Key FeaturesRecipes to get you up-and-running with Java EE 8 application development Learn how to apply the major Java EE 8 APIs and specificationsImplement microservices and Reactive programming with Java EE 8Book Description
Java EE is a collection of technologies and APIs to support Enterprise Application development. The choice of what to use and when can be dauntingly complex for any developer. This book will help you master this. Packed with easy to follow recipes, this is your guide to becoming productive with Java EE 8.
You will begin by seeing the latest features of Java EE 8, including major Java EE 8 APIs and specifications such as JSF 2.3, and CDI 2.0, and what they mean for you.
You will use the new features of Java EE 8 to implement web-based services for your client applications. You will then learn to process the Model and Streaming APIs using JSON-P and JSON-B and will learn to use the Java Lambdas support offered in JSON-P. There are more recipes to fine-tune your RESTful development, and you will learn about the Reactive enhancements offered by the JAX-RS 2.1 specification.
Later on, you will learn about the role of multithreading in your enterprise applications and how to integrate them for transaction handling. This is followed by implementing microservices with Java EE and the advancements made by Java EE for cloud computing.
The final set of recipes shows you how take advantage of the latest security features and authenticate your enterprise application.
At the end of the book, the Appendix shows you how knowledge sharing can change your career and your life.

Foreword
It is a measure of the penetration, longevity, and quality of Java EE technology that in 2018 my friend Elder Moraes asked me to write the foreword for his book about Java EE 8. My personal involvement with Java EE goes back to the days preceding J2EE 1.4 in 2001. Since then, I have had the great honor of leading or co-leading the community teams that have developed JavaServer Faces and, later, servlet, two of the technologies Elder covers in this book. During that time, I tried to follow the model of servant-leader, and I think the result has been a very engaged community that has a real stake in the continued success of Java EE.When writing this foreword, I want to focus on four Cs: Curation, Cohesion, Current, and Completeness. So much has been written about Java EE over the years, and continues to be written, that the task of writing a book, particularly one in the useful "cookbook" format, involves a lot of curation. From the set of all possible things that people are doing with Java EE, which is vast, Elder has presented a curation of what he thinks are the most useful and essential ones. Elder is well positioned to decide what goes in and what stays out. Elder has been consulting and working with Java EE for nearly as long as I have, but from the more practical perspective of the user. Technical books that follow the cookbook pattern frequently suffer from a feeling of disjointness. Not this book. Elder has put a great deal of effort into ensuring cohesion. Over the years, the technologies of Java EE have sometimes been criticized for not being cohesive enough with each other. This is something Sun made a conscious effort to address starting with Java EE 6, and which Oracle continued on to Java EE 8. Elder has leveraged this effort to seek out and present the best way to leverage the synergy of all the technologies of Java EE 8 to maximum effect.The world outside Java EE has continued to evolve, and this has changed the way people use Java EE dramatically. The challenge for any architect on a multiyear software effort, with a service lifetime of at least a decade, is how to keep it maintainable even while the surrounding technology landscape changes. Elder has accounted for this with two excellent chapters about microservices and Docker. These two technologies provide a great complement to the power of Java EE, but also have numerous pitfalls. Elder helps you avoid the pitfalls while getting the most out of these current trends.
Finally, completeness. Many technology cookbooks stop short of providing "complete reference" sort of material, but Elder goes much deeper. It's almost to the point that the term "cookbook" does not do this book justice. Perhaps, a more correct label would be "complete restaurant management with supply chain logistics and a cookbook on top." Elder covers the current popular app servers on which people are running Java EE, continuous integration and pipelines, reactive programming, and more. Coming back to the curation point, it's all there, and in depth.
I hope you have success with Java EE and with its successor, Jakarta EE from the Eclipse Foundation.

Preface
Java EE is a mature platform that's widely used around the world. It is also a standard that has evolved through the hard work of individuals, vendors, groups leaders, and communities. It has a whole market and ecosystem around it, with millions of users, which also means a big and active community that is always willing to help it move forward.
For those reasons, the purpose of this book is to meet the needs of those professionals who depend on Java EE to deliver really awesome enterprise solutions, not only talking about real solutions for real problems, but also showing how to do it in a practical way.
