Enterprise Javabeans by Example with Cdrom

From the Book: PREFACE: Preface Dear Reader, You have begun a book that is unique in many ways. First, the team who wrote this book are IBM and external technical professionals from countries around the globe. They were part of a short project exploring the new component architecture of Enterprise JavaBeans. Second, this publication is meant to smoothly connect theoretical and practical elements into one natural flow; in doing this, the book will easily find its home on the bookshelves of architects and consultants, and, likewise, it could find its place on the desk of developers to guide them through their first steps in the implementation of this new architecture. This book goes beyond the technical value of Java and JavaBeans and looks at adding real business value to an enterprise. IBM, Sun, and several other vendors have worked together to create the Enterprise JavaBeans (EJB) specification. With this specification, developers can create server-side business components in Java, suitable for use in industrial-strength object-oriented and multitiered applications. This means Java components receive full life-cycle support and can participate in transactions and interoperate with resource managers, such as database managers, in a secure fashion. Extending the principles of its Java heritage, The EJB specification also incorporates the notion of develop once, deploy anywhere. With EJBs, it becomes possible to create reusable server-side Java components that can be managed in the runtime environment of any vendor who provides EJB servers conforming to the specification. The team who wrote this publication tried toanswerwhy, what, and how questions in that order. So, after you have practical experience with the simple sample scenarios, you should have a solid understanding of Enterprise JavaBeans and be ready to study this fascinating technology more deeply. We wish you good luck in this endeavor.
