Hence, let us not delve into
the intricacies of WSDL and SOAP, as there are many text books doing the same. Let
us continue with our discussion on integration.
Java Business Integration

Service Oriented Integration (SOI)
In Chapter 1, we identified ESB as an architectural pattern different from traditional
integration architectures, which support standards-based services for integration.
Gartner originally identified ESB as the core component in an SOA landscape.
Gartner says:
SOA will be used in more than 80% of new mission-critical applications and
business processes by 2010
Another market strategy study, conducted by Gartner in SOA reveals that:
The ESB category grew by 160% from year 2004 to year 2005
As is true with SOA, ESB-based integration has been increasingly using web services
standards and technologies for service description, hosting, and accessing. The
advantage is that we not only reap all the benefits of ESB architecture (explained in
Chapter 1), but also make sure that the services exposed at the bus are complying
with industry standards. This means consumers and providers makes use of
existing toolsets and frameworks to interact with the ESB.
