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 servlets using annotations


So far, we have seen declarative syntax for specifying security constraints; that is, by specifying <security-constraint> in web.xml. However, security constraints can also be specified using Java annotations, specifically for servlets. In this section, we will create AdminServlet and secure it with annotations. Follow the steps in the previous section to import the CourseManagementJDBC project from Chapter09, but rename it CourseManagementJDBC-SecureAnnotations, and import it into the workspace. Then, add only <login-config> in web.xml, but do not specify <security-constraint>:

  <login-config>
    <auth-method>FORM</auth-method>
    <form-login-config>
      <form-login-page>/login.jsp</form-login-page>
      <form-error-page>/login-error.jsp</form-error-page>
    </form-login-config>
  </login-config>

Make sure you have copied login.jsp and login-error.jsp, as described in the...
