OSGi enRoute is an OSGi application framework that makes OSGi (and Java) as easy to use as more dynamic web languages, while still providing the benefits of strong modularity. In this tutorial we start from an empty web page up to a simple but complete blog application that uses JPA on a combination of Hibernate, EclipseLink, H2 and MySQL.

 

The tutorial will use bnd(tools) and has a number of stages:

  1. We first start with handling web resources using the OSGi enRoute support. This will show bootstrap and a bit of Javascript code using Angular JS.
  2. The Javascript code is connected to the server using restful services. 
  3. We create a blog service to separate usage and implementation, creating a simple memory based blog database.
  4. The blog service is tested with OSGi Unit tests 
  5. An alternative implementation is created using JPA 
  6. The application is packaged and deployed in the cloud

 

This tutorial will teach you what makes OSGi so unique, and so easy to use if you use it in the intended way. Along the way you may learn a number of good techniques to use in rich internet applications.
