I was able to get this to work.

I used pack200 to create a pack.gz and placed the jar and the pack.gz files in the lib/core/common.  
I restarted the gateway and my designer and I was able to run `from com.pubnub.api import Logger` without any errors.

Thanks to @Kevin.Herron in this post: [Adding java custom classes to Ignition](http://forum.inductiveautomation.com/t/adding-java-custom-classes-to-ignition/15202/2?u=code_skin)

NOTE\* his disclaimer about official support and the SDK is the way to go.
