesn't lead you anywhere, please followup to the list here and
we'll continue to work it.
