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
2008-04-21 13:05:35,039 (WebPortalLogger.java:44) - Cluster Member is
