Have been trying to cluster tomcat over the past few days and just had a couple of questions.
I am using tomcat bundle with jdk-1.6 and openBSD 4.8
1.Can tomcat be clustered for just for development without a load balancer or do I need to use mod_jk?
I have been trying to get them to cluster but have so far been unsuccessful.

keep getting this no members in cluster group error.
mod_jk logs give this error

This is my workers.properties file. i have edited server.xml to include the jvm route of tomcatA and B and include < distributable > context.
LoadModule proxy_module /usr/lib/apache/modules/libproxy.so
LoadModule jk_module /usr/lib/apache/modules/mod_jk.so
JkWorkersFile /var/www/conf/workers.properties
JkLogFile "logs/mod_jk.log"
JkLogLevel error
JkMount /clsuter/* load
This is my httpd.conf file where i have loaded the module and its logging so its successfully starting up just cant find the worker "load" even tho it has been specfifed in the workers.properties.
If anybody could give me some guidance regarding this it would be good thanks.
