Lift is a web application development framework that enables the building of web applications in the Scala programming language. Because it is powered by Scala, Lift can be deployed to any Java™ Servlet container such as Tomcat or Jetty, and can make use of both Java and Scala libraries and APIs. In June 2010, Lift 2.0 became available, and it boasts an impressive array of new features and highlights. This article describes many of these features and explains how they can benefit you in the development of your own web applications.

Lift is a free, open source web application development framework for building powerful, interactive, and dynamic applications using the Scala programming language. Scala is purely object-oriented, but, uniquely, it also has support for functional programming, giving you access to features such as anonymous functions, nested functions, curry functions, and higher-order functions. Scala runs in a Java Virtual Machine (JVM), making it compatible with Java applications and libraries. These traits mean that web applications powered by Lift can use both Scala and Java class libraries. In addition, Lift applications are packaged as Web Application Archive (WAR) files and can be deployed to any web application server that supports the Servlet 2.4 specification, including Apache Tomcat 5.5 and later.

The Dojo toolkit is a JavaScript library that makes the process of building large JavaScript-based Rich Internet Applications (RIAs) much simpler. With a wide range of features—from DOM querying and manipulation, Asynchronous JavaScript and XML (Ajax) request handling, excellent object-orientation support, and a full user interface widget library (Dijit)—Dojo is an excellent library to use to build a dynamic and interactive web application. In this tutorial, learn about many of the concepts of Dojo and the Dijit widget library through the development of a fully featured sample application, a contact manager system. This application lets a user browse, create, edit, and remove contacts (and contact groups) from a MySQL database. PHP is used on the server side to communicate with the database, with Dojo and the Dijit component library providing a rich, Ajax-powered user interface. The final result is a powerful web application that you can use as a foundation for your own RIAs.

The third and final part of my IBM developerWorks article series on the Dojo Toolkit was published today. It covers the Dijit component framework that allows you to build rich user interfaces in a declarative or programmatic way. This article introduces you to the various UI widgets available, and shows you the different ways of using them in your applications. It also introduces you to using Dijit to layout your application, and the DojoX extension library.

The Dojo toolkit lets Web application developers create Rich Internet Applications by offering a wide variety of features that save development time and effort. From DOM helpers and Ajax to a full-blown widget library and object-orientation features, Dojo includes virtually everything you need to build large-scale Asynchronous JavaScript and XML (Ajax)-powered Web applications. If the functions you are looking for are not included in Dojo itself, it’s highly likely that you can find it in DojoX, a repository of extensions and experimental features that are not included in the Base or Core modules of the toolkit. In Part 3 of this three-part series on developing rich web-based applications using the Dojo toolkit, learn about the Dijit rich user interface component framework, which lets you build powerful interfaces with minimal effort.

Dijit is the Dojo Toolkit’s user interface library of rich components. These components are fully theme-able, and can be declared either declaratively using HTML-style tags or programmatically using JavaScript. This section provides a brief explanation of Dijit, explains the components it has to offer, and describes the various themes that are available out of the box.
