I'm not understand your question clearly.
What you men by jvmRoute?
The loadbalancing is only for EJB (rmi) calls, HTTP requests are not load balanced.
This is normally done by apache in front of JBoss
Imagine that i have one Apache httpd configuration to make load balancing for 2 JBOSSs in 2 different machines.
Now, if i want to configure 2 workers (on Apache) to access the same JBoss instance do i need 2 jvmRoutes ( configured on Jboss server.xml) or can i configure that 2 workers to access same jvmRoute?
I think i found the answer: We can use attribute route in those two workers to point to same jvmRoute.
