The book concentrates on leveraging Java Business Integration (JBI) for addressing real world
integration problems with examples. Business level integration in Java needs to address
integrating multiple flavors of business components including POJO, EJB, Web Services, JMS,
etc. The book will explain all the above scenarios, using open source Apache ServiceMix as the
ESB framework.
In Detail:
The book first discusses the various integration approaches available and introduces Enterprise
Service Bus (ESB), which is a new Architectural pattern which can facilitate integrating services.
ESB provides different forms of mediation services including routing and transformation. Java
Business Integration (JBI) provides a collaboration framework which 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. JBI is based on JSR 208, which
is an extension of Java 2 Enterprise Edition (J2EE). Once JBI and ESB are introduced, we look at
how we have been doing service integration without either of the above using traditional J2EE.
The book then slowly introduces ESB and showcases with the help of code, how easily things can
be done using JBI.
* Assemble services and port it across containers using JBI
* Expose EJB as WSDL compliant service across firewalls
* Bind remote services onto the ESB to be consumed internally
* Expose local components in ESB like POJO as WSDL compliant services
to be accessible externally.
* Provide a web service gateway for external consumers
* Access web services over reliable transport channel like JMS
* Implement web service versioning using ESB
* Implement service aggregation at ESB
* Transactions, Security, Clustering & JMS in ESB.
Who this book is written for?
This book is aimed at Java developers and integration architects aiming to become proficient with
Java Business Integration (JBI) standard, who are expected to have some experience with Java and
to have developed and deployed applications in the past, but need no previous knowledge of JBI.
The book can also be useful to anyone, who has been having a hard time understanding ESB and how
it differs from other architectures and to understand its position in SOA.
