Kotlin for Enterprise Applications using Java EE

Kotlin came from the industry, not academia, with the aim to solve programmers’ difficulties and operational challenges. This book is all about making Kotlin and Java EE work in unison to build enterprise-grade application. With Java EE API, Kotlin can be used to create services that are scalable, maintainable with just a few lines of logical code.

---

Build Java Enterprise Applications and learn how Kotlin makes it easier to code them using components like JSF 2.3, Enterprise JavaBeans (EJB) 3.2, Contexts and Dependency Injection (CDI) 2.0, the Java API for WebSockets, JAX-RS 2.1, Servlet 4.0.

Key Features

An in-depth guide updated with all the latest features of Kotlin 1.2 and Java EE 8
Build microservices in Java EE with the help of Kotlin use cases
Explore coroutines, garbage collection, multithreading, memory management and more

Book DescriptionKotlin was developed with a view to solving programmers’ difficulties and operational challenges. This book guides you in making Kotlin and Java EE work in unison to build enterprise-grade applications. Together, they can be used to create services of any size with just a few lines of code and let you focus on the business logic.

Kotlin for Enterprise Applications using Java EE begins with a brief tour of Kotlin and helps you understand what makes it a popular and reasonable choice of programming language for application development, followed by its incorporation in the Java EE platform. We will then learn how to build applications using the Java Persistence API (JPA) and Enterprise JavaBeans (EJB), as well as develop RESTful web services and MicroServices. As we work our way through the chapters, we’ll use various performance improvement and monitoring tools for your application and see how they optimize real-world applications. At each step along the way, we will see how easy it is to develop enterprise applications in Kotlin. By the end of this book, we will have learned design patterns and how to implement them using Kotlin.
