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 security API

The Security 1.0 API is a brand new API specification in Java EE 8 that provides a new programming model for securing enterprise applications. The security API version 1.0 is a reference implementation of JSR 375, the Java EE Security API specification. This specification is aimed at simplifying and supporting new security aspects for platform services, standardizing the way that we secure applications. The security API is annotation-driven and uses a lot of CDI and Expression Language (EL) to make the implementation easier.

The key features of the security API implementation include the following:

  • The IdentityStore mechanism
  • HttpAuthenticationMechanism
  • The SecurityContext interface

IdentityStore provides an implementation for storing user details, but other implementations are also out there, such as an embedded store, a database store, and the...
