This tutorial describes how to create a very simple Hello World style of JBI service engine (SE) component. It demonstrates some best practices for creating JBI components. The example in this tutorial is as minimalistic as possible so as to focus on key concepts and not drown in details. The example component will respond to all requests with the message:

<hello>Hello World! Message \[<original message here>\] contains \[??\] bytes.</hello> |
Hello, I received <xyz> bytes! |
Prerequisites
- Maven 2.0.4 or higher
- If you have never used Maven previously the Maven Getting Started Guide explains some valuable concepts surrounding Maven
- ServiceMix 3.1 or higher
- A broadband internet connection (so Maven can automatically download dependencies)
