Blog from November, 2013

In this talk from WJAX 2013 I show best practices for OSGi development in a practical example based around an online voting application.

The UI allows to vote on a topic and shows the existing votes in a diagram. It is done in Javascript and HTML using jQuery and google graph. Additionally votes can be sent using twitter, irc and karaf commands. The image below shows how to vote for the topic camel using your twitter status. 

The architecture of the example follows the typical separation of model, service layer and front end.

In the talk I explain the difficulties people typically face with OSGi and how to solve them using karaf, maven bundle plugin and blueprint.
