Hi Amol, I am trying to do the exact same thing. It works for two workers, but fails as soon as I add one worker.
Can you please try these alternatives, and let me know if it works for you? worker.loadbalancer.balanced_workers=tomcat1,tomcat2 worker.loadbalancer.balanced_workers=tomcat1,tomcat3 worker.loadbalancer.balanced_workers=tomcat2,tomcat3 For me, as long as I have two workers, it works. It would be interesting if its the same for you? I also came across these links which I am reviewing. It may help you. http://thought-bytes.blogspot.com/2007/03/how-to-load-balance-tomcat-55-with.html http://www.quadbase.com/eres/manual/6_4_Clustering.html http://www.zulutown.com/blog/2009/02/16/java-ee-load-balancing-with-tomcat-and-apache/ Last question, do you have SSL enabled?
