Java EE 8 Development with Eclipse - Third Edition

By: Ram Kulkarni

Overview of this book

Java EE is one of the most popular tools for enterprise application design and development. With recent changes to Java EE 8 specifications, Java EE application development has become a lot simpler with the new specifications, some of which compete with the existing specifications. This guide provides a complete overview of developing highly performant, robust and secure enterprise applications with Java EE with Eclipse. The book begins by exploring different Java EE technologies and how to use them (JSP, JSF, JPA, JDBC, EJB, and more), along with suitable technologies for different scenarios. You will learn how to set up the development environment for Java EE applications and understand Java EE specifications in detail, with an emphasis on examples. The book takes you through deployment of an application in Tomcat, GlassFish Servers, and also in the cloud. It goes beyond the basics and covers topics like debugging, testing, deployment, and securing your Java EE applications. You'll also get to know techniques to develop cloud-ready microservices in Java EE.

Eclipse MicroProfile


Microservices can be built with thecurrent JEE specification (JEE 8). However, there are certain specifications within JEE that are more important for developing microservices, such as JAX-RS (for RESTful Web Services) and JSON-P (for processing JSON data). So, a group of organizations has come together to create specifications for developing and running microservices, which are categorized as MicroProfile. Many of the specifications under MicroProfile are already part of the JEE specification (such as JAX-RS and JSON-P), but some are new specifications, such as for configuring and monitoring microservices.

The group has come up with two profiles so far. Each MicroProfile-compliant implementation is expected to implement each specification in the supported profile. This ensures that a microservice created with a particular profile runs on all Microprofile implementations supporting that profile. At the time of writing this chapter, the group has come up with two profiles...
