This IBM Redbook provides you with sufficient information to effectively use the WebSphere and VisualAge for Java environments to create, manage and deploy Web-based applications using methodologies centered around servlet, JavaServer Pages, and JavaBean architectures. In Part 1 we describe the products used in our environment and provide instruction on product installation and configuration. Following this, we cover servlet and JSP programming, which provide you with both a theoretical and practical understanding of these components, together with working examples of the concepts described. For execution of the sample code, we provide information on configuring the WebSphere Application Server and deploying and running the sample Web applications in WebSphere. Using the knowledge developed in these chapters, we then provide detailed information on the development environments offered by VisualAge for Java and WebSphere Studio. These chapters assist you in using the features offered by these tools, such as integrated debugging, the WebSphere Test Environment, Studio Wizards, and publishing of Web site resources. We also describe how Rational's ClearCase product can be integrated with our environment for Software Configuration Management. In Part 2 we describe the Pattern Development Kit sample application, including installation, configuration, and operation. We also discuss the application's use of Patterns for e-business, which presents information on some of the design decisions employed when creating the application. This IBM Redbook is intended to be read by anyone who requires both introductory and detailed information on software development in the WebSphere environment using servlets and JavaServer Pages. We assume that you have a good understanding of Java and some knowledge of HTML.
