This document describes the configuration files used by JK on the
web server side for the 'impatient':
workers.properties is a mandatory file used by the web server and which
is the same for all JK implementations (mod_jk for the Apache HTTP Server,
ISAPI for Microsoft IIS, NSAPI for the iPlanet Web Server).
web server add-ons to be set on the web server side.
We'll give here minimum servers configuration and an example workers.properties
to be able to install and check quickly your configuration.
Here is a minimum workers.properties, using just ajp13 to connect your web server
to the Tomcat engine, complete documentation is available in Workers HowTo.
# Define 1 real worker using ajp13
# Set properties for worker1 (ajp13)
Here is some very basic information about Apache configuration, a
more complete HowTo for Apache is available.
You should first have mod_jk.so (unix) or mod_jk.dll (Windows) installed
in your Apache module directory (see your Apache documentation to locate it).
Usual locations for modules directory on Unix:
Usual locations for modules directory on Windows:
- C:\Program Files\Apache Group\Apache\modules\
- C:\Program Files\Apache Group\Apache2\modules\
You'll find a link to prebuilt binaries
Here is the minimum which should be set in httpd.conf directly or
included from another file:
Usual locations for configuration directory on Unix:
Usual locations for configuration directory on Windows:
- C:\Program Files\Apache Group\Apache\conf\
- C:\Program Files\Apache Group\Apache2\conf\
# Load mod_jk module
# Update this path to match your modules location
LoadModule jk_module modules/mod_jk.so
# Declare the module for <IfModule directive> (remove this line for Apache 2.x)
# Where to find workers.properties
# Update this path to match your conf directory location (put workers.properties next to httpd.conf)
# Where to put jk shared memory
# Update this path to match your local state directory or logs directory
# Where to put jk logs
# Update this path to match your logs directory location (put mod_jk.log next to access_log)
# Set the jk log level [debug/error/info]
# Select the timestamp log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# Send everything for context /examples to worker named worker1 (ajp13)
JkMount /examples/* worker1
A separate HowTo for the Microsoft IIS web server is available.

A separate HowTo for the iPlanet Web Server is available.
