Ok, I see, I think I get it. :D You've got A and B. A is the primary and it is offloading some processing to B through your JRun cluster. In this case, you don't need a hardware load balancer, as your site is on one real server.
Right now, server B doesn't have/need/use an HTTP server. Run a netstat -n and you'll only see connections to server A and maybe your database or other external processes. All of B's HTTP traffic is going through A. So, you want to know if server A fails, how can you redirect to server B. From what I remember, and I haven't had to fool with it for about a year, you can make a JRun cluster to share sessions but not offload processing to each other. Your web content will be stored on both servers and they will probably both have web servers on them (unless you have a separate web server connecting to a remote JRun for .cfm processing, which could also be load balanced). In this situation, both servers, A and B, are facing the public. This way, they're both visible to your LB, which will run health checks, etc. Continue the cluster and session sharing, but have A no longer offload processing to B.
