Reuse is the Holy Grail that many IT shops search for to reap the benefits of lower development and maintenance costs. Read on and peel the layers of the portal onion, examining how each layer enables reuse of front-end components and infrastructure.

In this article, Bryon Jacob and Chris Berry continue their description of AtomServer, their implementation of a full-fledged Atom Store based on Apache Abdera.

In this article, Bryon Jacob and Chris Berry introduce AtomServer, their implementation of a full-fledged Atom Store based on Apache Abdera, which is now available as open source.

Create a RESTful Web service, which is defined as a Spring bean, using Apache CXF, an open source Web service framework. This article explores the features and benefits of using the Representational State Transfer (REST) architecture and illustrates the use of the REST API in CXF to easily develop a RESTful service.

Ganymede includes a number of new projects that introduce new technologies to the Eclipse platform. This three-part "Using Eclipse Ganymede to develop for the desktop, Web and mobile devices" tutorial series, covers the new Ganymede features supporting this type of development. In this part 2, we will take the personal organizer developed in Part 1, and modify it to use the new Rich Ajax Platform (RAP) to package and distribute the application on the Web.

Representational state transfer (REST) is a style of designing loosely coupled applications that rely on named resources rather than messages. The hardest part of building a RESTful application is deciding on the resources you want to expose. Once you've done that, using the open source Restlet framework makes building RESTful Web services a snap. This tutorial guides you step-by-step through the fundamental concepts of REST and building applications with Restlets.

Want to build numerous similar Web components without cutting and pasting code? Wicket could be the framework for you.

While virtualization provides many benefits, security can not be a forgotten concept in its application.

Ruby's Open Classes are powerful - but can easily be misused. This article looks at how to minimize the risk of opening classes, alternatives, and how other languages provide similar capabilities.

While increasingly more websites are utilizing AJAX, it is still difficult to develop complicated AJAX applications. This article explores how multithreading eases some of these issues

One of the most exciting things in Java right now is the work being done to get other programming languages onto the JVM. If you want to try something very different from Java, Lisp is a great option.

Patterns exist for virtually all common programming challenges, even one as simple as "how to traverse a collection of objects." The iterator pattern provides a consistent solution for something that programmers do daily.

Do you want to build your Web sites faster and cheaper, but still leverage industrial-strength technology? You can do just that using Grails and Apache Geronimo. Grails leverages the power of the dynamic language Groovy to accelerate your development. However, it runs on the Java Virtual Machine and leverages proven Java technologies. This makes it easy to take your Grails application to the next level by deploying it to Apache Geronimo, the premiere open source Java EE V5-certified application server. In this article, you will see how easy Grails can make Web development and how easy Geronimo can make Grails deployment. You will also see how a Grails application can leverage the resources and services provided by Geronimo.

In part two of this series, Wang Yu presents some surprising results of Java application scalability based on his experiences in a performance laboratory.

In this article, Stefan Tilkov explains some of the most common anti-patterns found in applications that claim to follow a "RESTful" design and suggests ways to avoid them.

It is easy to think that virtualization applies only to servers. In reality the recent resurgence of the concept is also being applied to networking, storage, and application infrastructure.

Refactoring is a well-accepted practice for improving existing code. Yet, how do you find the code that should be refactored, in a consistent and repeatable manner? This installment of Automation for the people explains how to use static analysis tools to identify code smells to refactor, with examples showing how to improve odiferous code.

No data format is harder to search than XML, but with the fairly recent introduction of the XQuery API, XML searches are now flexible and easy to perform. For Java™ programmers who work with XML documents using SAX, DOM, JDOM, JAXP, and more, the XQuery API for Java is a welcome addition to the programmer's toolkit. Now the power of XQuery is available to Java programmers without resorting to system calls or unwieldy APIs, all in a Sun-standardized package.

Thin client paradigm characterized by web applications is a kludge that needs to be repudiated. Old compromises are no longer needed and it's time to move the presentation tier to where it belongs.

As the complexity and sophistication of application and business logic within Web services increases, so does the risk associated with putting a corporation’s business intelligence “out there.” The purpose of this article is to create an awareness of the many aspects of Web services security, with an emphasis on the WS-Security framework.

In this article, Adrien Louis and Marc Dutoo discuss the differences and relative merits of using orchestration vs. routing in a typical ESB setup, and discuss various implementation options.

This article deals with the components that are together commonly referred to as Web services, which were originally designed for services that can be accessed over the Internet. You'll also see that many of the Web services components can be used with services that don't use the Internet and that only require a network connection.

In this article, learn about seven practices that can reduce overtime, cut costs, and speed up production on your software development project. Create a solid foundation for healthier development, and increase your chances of meeting deadlines with less stress.

Wildcards can be very confusing when it comes to generics in the Java™ language, and one of the most common mistakes is to fail to use one of the two forms of bounded wildcards ("? super T" and "? extends T") when needed. You've made this mistake? Don't feel bad, even the experts have, and this month Brian Goetz shows you how to avoid it.
