Developing Middleware in Java EE 8

Overview of this book

Middleware is the infrastructure in software based applications that enables businesses to solve problems, operate more efficiently, and make money. As the use of middleware extends beyond a single application, the importance of having it written by experts increases substantially. This book will help you become an expert in developing middleware for a variety of applications. The book starts off by exploring the latest Java EE 8 APIs with newer features and managing dependencies with CDI 2.0. You will learn to implement object-to-relational mapping using JPA 2.1 and validate data using bean validation. You will also work with different types of EJB to develop business logic, and with design RESTful APIs by utilizing different HTTP methods and activating JAX-RS features in enterprise applications. You will learn to secure your middleware with Java Security 1.0 and implement various authentication techniques, such as OAuth authentication. In the concluding chapters, you will use various test technologies, such as JUnit and Mockito, to test applications, and Docker to deploy your enterprise applications. By the end of the book, you will be proficient in developing robust, effective, and distributed middleware for your business.

Dependency Injection Using CDI 2.0

CDI (Contexts and Dependency Injection) is one of the most essential and powerful APIs in Java EE. With CDI, you can easily divide your application into separate components interacting with each other, avoiding all the hassles of managing your components, life cycles, calling JNDI, and any other redundant programmatic work. Although the initial goal of CDI was to provide an easy mechanism for tying the web layer to the data access layer, CDI now has a broader scope of usage and implementation scenarios. Let's take an overview of the key features that CDI provides to our middleware solution:

  • DI (Dependency Injection): A popular technique for supplying components with other components they depend on. CDI provides a declarative approach for defining components and their scope of life, and of course obtaining them back. Moreover, DI in...
