I'm going to say that it's possible to do it with minimal interruption, but I'm not sure about no interruption. If you configure multiple mid-tier servers behind a load balancer, if one of them goes down then the load balancer would re-point them....which would force them to log back in because their session is invalid on the other server....but I did look into Tomcat clustering that did session sharing, but didn't get far enough down that road to actually test anything.

That is, a cluster of Midtier servers that behave as a virtual single server so that if one server fails the other picks up the load without the end users noticing?
