Murach’s Java Servlets and JSP (3rd Edition)
From the start, servlets and JSPs have been a training problem because web programming with them requires so many different skills and so much conceptual background. But the first edition of this book solved that training problem: It presented the critical skills in the right order with plenty of examples, allowing developers to master all the complexities in a manageable way.
Now, this improved and updated 3rd Edition makes it even easier and faster for you to learn. And to prove to yourself that you will master all the servlet and JSP skills that you need to develop e-commerce applications, you can download the book’s e-commerce website that ties all the skills together.

Who this book is for
This book is for anyone who wants to develop professional websites using Java servlets and JSPs. The only prerequisite is a basic understanding of the Java programming language, roughly equivalent to chapters 1 through 14 of our core Java book, Murach’s Java Programming. But you don’t need any web programming experience at all.
What you’ll learn in this book
Section 1: Get started right
In this section, you’ll learn:
- the concepts and terms that you need for Java web programming
- how to use the MVC pattern to get the most from JSPs and servlets
- how to use the NetBeans IDE for developing servlet and JSP applications more efficiently
- how to use the Tomcat web server that lets you use servlets and JSPs for web applications
By the time you’re through with this section, you’ll be ready to use the IDE to code and run servlets and JSPs on your own computer.
Section 2: The essential servlet and JSP skills
In this section, you’ll get a crash course in HTML and CSS, which are essential to the use of JSPs. Then, you’ll learn the skills for creating servlets and JSPs that you’ll use in almost every application. These chapters move from the simple to the complex as you learn how to work with servlets, JSPs, sessions, cookies, JavaBeans, Expression Language (EL), the JSP Standard Tag Library (JSTL), and custom JSP tags.
Section 3: The essential database skills
Here, you’ll learn how to use both JDBC (Java Database Connectivity) and JPA (Java Persistence API) to work with a database. Although this section focuses on the use of MySQL databases, JDBC and JPA can be used for working with any database management system, including Oracle and SQL Server.
Section 4: Advanced servlet and JSP skills
In this section, you’ll learn the advanced servlet and JSP skills that you will need for certain types of web applications. This includes the use of JavaMail, SSL, authentication, encryption, HTTP, listeners, and filters. Then, the last chapter in this section shows you how to use JavaServer Faces, which is an alternative to using JSPs.
Since the chapters in this section have been designed to work independently of each other, you can read them in any order you want. This makes it easy for you to learn new skills whenever you need them.
Section 5: The Music Store website
This section presents an e-commerce website that puts the skills in the first four sections into context. This downloadable application illustrates best practices and provides code that you can use in your own applications. Once you understand how this website works, you will have all the skills you need for creating your own web applications.
Why you’ll learn faster and better with this book
Like all our books, this one has features that you won’t find in competing books. Here, though, are a few of the features that are unique to this book:
- Chapter 2 shows how to use the MVC pattern (or Model 2 architecture) to get the most from JSPs and servlets. From that point on, you’ll use servlets when they’re appropriate and JSPs when they’re appropriate. As a result, you won’t waste your time learning how to use servlets for tasks that should be handled by JSPs, or vice versa.
- Chapter 3 shows how to use the NetBeans IDE with a Tomcat server to develop web applications on your own computer. By using this IDE, you’ll learn faster and better than you would without one. In contrast, most competing books let you figure this out on your own.
- Chapter 4 provides a crash course in HTML5 and CSS3. Since this is essential background for the use of JSPs, this means you won’t have to use a second book to figure out how HTML and CSS work.
- Like all of our books, this one includes dozens of examples that range from the simple to the complex. That way, you can quickly see how a feature works from the simple examples, but you’ll also see how the feature is used in more complex, real-world examples, including the complete e-commerce application that’s presented in section 5.
What’s new in this edition
- An improved instructional approach that starts by presenting the MVC pattern in chapter 2. That way, you will use the MVC pattern for all exercises and projects, and you won’t learn programming practices that you won’t or shouldn’t use on the job.
- New chapters on how to use JPA (Java Persistence API) for database programming, security skills that weren’t covered in the second edition, and JavaServer Faces (JSF).
- An improved Music Store website in two versions: one that uses JDBC and one that uses JPA.
- Technical enhancements throughout the book, thanks to co-author Michael Urban, who has a wealth of Java web programming experience.
What software you need
To create and use the web applications in this book, you need to install this software on your PC:
- Java SE
- NetBeans
- Tomcat
- MySQL
- MySQL Workbench
This software is available for Windows, Mac OS X, and Linux systems.
Although all of this software is free, it can be difficult to install and get started with it. So this book provides all the support you need for doing that if you’re working on a Windows or Mac system:
- Appendix A shows how to install the software on Windows systems.
- Appendix B shows how to install the software on Mac OS X systems
- Chapter 3 shows how to use NetBeans and Tomcat
If you’re using a Linux system, we assume that you’ll be able to install this software on your own. If not, you can use appendix B as a general guide and use the Internet to get any other information that you need.

