I'm looking for an example of simple modular code in Java. After quite some researching, I'm only finding complex examples and "full" packages which also utilize larger frameworks and such. It seems like there would be a much simpler solution.
I'm assuming some usage of reflection and such. The modules don't need security considerations; they will only be provided and written by in-house developers. The reflection and interfacing is cake, but what I'm largely confused about is how to get the classes loaded dynamically at run-time when the JAR files may be dropped in place at any time.
