Technology Overview The Java 2 Enterprise Edition (J2EE) specification is one of Java's success stories; a standard for enterprise web application development that has wide industry support.
J2EE is basically a collection of specifications for web services, business objects, data access, and messaging. They define the way in which web applications communicate with the servers that host them. J2EE focuses on two things - creating a standard that allows web applications to be portable between servers, and giving the server control of component lifecycle and other resources, in order that it can handle issues of scaling, concurrency, transaction management, and security.
This book is based around one of the most popular J2EE and EJB implementations, BEA WebLogic Server. The authors work for BEA in Europe, providing technical support for customer's implementations of Weblogic-based solutions. They have first-hand knowledge of the practical difficulties developers face in applying J2EE and WebLogic to their projects, and in debugging and testing these applications. This book is a distillation of their real-world expertise.
Who is this book for?
This book is for professional Java developers who want to see the development of a full J2EE example and its configuration and deployment on BEA WebLogic Server. Coverage of the APIs involved, reasoning behind the architecture decisions made, and how the example is tested, is included.
Java knowledge is assumed, as is a basic tutorial understanding of the J2EE APIs. Some experience of enterprise level / web application programming is expected.
What does this book cover?
Moving a client/server app to the web using J2EE APIs Interfacing multiple front ends to the underlying business logic How to create business logic components with Enterprise JavaBeans Using Java Message Service for reliable and broadcast messaging WebLogic Server-specific programming and configuration detail Security concerns for an e-commerce site The Grinder, a stress-tester for web applications Results of stress-tests compare application architectures under different loads Full working example developed and tested in the book
Peter Zadrozny and Francisco Gomez work for BEA in Europe, providing technical support for customer's implementations of Weblogic-based solutions. They thus have first-hand knowledge of the problems developers face in applying WebLogic, EJBs and in tuning, debugging and testing these applications.
