A really bare-bones platform
My friend Jarda has a NetBeans-based application which uses only the NetBeans module system - i.e. you can use the NB module system to write server-side modular applications or whatever you want. It's a SourceForge project called DVB Central, which I believe he wrote for controlling his home video setup (signal comes into the computer and is routed to one of various destinations).
It's a pretty cool example of just what you can do with the NetBeans platform. The crack-cocaine of coding for NetBeans is the module system - the fact that you can have public classes that are public only within their own JAR, so you can design really clean, well-separated APIs. And it comes with a Manifesto - what's not to love about that?
We'll probably use DVBCentral as part of our workshop at OOPSLA 2006 in Portland, Oregon this October.
