✦ Synopsis

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.
What you will learn from this book?

• Assembling services and porting them across containers using
  JBI

• Exposing EJB as a WSDL-compliant service across firewalls

• Binding remote services to ESB to be consumed internally

• Exposing local components in ESB like POJO as externally
  accessible WSDL-compliant services

• Providing a web service gateway for external consumers

• Accessing web services over a reliable transport channel like
  JMS

• Implementing web service versioning using ESB

• Implementing service aggregation at ESB

• Transactions, Security, Clustering, and JMX in ESB

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 written 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).
