(Web) Applications Made Simple with OSGi - Peter Kriens

OSGi Community Event 2013 (

OSGi is renowned for its advanced modularity but it is not often called simple. I actually believe that OSGi is simple but that most reported problems are caused by trying to push a square through a round hole. Problems are invariably caused by trying to apply incumbent non-modular technology through a modular framework. However, today the average developer has not much choice, most of the free and available components use hacks that are not compatible with strong modularity, nor do they leverage OSGi's features like µservices and central dynamic config admin as they were intended.

Spending a sabbatical year developing a web application the 'OSGi Way' it was clear that a lot of components and documentations is missing to quickly build a web application the 'OSGi Way'. To leverage OSGi to the hilt I had to develop too many base components. Though I proved to myself that OSGi was really working as advocated if you go with the flow, it was clear that other developers have neither the time, OSGi experience, nor the inclination to do what I could do. Discussing these experiences with the OSGi Alliance we therefore decided to turn this into a project!

This presentation will show you my experiences with developing a truly OSGi Web App and an overview of the OSGi Alliance's plans to simplify development of OSGi (web) applications.

Peter Kriens is an independent consultant since 1990.He currently works for the OSGi Alliance and jpm4j. During the eighties he developed advanced distributed systems for newspapers based on microcomputers based on, at the time very novel, object oriented technologies. For this experience in Objects he was hired by a number of international companies, including Adobe, Intel, Ericsson, IBM, and many others. During his work at Ericsson Research in 1998 he got involved with the OSGi specification; Later he became the primary editor for these specifications. In 2005 he was awarded the OSGi Fellows title. After taking a sabbatical in 2012 to develop jpm4j he returned to the OSGi Alliance to help increasing adoption. He is Dutch but decided to live in France.