The book starts with a quick overview of what Java EE and the improvements in version 8. Then, it takes you on a hands-on journey through the most important APIs.
You will learn how to use Java EE for server-side development, web services, and web applications. You will also take a look at how you can properly improve the security of your enterprise solutions.
No Java EE application is good enough if it doesn't follow the standards, and for that, you can count on the Java EE application servers. This book will teach you how to use the most important servers on the market and take the best they have to offer for your project.
From an architectural point of view, the book will cover microservices, cloud computing, and containers. Also, it will not forget to give you all tools for building a reactive Java EE application using not only Java EE features, but also Java core features such as lambdas and completable future.
The whole Java world is all about the community, so we will also show you how community-driven professionals can improve the results of their projects and even go to higher levels in their careers.
The book was based on a concept that I call "The Five Mistakes That Keep Java EE Professionals Away From Great Projects." I am ruining my career when I don't do the following things:
Keep myself up to date
Know the APIs (an overview of all of them and master the most important ones)
Know the most commonaly used Java EE application servers
Know advanced architectures
Share what I know
So, the book is a straight, practical, and helpful solution to each one of these mistakes. I can say with confidence that dealing with them properly can change the careers and lives of many developers around the world. I know because they've changed mine, for good.
Who this book is for
This book is made for developers who would like to learn how to meet real enterprise application needs using Java EE 8. They should be familiar with application development and need to have knowledge of least basic Java, the basic concepts of cloud computing, and web services.
The readers should want to learn how to combine a bunch of APIs in a secure and fast solution, and for this, they need to know how the APIs work and when to use each one.
What this book covers
Chapter 1, New Features and Improvements, explains the main changes to the Java EE 8 specification and what the reader can do with them. It also shows the new features and briefly explores the benefits of them. All these topics are supported by code examples.
Chapter 2, Server-Side Development, deep dives into the most important APIs and most commonly used features for server-side development. The readers here will go through real recipes for solving real problems.
Chapter 3, Building Powerful Services with JSON and RESTful Features, creates web services for different enterprise scenarios. Readers will go deep into the JAX-RS, JSON-P, and JSON-B APIs.
Chapter 4, Web- and Client-Server Communication, deals with the communication generated by web applications in a fast and reliable way using the latest Java EE 8 features, such as HTTP2 and Server Push.
Chapter 5, Security of Enterprise Architecture, gives the readers information on the tools using the best Java EE features to create secure architectures.
Chapter 6, Reducing the Coding Effort by Relying on Standards, describes the services and features that Java EE application servers give to the applications they host. Those features not only let the readers rely on a standard and build their application based on it, but also allow them to write less code, as they don't need to implement features that have been already implemented by the server.
Chapter 7, Deploying and Managing Applications on Major Java EE Servers, describes the use of each of the most commonly used Java EE application servers on the market, giving special attention to the way you deploy and manage them.
Chapter 8, Building Lightweight Solutions Using Microservices, makes you understand how microservice architectures work and how readers can easily use Java EE 8 to build microservice and/or break down their monoliths in order to implement this paradigm.
Continuous Delivery and Continuous Deployment are also described, as no successful microservice project is complete without a mature building and deployment process.
Chapter 9, Using Multithreading on Enterprise Context, describes the use of multithreading and concurrency when building enterprise applications.
Chapter 10, Using Event-Driven Programming to Build Reactive Applications, describes the use of Java EE 8 and core Java to create low-latency, efficient, and high-throughput applications.
Chapter 11, Rising to the Cloud – Java EE, Containers, and Cloud Computing, describes how to combine Java EE and containers to run applications on the cloud.
Appendix, The Power of Sharing Knowledge, describes how the community is vital for the whole Java EE ecosystem (even if readers don't know about it) and how they can improve their own daily work by joining the Adopt a JSR initiative.
It also describes how sharing knowledge is a powerful tool for improving their careers and what it has to do with Java EE (and it has everything to do with Java EE!).
To get the most out of this book
Readers should be familiar with application development and need to have at least basic knowledge of Java. Basic knowledge of cloud computing and web services are also assumed.
