Whats the best choice to reduce downtime while deploying an updated version of some ejb components?

Is it possible to update parts of an ejb based application without losing session states?

Are there any ressources available concerning this topic?
For example: how to lock sessions for a clean application shutdown before the new one gots redeployed?

I just know that i need the possibility to update my app as fast as possible, but i really got no idea how to reach this goal. (Or should i say: i just got no idea about available, proven possibilities)

Another idea: When there is a clustered environment - might it be possible to route all clients to server b while deploying the new ear on server a?

as always: thx for your help
