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.

Chapter 15: Putting it All Together

Jakarta JSON Processing

In the following sections, we will discuss how to process JSON data using the two APIs provided by Jakarta JSON Processing, namely the Model and Streaming APIs. We will also discuss how to retrieve values from JSON data using JSON Pointer, as well as how to partially modify JSON data via JSON Patch.

The JSON Processing Model API

The JSON Processing Model API allows us to generate an in-memory representation of a JSON object. This API is more flexible than the Streaming API discussed later in this chapter. However, it is slower and requires more memory, which can be a concern when handling large volumes of data.

Generating JSON data with the Model API

At the heart of the JSON Processing Model API is the JsonObjectBuilder class. This class has several overloaded add() methods that can be used to add properties and their corresponding values to the generated JSON data.

The following code sample illustrates how to generate JSON data using the Model...