What people have said about the previous editions
“This is an excellent tutorial that will painlessly teach you how to write complex web applications. I doubt that there is another book available that makes the subject this easy to understand.”
-- Thomas Paul, JavaRanch.com
"I love the layout, style, organization, thoroughness, ease of understanding, and overall excellence of the Murach books. They explain everything very clearly, step by step, in a mentor/instructor conversational style, and in a problem-solving context…. In short, I cannot recommend Murach’s Java Servlets and JSP (2nd Edition) enough. This book is a pleasure to read, and I’ve learned a ton, and solidified my knowledge and skills regarding Java web development.
“Get it. You’ll like it. It’s well worth the price tag."
--Jeff Salter, TheServerSide.com
"I have to admit I was a bit intimidated by JSP and servlets. But Murach’s treatment of the topic is excellent. It goes step-by-step, starting with simple examples, but the pace doesn’t feel overly slow. You always feel like you’re making good progress.... Overall a great book."
--Posted at an online bookseller
"I’ve read a lot of computer technology books, and rarely have I felt so solidly prepared as this one to transfer what I’ve learned into real projects."
--Posted at an online bookseller
"A very strong point your book has is putting crystal-clear comments on the left page, with short but realistic examples and a summary on the right. The idea is simple, but very efficient: it allowed me to progress at light speed and still proves to be very convenient when I need to refresh my memory within seconds. It makes me a more productive programmer. Very good index, too!"
--Xavier Mercier, Software Designer, Galway, Ireland
"I have been a developer for over 10 years in many different languages and usually for each language or topic I buy lots of books, most of which, sad to say, are fairly boring, overly complex, teach useless stuff, or are way too cluttered and disorganized to get the points across. Usually I find a couple of books that really stand out and become tattered and ragged with use. This is such a book."
--Posted at an online bookseller
"Every so often you find a technical book that is so superbly written you actually enjoy reading it, because you know you’re going to be able to understand and learn more each time you pick it up. From the start of this book, through to the end, I found myself feeling so glad I found this book and so grateful to the authors, because the care and skill with which it was written makes it very easy to read and understand."
--Posted at an online bookseller
“This book takes you through a well-structured learning journey of JSP, Servlets, and related technologies such as Netbeans, Tomcat and MySQL for developing complete web apps. The book has provided me with the skill and confidence to start building my own web-app.”
-- Posted at an online bookseller
"There is a line written on this book, ‘No other book teaches you so much, so fast, so thoroughly,’ and I must tell you that this is 100% correct. Congrats !! on coming up with this amazing work of yours.... Looking forward to more books on other languages as well."
--Ravi Nathani, Software Engineer Wireless and Multimedia Products

What if you don’t use the NetBeans IDE?
Because we use the NetBeans IDE throughout our Servlets and JSP book, the downloadable files are arranged in the directory and file structure that NetBeans requires.
However, you can use another IDE like Eclipse with this book. In that case, you’ll just need to convert the NetBeans directory and file structure so it’s appropriate for your IDE.
Below are the answers to the questions that have come up most often about this book. If you have any questions that aren't answered here, please email us. Thanks!
Whenever I run the SQLGateway application, I get an error that says “Unable to load authentication plugin 'caching_sha2_password' ”. How can I fix this?
This error is occurring because you have installed MySQL 8.0 or later. Unfortunately, the NetBeans projects for this book use Connector/J drivers that are designed to work with MySQL 5.x. The easiest way to fix this problem is to uninstall MySQL 8.0 and install an earlier version of MySQL such as MySQL 5.7.
Whenever I run an application that attempts to use a connection pool to get a connection to a database, the ConnectionPool class throws a NullPointerException and the application crashes. How can I fix this?
