Service Oriented Architecture (SOA) represents a fundamental shift in
the way applications are built, deployed, and used (or reused). By
moving from big, monolithic applications to smaller, re-usable Web
services, companies can dramatically reduce time-to-market, increase
maintainability and flexibility over the applications they build.

This session starts with a brief discussion on the benefits of a SOA
architecture. The majority of the session is devoted to explaining and
demonstrating several concrete technologies that make SOA architecture
possible - BPEL (Business Process Execution Language), JBI (Java
Business Integration), and OpenESB. The part of of BPEL starts with an
explanation of the requirements of standardized business process
language. The BPEL language is then described using an example. The
relationship between BPEL and WSDL is also explained. Finally, BPEL
designer and runtime that comes with NetBeans IDE 6.0 is demonstrated
using Travel reservation sample BPEL project. It also explains the
motivation of the JBI and OpenESB as a standardized integration
framework in the same way J2EE architecture standardized how enterprise
applications are built and deployed over standardized architecture.
Finally Sun's solution in SOA and application integration space is
discussed. Whenever possible, concrete steps of building, deploying, and
testing SOA applications will be demonstrated step by step.
