Description:
In Tom Valesky's Enterprise JavaBeans, readers find a hands-on tutorial on writing real-world EJBs for the corporate enterprise. Valesky explores the history of distributed computing and the role of EJBs in the world of legacy CORBA and transaction processing. The author's presentation of the architecture of EJBs, both session and entity beans, is just excellent. The book also suggests how EJBs can be used together with RMI and CORBA. The examples in this book are its best feature. Using WebLogic's application server, the author first presents a simple "Hello world" example. There is also a simple online "shopping cart" example, written with both "stateless" and "stateful" session beans. You'll explore entity beans for connecting to corporate databases, and Valesky updates the shopping cart example to use them. EJBs are just part of the picture for enterprise development. As a bonus, this book provides a checklist of over 50 useful hints for writing successful distributed systems. The book includes a full-fledged example for an employee time-tracking system built with EJBs, along with full source code for all examples presented in the book. Enterprise JavaBeans is an excellent hands-on guide to real-world EJB development in a book that avoids the high-flown jargon that often appears in books on distributed programming. --Richard Dragan
