When Camel Smiles
The document discusses Apache Camel, an open-source integration framework designed for enterprise integration patterns. It details the architecture, components, and usage of Camel, emphasizing its distinction from traditional ESB and message broker solutions. Additionally, it highlights key contributors and suggests resources for learning more about Camel.

Editor's Notes
- #5 http://www.eaipatterns.com/Introduction.html Distributed Applications vs. Integration This book is about enterprise integration—how to integrate independent applications so that they can work together. An enterprise application often incorporates an n-tier architecture (a more sophisticated version of a client/server architecture) enabling it to be distributed across several computers. Even though this results in processes on different machines communicating with each other, this is application distribution, not application integration. Why is an n-tier architecture considered application distribution and not application integration? First, the communicating parts are tightly coupled—they dependent directly on each other, so that one tier cannot function without the others. Second, communication between tiers tends to be synchronous. Third, an application (n-tier or atomic) tends to have human users that will only accept rapid system response. In contrast, integrated applications are independent applications that can each run by itself, but coordinate with each other in a loosely coupled way. This enables each application to focus on one comprehensive set of functionality and yet delegate to other applications for related functionality. Integrated applications communicating asynchronously don’t have to wait for a response; they can proceed without a response or perform other tasks concurrently until the response is available. Integrated applications tend to have a broad time constraint, such that they can work on other tasks until a result becomes available, and therefore are more patient than most human users waiting real-time for a result.

But please do always use these helper classes, pure File or JMS integration with try-catch-error is soooo ugly!
