Keeping Sessions between Jboss AS 7 restarts/deployments

Question

We use JBOSS 7 AS and I wondered always if it can be configured so, that the sessions are not lost after restarts or deployments. Are there any possibilities for that, supposing in the session there is no non-serializable data stored ?

Answer 1

Restarts : If you setup a cluster with session replication then your sessions should be served by another jboss instance if the instance you are connected to fails.

Deployments : Deployments generally take a long time (at least more than a few minutes) ; I dont see the point in maintaining session state across deployments.
