Hello,
I am using the jk1.2.15 connector to connect the apache 2.0.55 webserver to
tomcat 5.5.15 on a windows 2003 server.
However, I am not getting any luck with the connector.
I googled for hours on the internet, but nothing that matches.
I even found contradictory information.
In the docs it states that the workers should not be defined in the
workers.list when you are using load balancing, but in the examples I found
on the internet, they were defined in the workers.list (and yes I tried it
but it just gives another error message).
I keep on getting the message:
Could not find a worker for worker name=tomcat1.
--------------------------------------------------
In my workers.properties, I have defined:
--------------------------------------------------
workers.tomcat_home=d:/java/apache-tomcat-5.5.15
workers.java_home=C:/Program Files/Java/jdk1.5.0_06
ps=/
# define special the workers load balancer and jkstatus worker
worker.list=wlb,jkstatus
# Defining a worker named tomcat1 and of type ajp13
worker.tomcat1.type=ajp13
worker.tomcat1.host=ntbrawebdv11.braine.ucb
worker.tomcat1.port=8009
# The higher lbfactor, the more priority to do work.
worker.tomcat1.lbfactor=2
#
# Defining a load balancer
#
worker.wlb.type=lb
# A list of all the workers that are load balanced.
worker.wlb.balance_workers=tomcat1
# use sticky sessions
worker.wlb.sticky_session=True
# Give an error if a worker is in error state. The connection will not be
switched to the other workers.
worker.wlb.sticky_session_force=True
# Use the number of requests to perform the load balancing.
worker.wlb.method=Request
#
# Define status worker
#
worker.jkstatus.type=status
----------------------------------------------------------------------------
-
In my tomcat.conf file which I include at the bottom of the httpd.conf file
I have:
----------------------------------------------------------------------------
-
# Block any access to WEB-INF directories
<Location "/*/WEB-INF/*">
AllowOverride None
deny from all

JkMount /*/viewdocument tomcat1
# Any dqlbatch servlet
JkMount /*/dqlbatch tomcat1
# Any folderlisting servlet
JkMount /*/folderlisting tomcat1
----------------------------------------------------------------------------
-
And in the server.xml file of my tomcat, I have defined the http connector:
----------------------------------------------------------------------------
-
<Connector port="8009"
enableLookups="false" redirectPort="8443" protocol="AJP/1.3"
/>
and on the engine tag I have defined the jvmRoute attribute:
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
When I put the jk connector in debug mode, I get something like this:

If I change the config, and add the worker in the workers.list, then it just
tells me that it can not initialize the tomcat1 worker.
Can anyone help me one this, since I'm out of ideas. I tried to telenet to
port 8009, and something was acctually listening, so the jk connector should
be there.
The good old jk2 (which is no longer supported) works, but I'd really like
to use the supported version that comes with tomcat.
