Developing Middleware in Java EE 8

Use Java features such as JAX-RS, EJBs, and JPAs to build powerful middleware for newer architectures such as the cloud

Key Features

• Explore EJBs to build middleware solutions for enterprise and distributed applications
• Understand middleware designs such as event-based and message-driven web services
• Learn to design and maintain large-scale systems and vendor disputes

Book Description

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.

What you will learn

• Implement the latest Java EE 8 APIs and manage dependencies with CDI 2.0
• Perform CRUD operations and access databases with JPA 2.1
