Why mod_jk ?

[Andrew Ralph Feller, afelle1]

For those who need to support Java applications along with PHP / Perl
applications, they could host both from the same machine by having Apache
httpd front-end Apache Tomcat.  There is a another reason why some people
use mod_jk + Tomcat: inexperience in managing Tomcat.  When I was starting
out, I hated working with keystores as it wasn¹t nearly as straight forward
as Apache httpd¹s mod_ssl configuration.  Once I found how to setup the
Apache Portable Runtime in Tomcat, then I felt comfortable not having Tomcat
front-ended as the APR configuration is extremely similar to mod_ssl.

On a tangential note, there is an alternative to mod_jk called
mod_proxy_ajp, which comes with Apache httpd 2.2 and works in a similar
manner.
