jk2.properties
The examples below are working when the Web Server is configured according the examples described in the configweb file.
using normal socket
There is no need to use the jkjni logic to use normal socket, so that just for Fun.
    # list of needed handlers.
    handler.list=apr,channelSocket,request

    # Override the default port for the channelSocket
    channelSocket.port=8019

    # Dynamic library
    apr.NativeSo=/home1/jakarta/jakarta-tomcat-connectors/jk/build/jk2/apache2/jkjni.so
using AF_UNIX socket
Create and listen on a AF_UNIX socket. The location of the socket must be the same in the Web Server configuration file.
    # list of needed handlers.
    handler.list=apr,channelUnix,request

    # Location of the socket.
    channelUnix.file=${jkHome}/work/jk2.socket

    # Dynamic library
    jtc=/home1/jakarta/jakarta-tomcat-connectors
    apr.NativeSo=${jtc}/jk/build/jk2/apache2/jkjni.so
using user defined class for communication
It is possible to have a user defined class for the communication. Here we have used the ChannelUn as example.
    # Define our own handler.
    class.mychannel=org.apache.jk.common.ChannelUn
    # list of needed handlers.
    handler.list=apr,mychannel,request

    # Location of the socket.
    channelUnix.file=${jkHome}/work/jk2.socket

    # Dynamic library
    jtc=/home1/jakarta/jakarta-tomcat-connectors
    apr.NativeSo=${jtc}/jk/build/jk2/apache2/jkjni.so
using jni channel class for communication
Here we have the minimum configuration needed for the jni communication.
    # list of needed handlers.
    handler.list=apr,request,channelJni

    # Dynamic library needs to be defined only if Tomcat is used
    # out of process
    jtc=/home1/jakarta/jakarta-tomcat-connectors
    apr.NativeSo=${jtc}/jk/build/jk2/apache2/jkjni.so
    # Or you can use the mod_jk2 directly
    apr.jniModeSo=/opt/apache2/modules/mod_jk2.so

    # If you wish to start the Tomcat from inside web server then
    # you don't need any above directive. Here is shown the default
    # value for the apr that you can ommit
    apr.jniModeSo=inprocess
