In Detail

The goal of Java Business Integration (JBI) is to allow components and services to be integrated in a vendor-independent way, allowing users and vendors to plug and play.

Java Business Integration (JBI) is a specification aiming to define a Service Provider Interface for integration containers so that integration components written for these containers are portable across containers and also integrate with other components or services using standard protocols and formats. JBI is based on JSR 208, which is an extension of Java 2 Enterprise Edition (J2EE).

This book first discusses the various integration approaches available and introduces the Enterprise Service Bus (ESB), a new architectural pattern that facilitates integrating services. ESB provides mediation services including routing and transformation. Java Business Integration (JBI) provides a collaboration framework that provides standard interfaces for integration components and protocols to plug into, thus allowing the assembly of Service-Oriented Integration (SOI) frameworks following the ESB pattern. Once JBI and ESB are introduced, we look at how we have been doing service integration without either of these using traditional J2EE. The book then slowly introduces ESB and, with the help of code, showcases how easily things can be done using JBI.

Get hands-on guidance to ESB based Integration using lightweight, open-source Java Business Integration tools.

Approach

The book covers all concepts with examples that can be built, deployed, and run by readers using the Apache Ant tool in Apache ServiceMix, which is an open-source Enterprise Service Bus that combines the functionality of a Service Oriented Architecture (SOA) and an Event Driven Architecture (EDA).

The aim of this book is to prepare an architect or developer for building integration solutions using ESB. To that end, this book takes a practical approach, emphasizing how to get things done in ServiceMix with code. When needed, it delves into the theoretical aspects of ESB, and such discussions are supplemented with working samples. The book, thus, distils some of the knowledge that has emerged over the last decade in the realm of Java Integration.

Who this book is for

This book is aimed at Java developers and integration architects who want to become proficient with the Java Business Integration (JBI) standard. Readers should have some experience with Java and have developed and deployed applications in the past, but need no previous knowledge of JBI. The book can also be useful to anyone who is struggling to understand ESB and how it differs from other architectures and to understand its position in SOA.

This book primarily targets IT professionals in the field of SOA and Integration solutions, in other words, intermediate to advanced users. You are likely to find the book useful if you fall into any of the following categories:

• A programmer, designer, or architect in Java who wants to learn and code in JBI or ESB.

• A programmer, designer, or architect who doesn't normally code in Java can still benefit from this book, since we 'assemble integration components' using XML with little to no Java code.

• An IT Manager or an Officer who knows well about SOA or SOI but want to see something in code (you can adorn your flashy presentations with some live code too).
