Before you start
The Hello World series is for novice developers who want a high-level, hands-on overview of IBM software products. Each tutorial in the series provides simple exercises and step-by-step instructions to familiarize you with the components and use of a particular product. Upon completing a tutorial in the Hello World series you will know enough about the product to begin exploring and using it on your own.
This first tutorial in the Hello World series has been updated for Rational Software Architect V7. The tutorial guides you step-by-step through the process of designing and developing a simple service-oriented application using Rational Software Architect V7. It includes practical exercises that show you how to use UML diagrams to design the application, publish the model information to a Web page, and transform the design to Java code. This tutorial concludes with an introduction to Rational Software Architect's true round-trip engineering (RTE), which supports the process of forward- and reverse-engineering Java code. The original version of this tutorial for Rational Software Architect V6 is still available. For introductions to other products that play key roles in a service-oriented architecture, see the complete list of Hello World tutorials.
This tutorial is for beginning application developers and requires no experience with Rational Software Architect. Rational Software Architect V7 is built on Eclipse 3.2 and includes support for JDK 5. To get the most out of the tutorial you should have some experience using the Eclipse development environment.
