Specifically, this section: " NOTE: Use this [above, simple] configuration when you need very quick a test cluster with at your developer machine. You can change the default attributes from cluster sub elements. Use following cluster attribute prefixes sender., receiver., service., manager., valve. and listener..

Clustering is different for every application server. If you are going to stay with Tomcat 5.5 (no longer actively developed... you might want to upgrade to Tomcat 7.0), then this is the howto: http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html >> What does your code look like that tried to get the session? > > i tried use request.getSession() and request.getSession(true) but with > the same result getSession(true) should never return null.

Good. If you aren't using distributable sessions, then the sessions are unlikely to be available on all cluster members. In that case, you must use sticky sessions. > And yes, every page come with new session id. So, if you're on a page with one session id (let's call is SID_A) and then click on a link that points to http://host/webapp;jsessionid=SID_A, you end up on a page where all the links have SID_B encoded into their links? What happens if you run the cluster with only a single member? You will need to provide configuration information for whatever you are using to do your cluster member choosing: a load-balancer or web server like Apache httpd.
