Part 1. Core Mule

Mule is a lightweight, event-driven enterprise service bus and an integration platform and broker. As such, it resembles more a rich and diverse toolbox than a shrink-wrapped application. In the first chapter of this book, we’ll introduce you to the history of its origins and the competing projects that exist on the market, and then we’ll immediately dive into a quick tutorial that will get your feet wet and your mouth watering!

In chapter 2, we’ll go through an extensive review of the principles involved in processing messages with Mule. You’ll learn the notions of flows, message sources, and processors and will look deep into the structure of the Mule message. The Mule Expression Language (MEL) will be introduced too.
