The Jakarta EE Platform Specification: Final Release

Doing Jakarta EE development? Learning how to use the Jakarta EE Platform? If so, then the right compendium to have by your side is the Jakarta EE Platform Specification.

Enterprises today need to extend their reach, reduce their costs, and lower the response times of their services to customers, employees, and suppliers.

Typically, applications that provide these services must combine existing enterprise information systems (EISs) with new business functions that deliver services to a broad range of users. The 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 the enterprise.
• Reliable and scalable, to ensure that business transactions are accurately and promptly processed.

In most cases, enterprise services are implemented as multitier __ applications. The middle tiers integrate existing EISs with the business functions and data of the new service. Maturing web technologies are used to provide first tier users with easy access to business complexities, and
eliminate or drastically reduce user administration and training.

The Jakarta(TM) EE Platform reduces the cost and complexity of developing multitier, enterprise services. Jakarta EE applications can be rapidly deployed and easily enhanced as the enterprise responds to competitive pressures. Jakarta EE achieves these benefits by defining a standard architecture with the following elements:

• Jakarta EE Platform - A standard platform for hosting Jakarta EE applications.
• Jakarta EE Compatibility Test Suite - A suite of compatibility tests for verifying that a Jakarta EE platform product complies with the Jakarta EE platform standard.
• Jakarta Compatible Implementations - Certified implementations for building and deploying Jakarta EE applications.

This document is the Jakarta EE platform specification. It sets out the requirements that a Jakarta EE platform product must meet.

There is only one source of truth for all questions pertaining to Jakarta EE based development: the specification document. Every Java developer should have a copy of it by their side.
