To me it's not quite clear what you are doing exacly. I see three option to use an externl loadbalancer. Which one is the one you use ?
- use mod_jk with sticky sessions. - Setup two apaches with a mod_jk. - Setup loadbalancing for mod_jk. - Setup two tomcats with a unique jvmRoute. LB / \ / \ A1 A2 |\ /| | \ / | | x | | / \ | |/ \| T1 T2 Although the last mails from Bill Barker indicate that current implementation of mod_jk doesn't balance the load equally, this scenario should work for you, as the external load balancer does this already. The Loadbalancer in mod_jk is just used to route the requests to the correct tomcat. - use session replication. In this scenario each instance of tomcat has a copy of the session data, so it doesn't matter which receives the request. In this case you can omit apache and mod_jk and use tomcat native. LB / \ / \ A1 A2 | | | | T1---T2 - use a load balancer that supports sticky sessions (url and cookie based sessions) In this case you can treat each tomcat as a stand alone server.
