The installation scripts for libapache-mod-jk will insert the necessary lines into here, but I don't like the way they do it, so here's what I do:
I add ``LoadModule jk_module /usr/lib/apache/1.3/mod_jk.so'' somewhere before ``LoadModule rewrite_module /usr/lib/apache/1.3/mod_rewrite.so''
The scripts will place a section that looks like this in the file:
# The following line is for apacheconfig - DO NOT REMOVE!
</IfModule>If it's located near the end of the file, it's fine. Otherwise that might be a good location for it. Note the ``Include'' line, that file is an automatically generated file that is outputted by Tomcat.
