At the end of 2010 I reviewed the book “OSGi and Apache Felix 3.0 Beginner’s Guide“. The people from packt publishing contacted me based on my involvement in the past with OSGi and felix. I wrote a number of blog posts on OSGi and felix and gave a presentation at the NLJug together with Allard about the topic. During the process of reviewing, I got enthusiastic about the book. I think the result is a good book for people that want to learn about OSGi by getting their hands dirty.
