This IBM Redbook provides you with information that will allow you to use VisualAge Pacbase 3.0 (VAP) to create, manage, and deploy e-business applications in an application repository environment. In Part 1, we focus on the installation of VisualAge Pacbase and the administration and use of the product. We describe the targeted application architecture and provide an overview of the products, other required tools, and their integration with VisualAge Pacbase, as well as the VisualAge Pacbase development model. We present the advantages of using the VisualAge Pacbase proxy for e-business applications and explain how to build a view with the proxy on the client side of the application. In Part 2, we develop an e-business application using VisualAge Pacbase 3.0, WebSphere Studio, and VisualAge for Java. We discuss design, construction, testing, and implementation. Our sample application establishes a Web site for the VisualAge Cruise Line sample and provides a WAP version of the implementation as well.
