This chapter describes the benefits of the framework and how to build screens in the sample application using Spring MVC: a no-form controller, two form controllers, and a Spring HTTP interceptor.

This article describes how to use dependency injection with the Spring Framework.

Java’s original security architecture was designed to facilitate the execution of software from remote systems while simultaneously preventing downloaded code from performing unauthorized operations on host machines. The sandbox model of the Java Development Kit (JDK) 1.0’s security architecture was found to be too restrictive; therefore the model was modified so that remote code could be allowed as trusted code. In the Java 2 platform, also known as JDK 1.2, the notion of trusted code was removed and security control mechanisms were implemented that could be applied to both application and applet code so the code could be run with configurable trust. Creating applications in Java does not guarantee that they are secure. Java developers need to understand and incorporate the new Java security architecture into their development process to make certain their applications are secure. This article looks at the implementation of the new architecture and the new mechanisms provided for ensuring security for Java code. It details the motivation for the security changes in a security architecture, gives a general overview of the architecture added, and then looks at some of the details of the mechanisms either changed or provided by the new architecture.

The java double-check singleton pattern is not thread safe and can’t be fixed. In this article, Dr. Alexey Yakubovich provides an implementation of the Singleton pattern that he claims is thread-safe.

This articlel shows a simple technique that actually shows how objects are created and garbage collected at runtime. Using this technique you can properly select the best garbage collection options for your application.

XPath expressions are much easier to write than detailed Document Object Model (DOM) navigation code. When you need to extract information from an XML document, the quickest and simplest way is to embed an XPath expression inside your Java program. Java 5 introduces the javax.xml.xpath package, an XML object-model independent library for querying documents with XPath.

Validation reports whether a document adheres to the rules specified by the schema. Different parsers and tools support different schema languages such as DTDs, the W3C XML Schema Language, RELAX NG, and Schematron. Java 5™ adds a uniform validation Application Programming Interface (API) that can compare documents to schemas written in these and other languages. Learn about this XML validation API.

Gradle is proposed as a next-generation build solution. Gradle combines the flexibility of Groovy builds with a powerful domain specific language (DSL) that configures a rich set of classes. This allows to easily develop a non-standard build for any project, according to its needs, or to fall back to a more traditional “convention over configuration” approach also fully supported by the tool. This article presents what may ultimately be Groovy’s killer app.

If Scala is a fully JVM-compatible language, then you should be able to use it in various "real-world" environments such as one in which you build servlets and other Web applications. In this article, the author explores using Scala in a servlet environment.
