I have an application which does most of it's work in the servlet engine and only occasionaly needs to access EJBs. We think that we need a configuration where we have multiple boxes running Tomcat all accessing a single box with the EJBs on it. Everything I have seen so far around clusters with JBoss has some sort of load balancing in front of some number of instances of JBoss with integrated Tomcat (or whatever). Is it possible to have only one or the other on a box? Does it even make sense to want to?
