Apache Karaf is an enterprise grade application server for running OSGi applications. This presentation will give you an idea of how to build Enterprise Applications with Apache Karaf. Achim Nierbeck will cover a broad range of possibilities to use Apache Karaf in an enterprise environment. For example how to combine JPA, web-development and Clustering, all based on the Open-Source tools Apache Karaf, OPS4j Pax Web and Apache Karaf Cellar.

Developing modular web-based applications is easy using the HTTP-service implementation of Apache Felix. It hides the complexity and boilerplate code needed to get your servlets and filters up and running in no-time. With the recent effort in aligning the HTTP-service with the latest servlet specifications, new functionality like asynchronous servlets and filters will be supported out-of-the-box.
In this presentation we will not only talk about the new features provided by the Felix HTTP-service implementation, but also demonstrate how to use them in your project. In addition, we talk about upcoming improvements to the Felix HTTP-service, like native support for SPDY and WebSockets.

In this talk I will look into some good and bad examples of how to structure your business applications with a special focus on OSGi. I will show some anonymized examples encountered at customers of good and bad design and reflect on how the bad ones can be improved. Some highlights will be technical vs business focus in the structure, separating business code from technical code, Minimizing dependencies, designing for change
