"This IBM Redbook provides detailed information on how to effectively use VisualAge for Java Enterprise for the development of applications based on the Enterprise JavaBeans architecture, and deployment of such applications to a WebSphere Application Server. This redbook is a companion book to the redbooks on IBM Patterns for e-business. In Part 1 we introduce Enterprise JavaBeans as a part of Java 2 Enterprise Edition and cover the basic concepts and the architecture. We also introduce the IBM products that support this architecture. In Part 2 we describe the IBM development and test environment for enterprise beans, and we create rather simple container-managed and bean-managed entity beans, session beans, finder methods, access beans, and client programs. We explain the basic transaction management facilities and describe how to deploy enterprise beans to a WebSphere Application Server. In Part 3 we explore advanced facilities for mapping entity beans to database tables, including the extended IBM support for inheritance and associations. We describe how these advanced facilities are used in client programs and touch on exception handling, security, and modeling with Rational Rose. In Part 4 we provide design guidelines and best practices when developing applications based on enterprise beans. Throughout the book we provide examples based on a simple banking application with an underlying relational database."
