Java With a Bit of OSGi – The Book

I’m dancing. By god I’m dancing on the walls. I’m dancing on the ceiling. I’m ecstatic. I’m overjoyed. I’m really, really pleased. – An excerpt from the Foreword by Uncle Bob (aka. Robert C. Martin) My book, Java Application Architecture: Modularity Patterns With Examples Using OSGi is now available. Uncle Bob and Peter Kriens each contributed Forewords […]
