You should be able to cluster Tomcat without using multicast by having a static members list with TCP pings to check the cluster nodes. You could of course use exported resources to create the static members list.
Not sure about Glassfish but I'd expect it to be possible to do something similar as Weblogic allows the use of unicast instead of multicast for static clusters. - Keith On 29 Apr 2013 05:43, "Shiva Narayanaswamy" <shiva.narayanasw...@gmail.com> wrote: > Thanks for your replies. > > mco is the solution I like.
