JK usage:
-------------
1) Adjust the workers configuration file for apache httpd2
   see /etc/apache2/extra/jk.worker.properties

2) Adjust the global jk section file, if necessary
   see /etc/apache2/extra/jk.global.conf

3) Adjust the jk commons config file, if necessary
   see /etc/apache2/extra/jk.common.conf

4) Add the following line to your /etc/apache2/httpd.conf:
   Include conf/extra/jk.global.conf

5) Include the commons config into the appropriate virtual host section of
   your /etc/apache2/httpd.conf:
   Include conf/extra/jk.common.conf
	
6) Add mount points (aka redirect instructions to tomcat) in the appropriate 
   virtual host sections like:
   <Location /examples/>
       JkMount worker1
   </Location>

NOTE: We recommend not to run tomcat as an apache in-process application,
      since that may give you a lot of headaches and unflexibility.
      However, if you want to use it, just keep in mind the location of
      the Jk JNI library:
      @CLIENT_BASEDIR@/apache2/modules/jk_jnicb.so
