Overview of this book

The demand for modern and high performing web enterprise applications is growing rapidly. No more is a basic HTML frontend enough to meet customer demands. This book will be your one-stop guide to build outstanding enterprise web applications with Java EE and Angular. It will teach you how to harness the power of Java EE to build sturdy backends while applying Angular on the frontend. Your journey to building modern web enterprise applications starts here! The book starts with a brief introduction to the fundamentals of Java EE and all the new APIs offered in the latest release. Armed with the knowledge of Java EE 8, you will go over what it's like to build an end-to-end application, configure database connection for JPA, and build scalable microservices using RESTful APIs running in Docker containers. Taking advantage of the Payara Micro capabilities, you will build an Issue Management System, which will have various features exposed as services using the Java EE backend. With a detailed coverage of Angular fundamentals, the book will expand the Issue Management System by building a modern single page application frontend. Moving forward, you will learn to fit both the pieces together, that is, the frontend Angular application with the backend Java EE microservices. As each unit in a microservice promotes high cohesion, you will learn different ways in which independent units can be tested efficiently. Finishing off with concepts on securing your enterprise applications, this book is a handson guide for building modern web applications.

Learning to use the new features of Payara Micro

Payara Micro takes a new approach to deploying and running Java applications. It also comes with automatic and elastic clustering and takes into consideration modern day approaches, such as Docker containers. The Payara Micro executable itself is less than 70 MB and is a self-contained JAR. This JAR can be used to generate an Uber JAR or start a micro instance with the application deployed to it. Some of the capabilities that Payara offers are:

  • Embedded servers
  • Uber JAR approach
  • Deploying and running an application using the Payara JAR executable
  • Automatic clustering

This capabilities can be briefly explained as follows:

  • Embedding server: This can be done by using the fish.payar.micro package, which offers APIs for bootstrapping a micro instance programmatically with a single line:
        PayaraMicro.bootstrap();
  • Uber JAR...
