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.

Securing applications in GlassFish


We will use the Course Management application that we developed in Chapter 7, Creating JEE Applications with EJB, to add security features. Follow these steps to import projects:

  1. Create a new Eclipse workspace for this chapter.
  2. Copy all the projects in the source code folder for Chapter 7Creating JEE Applications with EJB, inside the with-maven folder, to the current workspace.
  3. Import all the projects into the new workspace (open the File | Import menu and then select Maven | Existing Maven Projects).

You should now have the following projects in your Eclipse workspace: CourseManagementMavenEAR, CourseManagementMavenEJBClient, CourseManagementMavenEJBs, and CourseManagementMavenWebApp. Let's now learn how to protect access to JSPs in a folder.

Protecting access to folders in web applications

To protect any resources in a web folder, you need to declare security constraints in web.xml. In the security constraints, you can declare URLs that are to be protected...
