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.

Jakarta Faces includes several features to make Faces pages work nicely with HTML5. Jakarta Faces support for HTML5 includes the ability to develop our Jakarta Faces pages in HTML5 without using Faces-specific tags, along with the ability to add arbitrary HTML5 attributes to our Jakarta Faces pages.

HTML5-friendly markup

Through the use of pass-through elements, we can develop our Faces pages using HTML5, as opposed to using Faces-specific tags. Using HTML5 to develop our pages has the advantage that we can preview how our page renders in the browser without having to deploy our application to a Jakarta EE runtime. We can simply open the page in a web browser.

To do this, we need to specify at least one of the element attributes using the jakarta.faces XML namespace. The following example demonstrates this approach in action:
