Nothing special at the moment.
At the moment we are running two jboss instances with the same
functionality and a quite simple load-balancing that is running in front
of them. The main problem we are working on is how to synchronize these
two servers to avoid concurrent modifications of user-data and to ensure
that each instance is processing up-to-date data. Unfortunately there
are several pitfalls such as separate caches at different
application-layers (the cayenne row- and object-cache at data-layer, a
business-object cache at service-layer), JMS queues between different
layers, etc.
