Computer: Mac 10.6.4

CF: 9.1 - multi server instance

MAMP with Apache 2.2

I've recently inherited a computer from a co-worker who already had CF installed and running.  Instead of wiping the computer and starting from scratch I just signed on under my account and so far everything has been running smoothly.  MAMP, JRun Console, starting and stoping JRun instances, and viewing the admin panel on localhost:8000

However it seems that apache is not able to render/recognize coldfusion.  I've gone through all of the CF steps in setting it up with apache, compared it with a working instance on my older computer and confirmed that everything is the same.  JRun is installed in /Application directory so I'm under the impression that everything needed is installed for all users and not just under his account.

Using CF Server Instances already installed and configured by him, my vhost looks like this:

<VirtualHost *>

    DocumentRoot "/Users/{me}/Documents/project/sample"

    ServerName sample

    ServerAlias sample.localhost

    <Directory "/Users/{me}/Documents/project/sample">

        Options Indexes FollowSymLinks

        AllowOverride All

        Order allow,deny

        Allow from all

    </Directory>

    JRunConfig Serverstore "/Applications/JRun4/lib/wsconfig/1/jrunserver.store"

    JRunConfig Bootstrap 127.0.0.1:51000

    JRunConfig Apialloc false

    ErrorLog "/Applications/MAMP/logs/sample_error_log"

</VirtualHost>

Apache is running on port 80 and I've confirmed that 51000 is correct.  sample_error_Log and the apache error log do not report anything wrong.  This is the message I get from apache as I hit http://sample/

500

java.lang.NullPointerException

stDispatcher.java:285)

     at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:428)
     at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66)

Anyone have suggestions? Or know if I need to install CF 9 on my user account?  Thanks!
