The Java 2 Platform, Enterprise Edition (J2EE)

Overview of the Book and Technology:

The Java 2 Platform, Enterprise Edition (J2EE) defines the standard for developing n-tier enterprise applications using Java. J2EE simplifies enterprise applications by basing them on standardized modular components and providing for those components a complete set of services that handle the complexities automatically.

N-tier applications are difficult to build. Usually building such an application requires people with a variety of skills and an understanding of both modern and legacy code and data. Enterprise applications typically use heterogeneous approaches to systems development and require the integration of tools from a variety of vendors and the merging of disparate application models and standards.



This book covers the various components of J2EE that are used to build enterprise n-tier applications, including the following:

• JavaServer Pages (JSP)
• Enterprise JavaBeans (EJB)
• Java Messaging Service (JMS)
• Java Naming and Directory Interface (JNDI)
• Java Authentication and Authorization Service (JAAS)
• Java Connector Architecture (JCA)
• And more . . .

The author team recommends that the chapters in this book be read in order, as each chapter builds upon previous chapters. If reading the chapters in order is not viable, reading a particular section in a single sitting may be a better choice.
