What Is the JavaTM 2 Platform, Enterprise Edition?
This document provides an introduction to the features and benefits of the
Java 2 platform, Enterprise Edition.
Overview
Enterprises today need to extend their reach, reduce their costs, and lower
their response times by providing easy-to-access services to their
customers, partners, employees, and suppliers.
Typically, applications that provide these services must combine existing
enterprise information systems (EIS) with new business functions that
deliver services to a broad range of users. These services need to be:
Highly available, to meet the needs of today's global business environment.
Secure, to protect the privacy of users and the integrity of enterprise
data.
Reliable and scalable, to insure that business transactions are accurately
and promptly processed.
For a variety of reasons, these services are generally architected as
distributed applications consisting of several tiers, including clients on
the front end, data resources on the back end, and one or more middle tiers
between them where the majority of the application development work is done.
The middle tier implements the new services that integrate existing EISs
with the business functions and data of the new service. The middle tier
shields the client tier from the complexity of the enterprise and takes
advantage of rapidly maturing Internet technologies to minimize user
administration and training.
The Java 2 platform, Enterprise Edition reduces the cost and complexity of
developing these multi-tier services, resulting in services that can be
rapidly deployed and easily enhanced as the enterprise responds to
competitive pressures.
The Java 2 platform, Enterprise Edition (J2EE) achieves these benefits by
defining a standard architecture that is delivered as the following
elements:
J2EE Platform - A standard platform for hosting J2EE applications, specified
as a set of required APIs and policies.
J2EE Compatibility Test Suite - A suite of compatibility tests for verifying
that a J2EE platform product is compatible with the J2EE platform standard.
J2EE Reference Implementation - A reference implementation for demonstrating
the capabilities of J2EE and for providing an operational definition of the
J2EE platform.
Sun BlueprintsTM Design Guidelines for J2EE - Guidelines that describe a
standard programming model for developing multi-tier, thin-client
applications.
The following sections of this document describe each of these elements in
greater detail.

What's J2EE? ;-)
