Hi
Sorry for delay and Thx for the reply

something?
Yes I have 2 TOMCAT individual running on same Windows2000
Machine sharing the same JVM with Startup / Shutdown Ports,but not embedded.
Would this setup be not configurable to be cluster ...?
>>You need some type of load balancer out in front of the two instances

To test clustering setup , do i need a Load balancer ...?

I have the cluster setup as said in the
"http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html";
And since some body on this form replied
"deploy/undeploy your apps only to one server, and the cluster will
distribute the deployments/undeploy across the entire cluster".
with <distributable/> in web.xml
The O/p of these 2 tomcats is as given below

What are you using to split traffic between these two instances? It does
not appear that you have a cluster. It looks like you have two separate
Tomcat instances that have no relationship to one another. I think
that's why everyone is so confused.
I'm certainly confused as to why you would run two Tomcats on the same

Probably, but these two Tomcat instances won't just magically share
traffic with each other. You need some type of load balancer out in
front of the two instances to make the cluster useful.
You continually say "it is not working" but you never describe what is
happening. I can tell you that you will receive no help from this forum
if you continue to ask the same question and never provide any useful
information.
How does it /not/ work? Are any requests handled? Is only one of the
Tomcat instances handling any traffic? Are they not properly sharing
session information? Unbalanced load? /What/ is not working?
