The common solution is to use mod_jk and apache, this is well documented in the wiki: http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss I suggest to use the sticky-session model, it prevents you from some trouble (ie singletons that hold state and stuff) and also reduces the need for session replication (a session then is only lost if a cluster node goes down, and only the sessions attached to that node are lost), you have to evaluate if this justifies to replicate every session. A hardware loadbalancer is always a pretty neat option, we use both (hardware lb to some apaches, apaches to tomcat, all session-sticky) Regards, Martin View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3920372#3920372 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3920372 ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
