Representational State Transfer, also known as REST, is a style of software architecture defined by a collection of architectural principles. REST is applied specifically to such distributed systems as the Web, and stipulates mechanisms for defining and accessing resources. The term, originally described in a dissertation by Roy Fielding, often is used to describe any framework that transmits data over a protocol, such as HTTP, without additional semantic layers or session management.The

BackgroundIn June 2000, Microsoft announced both the .NET platform and a new programming language called C#. C# is a strongly-typed object-oriented language designed to give the optimum blend of simplicity, expressiveness, and performance. The .NET platform is centered around a Common Language Runtime (similar to a JVM) and a set of libraries which can be exploited by a wide variety of languages which are able to work together by all compiling to an intermediate language (IL). C# and .NET

The Java developer community has been seeking a modular component framework and model since Java first appeared in the mid 1990s. The JavaBeans framework was billed as a programming and deployment mechanism that would compete with ActiveX as a component technology and that could be consumed in component-based development environments, much like Visual Basic. JavaBeans, we were told, would be easily packaged using the JAR format and distributed and deployed wherever we wanted, fulfilling Sun's

There is perhaps no area of programming tools where competition is as intense as in the Java IDE market. Even though there are only four primary players -- Eclipse, NetBeans, IntelliJ IDEA, and Oracle JDeveloper (Rational and CodeGear JBuilder build on Eclipse) -- all vendors except Oracle watch their competitors intently and rush to add new differentiating features. (Oracle's product is primarily aimed at internal use and at buyers of the company's Fusion Middleware stack.) The competition i

Signs that unit testing has hit a wall include the high-profile collapse of Agitar, which was known widely for a good, if expensive unit-testing product. CEO Jerry Rudisin told the SD Times that Agitar's collapse (it was bought by McCabe Software in June) was due simply to the fact that "unit testing hasn't taken off as a mainstream practice." Joe Ponczak, who heads up Condign Software, the makers of automated unit test generation tools and metrics dashboards, says he believes the Agitar fail

Developing a RESTful web application in Java is always not as easy compared with PHP. There are a number of REST frameworks for Java that you may want to use to develop REST web application.Restlet is a lightweight REST framework for Java, which features,Core REST concepts have equivalent Java classes (UniformInterface, Resource, Representation, Connector for example).Suitable for both client-side and server-side web applications. The innovation is that that it uses the same API, re

This is Part Four of a series of articles on Java.next. In Part Four, I will begin to explore how the Java.next languages (JRuby, Groovy, Clojure, and Scala) deal with concurrency. Concurrency is a big topic, so I will subdivide it, narrowing my focus in this part to how the Java.next languages support immutability.Why concurrency?Over the last decade, most programmers have written code with little concern for concurrency. Often this has caused problems later, when programs needed to be

One of the things that I most liked about ActionScript when I first began to use it was how easy it was to pick up after using Java for several years. I have blogged about some of the similarities Java and ActionScript share, but there are also some differences (such as ActionScript's support for switching on Strings). In this brief blog entry, I will demonstrate one subtle difference in behavior in ActionScript from what I am used to from years of C++ and Java experience.While ActionScri

While some portions of forthcoming Java SE 7 still appear to be controversial, the JMX 2 portion (JSR-255) of Java SE 7 seems to be solidifying nicely. In this blog entry, I will look at some of the new JMX querying capabilities in JMX 2 such as the JMX Query Language.JMX Specification Lead Eamonn McManus has posted several blog entries on JMX 2 including JMX Namespaces Now Available in JDK 7, Dropping Proposed Features from the New JMX API, and Playing with the JMX 2.0 API.
