Web development is still one of today's most popular, active, and important programming and development activities. From a single web page to an e-commerce-enabled web site to a fully-fledged web application, the Java programming language and its frameworks allow you great flexibility and productivity for your web application development. Learn Java for Web Development teaches web developers who are new to Java key skills, Java-based languages, and frameworks to build simple or complex web sites and applications. As soon as you pick up this book, Vishal Layka's experience guides you on a very practical learning and building journey. You will learn the Java nuts and bolts necessary to build a simple "HelloWorld" Java (native) application, as well as a "HelloWorld" Java-based web application example that utilizes servlets and Java Server Pages (JSPs). Over the course of the book, you'll learn more about servlets and JSPs and delve into Java Server Faces (JSFs) and the expression language found in each of these by applying them in a real-world case study—a book store e-commerce application. Then you’ll build your web application using Apache Struts2 and the Spring MVC framework. The book concludes by exploring the web application that you've built and examining industry best practices and how these might fit with your application, as well as covering alternative Java Web frameworks like Groovy/Grails and Scala/Play 2. You also can explore the basics of Java, Groovy, and Scala in the book’s appendices. While reading this book, you'll see all this in action and you can use it as a starting point for further Java web development. Study and experiment with the many source code examples, and later apply them to your own web application building endeavors and 2:00 AM challenges.

Beginning Scala, Second Edition takes a down-to-earth approach to teaching Scala that leads you through simple examples that can be combined to build complex, scalable systems and applications. This book introduces you to the Scala programming language, its object-oriented and functional programming characteristics, and then guides you through Scala constructs and libraries that allow you to assemble small components into high-performance, scalable systems. You will learn why Scala is judiciously used for critical business applications by leading companies such as Twitter, LinkedIn, Foursquare, the Guardian, Morgan Stanley, Credit Suisse, UBS, and HSBC. Scala is a multi-paradigm programming language that combines both functional and object-oriented features. Moreover, this highly scalable language lends itself well to building cloud-based/deliverable Software as a Service (SaaS) online applications.

Learn the latest version of Scala through simple, practical examples. This book introduces you to the Scala programming language, its object-oriented and functional programming characteristics, and then guides you through Scala constructs and libraries that allow you to assemble small components into high-performance, scalable systems. Beginning Scala 3 explores new Scala 3 language features such as Top-level declarations, Creator applications, Extension methods to add extra functionality to existing types, and Enums. You will also learn new ways to manipulate types via Union types, intersection, literal, and opaque type aliases. Additionally, you'll see how Implicits are replaced by given and using clauses. After reading this book, you will understand why Scala is judiciously used for critical business applications by leading companies such as Twitter, LinkedIn, Foursquare, the Guardian, Morgan Stanley, Credit Suisse, UBS, and HSBC and you will be able to use it in your own projects. You will: Get started with Scala 3 or Scala language programming in general Understand how to utilitze OOP in Scala Perform functional programming in Scala Master the use of Scala collections, traits and implicits Leverage Java and Scala interopability Employ Scala for DSL programming Use patterns and best practices in Scala.

Web frameworks are playing a major role in the creation of today's most compelling web applications, because they automate many of the tedious tasks, allowing developers to instead focus on providing users with creative and powerful features. Java developers have been particularly fortunate in this area, having been able to take advantage of Grails, an open source framework that supercharges productivity when building Java–driven web sites. Grails is based on Groovy, which is a very popular and growing dynamic scripting language for Java developers and was inspired by Python, Ruby, and Smalltalk. Beginning Groovy, Grails and Griffon is the first introductory book on the Groovy language and its primary web framework, Grails.  Griffon is also covered. While Grails is the Web framework for building Groovy Web applications, Griffon is the deskop framework for building desktop Groovy applications.  Could Groovy be the new Java?  It's light, fast and free (open source).  This book gets you started with Groovy, Grails and Griffon, and culminates in the example and possible application of some real–world projects. You follow along with the development of each project, implementing and running each application while learning new features along the way.
