Any such activity will complicate the already confused stove
pipes and it is the need of the hour to have standardization. Here we are going to
inspect the need of another standard for business integration, and also look into the
details of what this standard is all about.
So we will cover the following in this chapter:
Service oriented architecture in the context of integration
Relationship between web services and SOA
Service oriented integration
J2EE, JCA, and JBI??”how they relate
Introduction to JBI
JBI Nomenclature??”main components in JBI
Provider-consumer roles in JBI
JBI Message Exchange Patterns (MEP)
SOA??”The Motto
In Chapter 1, we went through integration and also visited the major integration
architectures. We have been doing integration for many decades in proprietary or
ad-hoc manner. Today, the buzz word is SOA and in the integration space, we are
talking about Service Oriented Integration (SOI). Let us look into the essentials
of SOA and see whether the existing standards and APIs are sufficient in the
integration space.

Why We Need SOA
We have been using multiple technologies for developing application components,
and a few of them are listed as follows:
Remote Procedure Call (RPC)
Common Object Request Broker Architecture (CORBA)
Distributed Component Object Model (DCOM)
