TOMCAT CLUSTERING ONJAVA

Hi

Reffered to URL 
"http://www.onjava.com/pub/a/onjava/2004/04/14/clustering.html?page=1"

The Load balancing  using Cluster Techique for 3+ TC's,

The site has also provided  a SAMPLE Code "tomcatclustering.zip"

I was wondering if any body on this TOMCAT form has achieved the same on 
TOMCAT5.5.23 version.

Cause  I am getting the ERROR  as below

Hi



 >> Rather than looking at doc that's over four years old

The Main TOMCAT out of 4 numbers, act's a  Load Balancer itself

Which is exciting and simple for  configuration.

 >> http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html

Observed this URL, Does the topic Load Balancers /Using the balance 
webapp say same thing as above ?


I am in deli ma .....:(

with regards
Karthik

Rather than looking at doc that's over four years old (and was sadly out
of date even then), why don't you use the real Tomcat documentation?
