Kotlin for Enterprise Applications using Java EE

By: Raghavendra Rao K

Overview of this book

Kotlin 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.

Introduction to JSF

JSF is a component-based, server-side Java framework for developing user interfaces. It is the primary web framework in Java EE and includes the MVC model and the template framework.

It aims to simplify the frontend aspect of Java Enterprise applications and accelerate user interface development. It uses a component-based model to build the user interface. It defines a UI component model, which is bound to a well-defined request processing model, a POJO (Plain Old Java Object), in an enterprise application. This allows JSP custom libraries to handle those UI components and provides a mechanism to extend the standard UI components.

JSF saves the state information of the UI components and repopulates them during the display, since the state of the components lives beyond the lifespan of the HTTP request.

JSF operates by providing functionalities such as data...
