Overview of this book

Jakarta EE stands as a robust standard with multiple implementations, presenting developers with a versatile toolkit for building enterprise applications. However, despite the advantages of enterprise application development, vendor lock-in remains a concern for many developers, limiting flexibility and interoperability across diverse environments. This Jakarta EE application development guide addresses the challenge of vendor lock-in by offering comprehensive coverage of the major Jakarta EE APIs and goes beyond the basics to help you develop applications deployable on any Jakarta EE compliant runtime. This book introduces you to JSON Processing and JSON Binding and shows you how the Model API and the Streaming API are used to process JSON data. You’ll then explore additional Jakarta EE APIs, such as WebSocket and Messaging, for loosely coupled, asynchronous communication and discover ways to secure applications with the Jakarta EE Security API. Finally, you'll learn about Jakarta RESTful web service development and techniques to develop cloud-ready microservices in Jakarta EE. By the end of this book, you'll have developed the skills to craft secure, scalable, and cloud-native microservices that solve modern enterprise challenges.

Authentication mechanisms

Authentication mechanisms provide a way for the user to provide their credentials so that they can be authenticated against an identity store.

The Jakarta EE Security API provides support for the HTTP Basic authentication mechanism provided by most browsers, as well as form authentication, which is the most common authentication mechanism where users provide their credentials via an HTML form.

Form authentication by default submits a form to the security servlet provided by the Jakarta EE implementation. If we need more flexibility or to better align with other Jakarta EE technologies, the Security API provides custom form authentication as well, which allows us as application developers to have more control over how to authenticate users attempting to access our application.

Basic authentication mechanism

A basic authentication mechanism can be achieved by annotating the resource as secure (i.e, a servlet or RESTful web service) with the @BasicAuthenticationMechanismDefinition...
