Introducing Jakarta EE CDI
Discover the Jakarta EE Contexts and Dependency Injection (CDI 2.0) framework which helps you write better code through the use of well-defined enterprise Java-based components and beans (EJBs). If you have ever wanted to write clean Java EE code, this short book is your best guide for doing so: you will pick up valuable tips along the way from your author's years of experience teaching and coding. Introducing Jakarta EE CDI covers CDI 2.0 in detail and equips you with the theoretical underpinnings of Java EE, now Jakarta EE. This book is packed with so much that by the end of it, you will feel confident to use your new-found knowledge to help you write better, readable, maintainable, and long-lived mission-critical software. What You Will Learn Write better code with the Jakarta EE Contexts and Dependency Injection (CDI) framework Work with the powerful, extensible, and well-defined contextual life cycle for components Use CDI’s mechanism for decoupling application components through a typesafe event API Build typesafe interceptors for altering the behaviour of components at runtime Harness the well-defined qualifier system for easy isolation of beans Convert almost any valid Java type to a CDI managed bean with CDI’s producer mechanism Who This Book Is For Experienced enterprise Java, Java EE, or J2EE developers who may be new to CDI or dependency injection.

Jakarta EE for Java Developers
Develop Enterprise Systems on Cloud Infrastructure Using a Rich Java Ecosystem. KEY FEATURES ● Every chapter and concept is illustrated through the use of the Jakarta Project. ● Extensive hands-on demonstration of Jakarta EE specifications and capabilities. ● Practical examples of securing Java applications with Jakarta Security are provided. DESCRIPTION This book provides a practical introduction to Enterprise Java Edition, Jakarta EE, including detailed features and capabilities. Equipped with numerous projects, each chapter demonstrates Jakarta EE capabilities with clean coding. The book starts with an introduction to Jakarta EE and its architecture. This will help to create a project using the Jakarta Servlet and exposure of an HTTP endpoint. The CDI is then used to inject dependencies, work with events asynchronously, and interact with CDI interceptors. Then, in the RESTful style, it can help to create a Jakarta RESTful resource to expose HTTP endpoints. We then investigate the Jakarta Enterprise Bean, which teaches us how to manage transactions and schedule tasks. The Jakarta Persistence is then used to integrate an application into a relational database, and the Jakarta Message is used to create an application using the Message Oriented Middleware (MOM). In terms of security, we use Jakarta Security to secure the endpoint of a Jakarta application. By the end of this book, the reader will be able to set up a Jakarta project and write applications that expose HTTP endpoints, integrate with a database, and deal with authentication and authorization. WHAT YOU WILL LEARN ● Create and use Servlets to build applications. ● Get to know CDI and practice how to create the CDI Interceptor and Decorator. ● Learn to build RESTful services and make use of Jakarta Enterprise Bean in your application. ● Use Jakarta Servlet and Jakarta RESTful to expose HTTP endpoints. ● Create a relational database-integrated application. ● Use authentication and authorization to build a secure application.
