Correct. This is true for pretty much any application server product.
Something has to front-end the cluster to know to re-direct the
request from a failed node to a running node.
As a side note, we also have customers front-ending a cluster using a
hardware load balancer. So your choice is really mod_jk, the glassfish
load-balancing plugin for IIS/Apache/SunWebServer, or a hardware load
balancer.
