<A HREF="http://www.ibm.com/developerworks/edu/r-dw-r-revkick1.html?ca=drs-">Learn how to build a robust Web application</A> using Rational Application Developer, DB2, and WebSphere Application Server in this two-part series. In this tutorial, you'll learn how to install, set up, and configure trial versions of Rational Application Developer for WebSphere Software, DB2 Enterprise V9.0, and WebSphere Application Server V6.1. Perhaps you used open source versions of these products to kick-start your Web-based application development. This tutorial takes you the next step: scaling your application to run in a business environment. In Part 2, you will use Rational Application Developer to build a Web application using data from a DB2 database, and publish your page to a WebSphere Application Server, all without writing any code. IBM's middleware takes care of all the hard work so you can focus on your own unique business logic.
