There are many ways to handle data exchange between applications and systems.

Instant Apache Camel Messaging System introduces you to Apache Camel and provides easy-to-follow instructions on how to set up a Maven-based project and how to use unit tests and mocks to develop your application in a "test first, code later" manner. This book will help you take advantage of modern Java development infrastructures including the Spring Framework, Java DSL, Spring DSL, and Apache Camel to enhance your application.
