How to Build the latest mod_jk RPM

mod_jk is an Apache module used to connect the Tomcat servlet container with web servers such as Apache. It has come increasingly difficult to find a an apache2-mod_jk-1.2.37-4.1.src.rpm or apache2-mod_jk-1.2.37-4.1.rpm as some of the links are now dead.  However, after tracking down a copy of the apache2-mod_jk-1.2.37-4.1.src.rpm, a modification or two to the .spec file along with the official .tar.gz file will allow for a successful build of a mod_jk RPM for use on CentOS 6 with Apache 2.2.

Using rpmrebuild, it was plain that the official build used this source, apache2-mod_jk-1.2.37-4.1.src.rpm.
