Camel in Action is a Camel tutorial full of small examples showing how to work with the integration patterns. It starts with core concepts like sending, receiving, routing, and transforming data. It then shows you the entire lifecycle and goes in depth on how to test, deal with errors, scale, deploy, and even monitor your app—details you can find only in the Camel code itself. Written by the developers of Camel, this book distills their experience and practical insights so that you can tackle integration tasks like a pro.

About the Technology
Apache Camel is a Java framework that lets you implement the standard enterprise integration patterns in a few lines of code. With a concise but sophisticated DSL you snap integration logic into your app, Lego-style, using Java, XML, or Scala. Camel supports over 80 common transports such as HTTP, REST, JMS, and Web Services.
What's inside
- Valuable examples in Java and XML
- Explanations of complex patterns
- Error handling, testing, deploying, managing, and running Camel
- Accessible to beginners, useful to experts
