tomcat cluster for stateless web application
I've noticed that in the documentation, it says a lot about session replication.
I wonder what can be omitted in the configurations for a stateless
java webapp setup (without any sessions),
to hopefully get a simpler configuration or even gain more efficiency,
bypassing the replication altogether ?

Hi Albert,
only you have to setup is loadbalancer in front of your tomcat servers.
That is all.

Formal "clustering" (in Tomcat) is only useful for session
replication. If you don't need session replication, all you need is a
load balancer, and you don't really even need to configure it other
than to say "balance these backend servers in some way (rr,
load-based, request-based, etc.).
If you are using Apache httpd with mod_jk, then you just need an "lb"
worker with balance_workers set to all the backend workers, and
disable sticky sessions (because the default is to use sticky
sessions, but you aren't creating sessions, anyway, right?).

Well, start by not configuring the cluster. That should be enough.
