Did you add a "load blancer worker" to your workers.properties? Below is what I use to perform load balancing over two Tomcat servers.
I have a similar scenario: Apache in front of two (or more Tomcats). Apache forwards the requests using mod_jk. My client is sending SOAP requests using Axis2. worker.list= wlb, jkwatch ############################################################################## # Defining a load balancer worker ############################################################################## worker.wlb.type=lb worker.wlb.balance_workers=tomcatserver1, tomcatserver2 worker.wlb.max_reply_timeouts=3 # worker.wlb.retries=2 # worker.wlb.retry_interval=100 # worker.wlb.sticky_session=True # worker.wlb.sticky_session_force=False # worker.wlb.method=Request # worker.wlb.lock=Optimistic ############################################################################## # Defining the status workers ############################################################################## # A read-only status worker worker.jkwatch.type=status worker.jkwatch.read_only=True worker.jkwatch.mount=/private/admin/watch/jk # A managing status worker # worker.jkmanage.type=status # worker.jkmanage.mount=/private/admin/manage/jk ############################################################################## ## Balanced Workers (Tomcat Workers) ############################################################################## ############################################################################## # Tomcat Worker (tomcatserver1) ############################################################################## worker.tomcatserver1.type=ajp13 worker.tomcatserver1.host=localhost worker.tomcatserver1.port=8009 worker.tomcatserver1.lbfactor=1 # Connection pool timeout is set in seconds.

However, when I put Apache infront of one my tomcat servers and set it up to forward http requests to the tomcat server it doesn't get any requests. I am using the mod_jk to achieve the forwarding. I have tested other types of http forwarding, and they are all ok. So I am confident, I have my workers.properties, ajp ports etc set up ok. I am getting no error messages in my mod_jk logfile. I wonder can mod_jk only forward only certain types of http requests? Any ideas?
