unable to instantiate Amazon Pay java sdk in ColdFusion

Question

I'm working on implementing Amazon Pay, and instead of converting one of the SDKs to CF, figured I would just use the java sdk - but, I haven't ever worked with anything that is not part of the java core install. Any ideas why this

createObject('java', 'com.amazon.pay.api.WebstoreClient')

is not working ( Object instantiation exception. Error: org/json/JSONException.) when I drop the jar in cfusion\wwwroot\web_inf\lib.

the jar file came from here: https://github.com/amzn/amazon-pay-api-sdk-java/releases

I suspect that the issue is with the import statements for the "core" libraries, but don't know why CF wouldn't be able to find them (seems pretty basic) so I must be doing something wrong.

Windows 10 dev box running CF2016, dev install with a single instance, both restarted and rebooted.

ANSWERED BY @SOS IN THE COMMENTS - reposted here.

1. Downloaded the sdk to c:/path/to/lib/amazon-pay-api-2.5.1.jar.
2. Added

this.javaSettings = { 
    LoadPaths = [ "c:/path/to/lib/amazon-pay-api-2.5.1.jar"], 
    loadColdFusionClassPath=true };

3. Restarted Application.cfc

Edited to add code and complete error

This is the complete contents of the file that errors. I have tried both ways and get the same error - 
<!--- <cfobject action="create" type="java" class="com.amazon.pay.api.WebstoreClient" name="WebstoreClient"> --->

<cfset wsClient=createObject('java', 'com.amazon.pay.api.WebstoreClient')>

<cfdump var="#wsClient#">

The error

Object instantiation exception.
An exception occurred while instantiating a Java object. 
Error: org/json/JSONException.
 
The error occurred in E:/webroot/striking/d.cfm: line 2
1 : <!--- <cfobject action="create" type="java" class="com.amazon.pay.api.WebstoreClient" name="WebstoreClient"> --->
2 : <cfset wsClient=createObject('java', 'com.amazon.pay.api.WebstoreClient')>
3 : 
4 : <cfdump var="#wsClient#">
