I have written a Java program designed to run server-side with a plain HTML web interface:
- I am reusing and I have integrated in this app a bunch of third-party libraries that are licensed under the GPLv3. Some are pure Java, some are a combo of C/C++ and Java. I am calling their methods from my Java code.
- These libraries do not contribute directly to the UI of my app, but rather perform utility functions on the back-end, though some output can be made available to users for download in my web app.
- I use all these libraries as-is and unmodified: I use only the pre-compiled binary Jars as provided by the projects.
In each of the following cases, when would I have to redistribute the source code of my own application and of this library per the GPLv3?
e.g. when is the copyleft triggered for my unmodified usage?
When I run this web application on a private company network and its is only available internally to my company employees?
When I run this application as a public web site on the open internet?
When I redistribute this application (including the GPLv3 libraries) as a packaged software product to a third party?
For clarity: none of these libraries have a GPL exception: they are using the full GPLv3
