This should be installed by default, but just in case it is not, you can add it manually.
You can find the httpd,conf file at /private/etc/apache2/httpd.conf
So in case when you install the ColdFusion server under JRun and the JRun settings do not get written in the httpd.conf file, just add this
# JRun Settings LoadModule jrun_module /Applications/JRun4/lib/wsconfig/1/mod_jrun22.so <IfModule mod_jrun22.c> JRunConfig Verbose false JRunConfig Apialloc false JRunConfig Ignoresuffixmap false JRunConfig Serverstore /Applications/JRun4/lib/wsconfig/1/jrunserver.store JRunConfig Bootstrap 127.0.0.1:51020 #JRunConfig Errorurl url <optionally redirect to this URL on errors> #JRunConfig ProxyRetryInterval 600 <number of seconds to wait before trying to reconnect to unreachable clustered server> #JRunConfig ConnectTimeout 15 <number of seconds to wait on a socket connect to a jrun server> #JRunConfig RecvTimeout 300 <number of seconds to wait on a socket receive to a jrun server> #JRunConfig SendTimeout 15 <number of seconds to wait on a socket send to a jrun server> AddHandler jrun-handler .jsp .jws .cfm .cfml .cfc .cfr .cfswf </IfModule>
Mine was written just above the last Module at the end of the file, so copy these JRun settings right above the last entry which is
Include /private/etc/apache2/other/*.conf <Files ~ ".hbmxml$"> Order allow,deny Deny from all </Files>
