Overview of this book

Jakarta EE stands as a robust standard with multiple implementations, presenting developers with a versatile toolkit for building enterprise applications. However, despite the advantages of enterprise application development, vendor lock-in remains a concern for many developers, limiting flexibility and interoperability across diverse environments. This Jakarta EE application development guide addresses the challenge of vendor lock-in by offering comprehensive coverage of the major Jakarta EE APIs and goes beyond the basics to help you develop applications deployable on any Jakarta EE compliant runtime. This book introduces you to JSON Processing and JSON Binding and shows you how the Model API and the Streaming API are used to process JSON data. You’ll then explore additional Jakarta EE APIs, such as WebSocket and Messaging, for loosely coupled, asynchronous communication and discover ways to secure applications with the Jakarta EE Security API. Finally, you'll learn about Jakarta RESTful web service development and techniques to develop cloud-ready microservices in Jakarta EE. By the end of this book, you'll have developed the skills to craft secure, scalable, and cloud-native microservices that solve modern enterprise challenges.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “As can be seen in the example, we generate an instance of JsonObject by invoking the add() method on an instance of JsonObjectBuilder.”

A block of code is set as follows:

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html;
      charset=UTF-8">
    <title>Login Error</title>
  </head>
  <body>
    There was an error logging in.
    <br />
    <a href="login.html">Try again</a>
  </body>
</html>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

package com.ensode.jakartaeebook.security.basicauthexample;
//imports omitted for brevity
@BasicAuthenticationMechanismDefinition
@WebServlet(name = "SecuredServlet", urlPatterns = {"/securedServlet"})
@ServletSecurity(
        @HttpConstraint(rolesAllowed = "admin"))
public class SecuredServlet extends HttpServlet {
  @Override
  protected void doGet(HttpServletRequest request,
    HttpServletResponse response) throws ServletException, IOException {
    response.getOutputStream().print(
      "Congratulations, login successful.");
  }
}

Any command-line input or output is written as follows:

appclient -client simplesessionbeanclient.jar

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Now that we have created a customer, our Customer List page displays a data table listing the customer we just created.”
