In Pro CDI 2 in Java EE 8, use CDI and the CDI 2.0 to automatically manage the life cycle of your enterprise Java, Java EE, or Jakarta EE application’s beans using predefined scopes and define custom life cycles using scopes. In this book, you will see how you can implement dynamic and asynchronous communication between separate beans in your application with CDI events. The authors explain how to add new capabilities to the CDI platform by implementing these capabilities as extensions. They show you how to use CDI in a Java SE environment with the new CDI initialization and configuration API, and how to dynamically modify the configuration of beans at application startup by using dynamic bean building. This book is compatible with the new open source Eclipse Jakarta EE platform and tools. What You Will Learn Use qualifier annotations to inject specific bean implementations Programmatically retrieve bean instances from the CDI container in both Java SE and Java EE when injecting them into an object isn’t possible Dynamically replace beans using the @Alternative annotation to, for example, replace a bean with a mock version for testing Work with annotation literals to get instances of annotations to use with the CDI API Discover how scopes and events interact Who This Book Is For Those who have some experience with CDI, but may not have experience with some of the more advanced features in CDI.

Java developers typically go through four "stages" in mastering Java. In the first stage, they learn the language itself. In the second stage, they study the APIs. In the third stage, they become proficient in the environment. It is in the fourth stage --"the expert stage"-- where things really get interesting, and Java Enterprise Best Practices is the tangible compendium of experience that developers need to breeze through this fourth and final stage of Enterprise Java mastery.Crammed with tips and tricks, Java Enterprise Best Practices distills years of solid experience from eleven experts in the J2EE environment into a practical, to-the-point guide to J2EE.Java Enterprise Best Practices gives developers the unvarnished, expert-tested advice that the man pages don't provide--what areas of the APIs should be used frequently (and which are better avoided); elegant solutions to problems you face that other developers have already discovered; what things you should always do, what things you should consider doing, and what things you should never do--even if the documentation says it's ok.Until Java Enterprise Best Practices, Java developers in the fourth stage of mastery relied on the advice of a loose-knit community of fellow developers, time-consuming online searches for examples or suggestions for the immediate problem they faced, and tedious trial-and-error. But Java has grown to include a huge number of APIs, classes, and methods. Now it is simply too large for even the most intrepid developer to know it all. The need for a written compendium of J2EE Best Practices has never been greater.Java Enterprise Best Practices focuses on the Java 2 Enterprise Edition (J2EE) APIs. The J2EE APIs include such alphabet soup acronyms as EJB, JDBC, RMI, XML, and JMX.
