Took me a little bit to find the solution for this across several different board posts so I thought I’d quickly write it up.
For those of us still using FarCry 3 (remember that FarCry 5 is out!) you may come across the following error:
“java init failed: net.sf.javainetlocator.InetAddressLocator”
The docs tell us:
Geolocator is a plugin that determines the locale of an inbound request. Its an optional plugin that is turned off by default, and requires a class file InetAddressLocator to be placed in your class path.
You may be getting this error because you have migrated or copied an application to a server environment that is not correctly configured for the plugin.
You can either turn it off by getting into the ADMIN>>CONFIG>>PLUGINS – or drop the InetAddressLocator class into your JAVA class path.
Remember however that if you have this problem, you can’t login to FarCry to make the config change 
In which case you can open your database and make the change manually. Open up the “config” table and edit the “plugins” row (row 9) in which there is a small wddx packet. You want to change the value of the “GEOLOCATOR” value, it should be “no” as follows:
<var name=’GEOLOCATOR’><string>No</string></var>
After this run an update app (/index.cfm?updateapp=1) and you should be fine. If your site is up and running now then read no further, otherwise:
But wait…there’s more!
Let’s say that your GEOLOCATOR setting is now (or already was) set to “no” but you are still getting the error. Could it be that the “farcry_core” directory is not sitting at the same level as your project directory?
If this is the case then this could help you:
Open up /config/_serverSpecificVars.cfm in your project and change the value of application.path.core to be an absolute path to the farcry_core directory on your server (or use expandPath()).
Something like:
application.path.core = expandPath('/farcry/farcry_core/');
or:
application.path.core = '/vhosts/farcry/farcry_core';
Run an updateapp and now you should be fine
