Last week, Neil Bartlett and myself presented a session at JSig on the subject of OSGi and Dynamic Java Applications. It's gotten a couple of good reviews already, as well as some eager anticipation.
The demo was almost completely successful, which given the nature of these things is a good result, and the audience asked a few interesting questions. As usual, the time was against us and I had to make my excuses and return with haste at the end -- but Neil was around to field the questions that came up afterwards.
So, if you've ever wondered how to build a dynamic Swing OSGi application with NetBeans, you might like to take a look at the presentation, screencasts and downloadable code. Any questions should be posted to the EclipseZone thread.
