HMAC MD5 Hash Error

i am tryingti implement the linshare affiliate program in Cf
using this method

Linkshare affiliate program in Coldfusion

in this method it talks about the failure of the HMAC MD% function in Coldfusion and uses this java component method to get around it.

i have 90% of this implemented but i cannot get the component recognized by the server and so am stuck on the final stage.

here is the error i am getting.


"Could not find the ColdFusion Component or Interface /components.utils. Ensure that the name is correct and that the component or interface exists.
The error occurred on line 87.
on the /ls_post.cfm page "


The relevant code is attached

i have a components folder sitting in the webroot and a utils.cfc in there containing all the stuff to perform the HASH.

can anyone see why the server is not recognizing the component?

thanks
