I would like to use apache to load balance http requests to a cluster of JBoss 
server instances. I think JNDI and EJB clustering will be too expensive for 
this application, so I prefer clustering at the http level. The main reason for 
clustering is to scale memory across several JVMs so I would like to 
instantiate several server instances on one computer.

It is not clear to me from reading the docs how to configure and instantiate 
multiple server instances on the same computer. 

I have been able to get a simple configuration of one JBoss instance to work 
with the apache load balancer. I tried intantiating another instance by copying 
the config directory of that instance and changed the config to reflect the new 
instance. When I tried to start the new server instance, I got a complaint 
about ports already utilized. This leads me to believe that I'm on the wrong 
trac...

Is it necessary to start each instance individually? If so, how is it 
configured? If not, how is it configured? I want to use the fail over 
capabilities of JBoss clustering, so I'm assuming that I'll need all the JBoss 
clustering configuration. It's not clear how the node instances get 
instantiated and how each instance would be differentiated by apache. There 
doesn't appear to be a way to configure the port of each server instance...

I'm using Apache 2.0.53 - JBoss 4.0.1RC2 - mod_jk 1.2.8-apache-2.0.52

Any recommendations or ideas would be greatly appreiated
Thanks in advance
Keith Roberts...
