Introducing EAServer

Sybase EAServer is an industrial-strength application server developed and marketed by Sybase, Inc. of Dublin, California. EAServer is an implementation of the Java 2 Platform, Enterprise Edition, more commonly known as J2EE. J2EE represents Sun's serious effort to make Java a powerful platform for developing enterprise applications. It defines a set of runtime architectures, network services, and application programming interfaces (APIs) that make it easy for developers to write distributed, network-aware software components and applications.

The current shipping version of EAServer at the time of this book's writing is 4.2. Version 4.2 has a lot in common with its immediate predecessors, especially versions 3.6.1 and 4.0, but there are also significant differences. Therefore, instead of trying to cover multiple versions of EAServer, this book focuses on version 4.2.
