Subject Re: apache + mod_jk + two tomcat instance configuration
Date Sun, 01 Jun 2008 04:40:11 GMT

Jiansen... you actually have stuff configure that you dont need
like

worker.worker001.lbfactor=1

you not load balancing

and

DocumentRoot /usr/servers/apache-tomcat-6.0.16/webapps/www.domain1.com

you dont have to help JK find the webapps

I found an article for you

http://laxmangunjikar.wordpress.com/2008/01/07/multiple-instances-of-tomcat-with-apache/

Hope it helps
