Add .JAR for using classes in Jython scripts

Scripts. I'm working my way to building a module for it so users can use the system.* namespace in there scripts.

My end goal is to expose the apache poi 4.1.0 to end users. I've been digging around the forums and I'm wondering if my end goal is not possible? Kevin mentions a weird corner case about possible conflicts with the reporting module because it uses poi-3.14.

I'm looking for a kick start in the right direction (Uninstalling the reporting module isn't an option for our client); is 4.1.0 not a good idea because of the reporting module? Is it a safer bet to use the same version as the reporting module? Is it possible to just access the existing POI library from all scopes?
