Now there's another question: How can I configure mod_cluster to use
round-robin to distribute requests?
Weinan,
mod_cluster has been built around the idea of load-balancing intelligently by communicating load from the server to the load-balancer. Round-robin is far from intelligent :-) and there is no such option.
Look at what options you have for configuring load metrics in AS7
http://docs.jboss.org/mod_cluster/1.1.0/html_single/#LoadMetric (so "requests" might be the best one to actually see it load-balance).
You might also want to try killing the server to see it fail-over to the other instance.
