This chapter will address some of the reasons for using a Web Services architecture, as well as explore some of the options to consider when integrating systems with the outside world.
In this chapter, I’ll walk you through a real-life project that involves exposing a set of services to a business partner, and discuss some design choices that were made along the way. Technologies that were used included Java (J2EE), XML, the Rosettanet E-Business protocol, and a function library used to communicate with a program running on an AS/400 system. I will also cover the use of interfaces and the factory design pattern as I show how I made the system extensible for future distributors who may use different protocols and may need to access different services.
