I got these instructions from Mark Drew's Site except I had some problems or didn't understand how to do something correctly. So here is my version of these instructions. Basically I am posting these instruction for myself How I installed it was as follows:

1. Run the installer, and select Multiserver
2. Do all the settings as you want, I installed it into Applications/JRun4
3. Once it has installed, it wont be able to go the web based configuration tool as it seems the server hasn’t actually started, so, open up Terminal (Utilities/Terminal)
4. Type sudo /Applications/JRun4/bin/jrun -start admin
5. Then type sudo /Applications/JRun4/bin/jrun -start cfusion
6. Coldfusion should start, but it isn’t properly configured so go to: http://localhost/cfide/administrator/index.cfm (note the index.cfm, apache isn’t configured to serve index.cfm as a default file yet)
7. Once you have gone through the process, open up /etc/apache2/httpd.config and look for the line : DirectoryIndex index.html and change it to DirectoryIndex index.cfm index.html
8. Restart apache by opening another Terminal window and type: sudo apachectl restart

Apache Config info:




Then bring Terminal up and type in sudo java -jar /Applications/JRun4/lib/wsconfig.jar which will bring up these next series of screen shots came from.









Now download this file mod_jrun22_64.zip which i got from Scott Pinkston's site and unzip to /Applications/JRun4/lib/wsconfig/1 restart the webserver and you should be up and running. One other thing your web root should be /Library/WebServer/Documents/ if you did the default install.

Edit: If you turn on your firewall make sure you add Jrun and Java to the incoming traffic.
