Binildas A. Christudas [Binildas A. Christudas] - Service Oriented Java Business Integration: Enterprise Service Bus integration solutions for Java developers

In DetailThe goal of Java Business Integration (JBI) is to allowcomponents and services to be integrated in a vendor-independentway, allowing users and vendors to plug and play.Java Business Integration (JBI) is a specification aiming todefine a Service Provider Interface for integration containers sothat integration components written for these containers areportable across containers and also integrate with other componentsor services using standard protocols and formats. JBI is based onJSR 208, which is an extension of Java 2 Enterprise Edition(J2EE).This book first discusses the various integration approachesavailable and introduces the Enterprise Service Bus (ESB), a newarchitectural pattern that facilitates integrating services. ESBprovides mediation services including routing and transformation.Java Business Integration (JBI) provides a collaboration frameworkthat provides standard interfaces for integration components andprotocols to plug into, thus allowing the assembly ofService-Oriented Integration (SOI) frameworks following the ESBpattern. Once JBI and ESB are introduced, we look at how we havebeen doing service integration without either of these usingtraditional J2EE. The book then slowly introduces ESB and, with thehelp of code, showcases how easily things can be done usingJBI.What you will learn from this book?

• Assembling services and porting them across containers usingJBI

• 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 externallyaccessible WSDL-compliant services

• Providing a web service gateway for external consumers

• Accessing web services over a reliable transport channel likeJMS

• Implementing web service versioning using ESB

• Implementing service aggregation at ESB

• Transactions, Security, Clustering, and JMX in ESB

ApproachThe book covers all concepts with examples that can be built,deployed, and run by readers using the Apache Ant tool in ApacheServiceMix, which is an open-source Enterprise Service Bus thatcombines 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 forbuilding integration solutions using ESB. To that end, this booktakes a practical approach, emphasizing how to get things done inServiceMix with code. When needed, it delves into the theoreticalaspects of ESB, and such discussions are supplemented with workingsamples. The book, thus, distils some of the knowledge that hasemerged 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 architectswho want to become proficient with the Java Business Integration(JBI) standard. Readers should have some experience with Java andhave developed and deployed applications in the past, but need noprevious knowledge of JBI. The book can also be useful to anyonewho is struggling to understand ESB and how it differs from otherarchitectures and to understand its position in SOA.This book primarily targets IT professionals in the field of SOAand Integration solutions--in other words, intermediate to advancedusers. You are likely to find the book useful if you fall into anyof the following categories:

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

• A programmer, designer, or architect who doesnt normally codein Java can still benefit from this book, since we assembleintegration components using XML with little to no Java code.

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