Preface

This Developer's Guide describes how to create and run Java^TM 2 Platform, Enterprise Edition (J2EE^TM platform) applications that follow the open Java standards model for J2EE components and APIs in the Sun Java System Application Server environment. Topics include developer tools, security, assembly, deployment, debugging, and creating lifecycle modules.

Who Should Use This Book

This Developer's Guide is intended for use by software developers who create, assemble, and deploy J2EE applications using Sun Java System servers and software. Application Server software developers should already understand the following technologies:

Java technology
The Java 2 Platform, Enterprise Edition (J2EE platform), version 1.4
Hypertext Transfer Protocol (HTTP)
Hypertext Markup Language (HTML)
Extensible Markup Language (XML)

How This Book Is Organized

The Developer's Guide has three parts and an Appendix:

Part I, Developing and Deploying Applications includes general development topics relevant to the Application Server, such as security and debugging.
Part II, Developing Applications and Application Components describes J2EE application components, such as servlets and message-driven beans, that can run on the Application Server.
Part III, Using Services and APIs describes services and APIs that provide Application Server resources, such as JDBC and JNDI.
Appendix A, Deployment Descriptor Files describes deployment descriptor files specific to the Application Server.

The following table summarizes the chapters in this book.
