Hi Paul, i just messed it up, i uploaded the new cfcs from the link you gave me
in the previous post, but now i get this error again?

any ideas what i need to do

java init failed: net.sf.javainetlocator.InetAddressLocator
Class not found: net.sf.javainetlocator.InetAddressLocator

The error occurred in
D:\inetpub\vhosts\thesmsengine.com\httpdocs\geoLocator.cfc: line 92

you only need to upload the jar, the old CFC based on javaLoader is fine. put
the new jar in another location & just point the javaloader bits at the new
location.

i don't have the version i made for you in front of me but look in the init
method, there should be an argument something like "geoLocatorJarFile" or
failing that look for "InetAddressLocator.jar" in the init.

Hi Paul, i am getting confused, just want to check that i have the right cfcs
below and which line i need to change,

i have added both the ***JavaLoader.cfc*** and the ***GeoLocator.cfc*** below

thanks ryan
