Help with Apache plugin for Tomcat

Question

I downloaded jakarta-tomcat-connectors-jk2-src-current.tar.gz from apache.org. I am trying to install this without any progress. The web page http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html gives lots of info on how to install the plug in called JK. I believe the unix section applies to linux as well. Can anyone help me with this? Please copy your message if at all possible to [email protected] Thanks Murthy

I know what mod_jk is, I was just trying to understand your situation.
You have two choices, mod_jk and mod_jk2 with different configurations files.
In both cases, you need 3 parts:
1- apache
2- the mod_jk(2) module (.so) for your apache version (1.3.x or 2.x)
3- tomcat
You obviously have 1 and 3, and probably 2 also.
Config is twofold:
1) In httpd.conf (Apache 2.0) you need:LoadModule jk2_module modules/mod_jk2.so
<IfModule mod_jk2.c>
  JkSet config:file "/path/to/workers2.properties"
</IfModule>
# And for each context:
   <Location "/contextname/*">
      JkUriSet worker ajp13:localhost:8001
   </Location>2) workers2.properties:[logger]
level=WARN
#INFO
#/web_ci/
[config:]
file=/path/to/workers2.properties
debug=0
debugEnv=0
[uriMap:]
info=Maps the requests. Options: debug
debug=0
# Alternate file logger
[logger.file:0]
level=WARN
file=/path/to/logs/jk2.log
# Cache for activity
# Must point to a writeable path
[shm:]
info=Scoreboard. Required for reconfiguration and status with multiprocess servers

debug=0
disabled=0
[workerEnv:]
info=Global server options

debug=99
# Default Native Logger (apache2 or win32 )
# can be overriden to a file logger, useful
# when tracing win32 related issues
logger=logger.file:0
# Communication channel to use
[channel.socket:localhost:8001]
info=Ajp13 forwarding over socket
debug=0
tomcatId=localhost:8001
# Connector as in conf/server.xml
[ajp13:localhost:8001]
channel=channel.socket:localhost:8001
# Tomcat load balancing
[lb:lb]
info=Default load balancer.
debug=0
[status:status]
info=Status worker, displays runtime informations
# Monitor for requests and config http://server:port/jkstatus
[uri:/jkstatus/*]
info=Display status information and checks the config file for changes.
group=status:status3) Finally, you need to set the connector (port number) in server.xml    <!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8001 -->
    <Connector className="org.apache.coyote.tomcat5.CoyoteConnector"
               port="8001" minProcessors="5" maxProcessors="75"
               enableLookups="true" redirectPort="8443"
               acceptCount="10" debug="3" connectionTimeout="2000"
               useURIValidationHack="false"
               protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>This is the setup I use on Win2K, but should work pretty much the same on Linux. I also have a similar setup on Linux, but with mod_jk instead of mod_jk2.
Hope this helps!
