Tomcat 4.0 did not select mod_jk for several reasons.  The most important ones
are at the top:

* MOD_JK (like MOD_JSERV before it) has no clue what a web
  application is.  This forces you to configure many items twice --
  once in the web.xml file and once in the Apache configuration,
  which is a pretty serious imposition on people trying to administer
  the combination.

* While the 2.2 spec was silent in many areas, the 2.3 spec will
  require an Apache+Tomcat combination to obey *all* the requirements
  of the spec (same rules as for any other container).  This means that
  the things in web.xml *must* be respected.  For example, a security
  constraint in a web.xml file must be enforced, even on a static resource
  that is served by Apache instead of Tomcat.  Substantial modifications
  to MOD_JK would be needed to make this work (primarily in adding a
  two-way exchange of configuration information).

* MOD_JK had no committers interested in maintaining it, at the time
  that the decision was made.  Subsequent to that time, several
  volunteers have surfaced, including at least one person interested in
  supporting MOD_JK under Tomcat 4.0.  That would be fine with me,
  as long as the result obeys all the rules.
