This article looks at web programming via Haskell. Web programming is supported in various ways, from low-level libraries for the basic operations like communicating over http and creation of html documents, up to sophisticated frameworks for building apps and performant web servers for running the apps. January’s article will look at the frameworks, primarily Yesod. This article will look at Fay, which is a Haskell alternative to CoffeeScript.

The protocol used for exchanging files on the Web is stateless, but maintaining state is essential for most websites. To maintain state, one option that Web developers have is to use cookies. This article provides a technical background and real-world examples to help you understand how cookies work and how to test systems that employ cookies. The amazon.com website is used as a real-world example to demonstrate cookie testing techniques.

jQuery is emerging as the JavaScript library of choice for developers looking to ease their creation of dynamic Rich Internet Applications. As browser-based applications continue to replace desktop applications, the use of these libraries will only continue to grow. Get to know jQuery in this series of articles and learn how you can implement it in your own Web application projects.

This second article in the jQuery series looks at how to add more interaction to any Web site to create a dynamic Rich Internet Application. Learn how jQuery utilizes a combination of events produced by user interaction, information gathered from the Web site itself, and the ability to change the look and feel of the application without reloading to create these RIAs quickly and easily.

The jQuery UI package aims to create a well-defined and reliable set of user interface widgets that you can reuse within your own Web applications. The goal is to provide well-tested widgets that go beyond those available in HTML Input elements, and ease the work of all user interface developers.

The Java Platform has evolved into a solid and mature enterprise application platform. One of the signs of a mature application platform is that there are a lot of spin-off techniques and options to integrate with other techniques. This article will go into detail about how to write JEE applications with Grails, a spin-off of traditional JEE application development, and Flex, a different technique that can be used with Java. Both frameworks can be highly productive. Combining the two frameworks holds the promise of building rich internet frontends to J2EE applications while retaining the high productivity.

XForms adopts the familiar XPath expression language for two purposes. First, it uses it as a query language for addressing and identifying fields within the form and the user-submitted data. In particular, it uses XPath expressions to bind input controls to particular parts of the form's data model. Second, it uses XPath as its basic calculation language for output, bind, and setvalue elements. The focus of this article is mostly on the second usage, though some of these functions are useful for binding as well.
