"Apache Struts 2 is an elegant, extensible framework for creating enterprise-ready Java web applications. The framework is designed to streamline the full development cycle, from building, to deploying, to maintaining applications over time. Apache Struts 2 was originally known as WebWork 2. After working independently for several years, the WebWork and Struts communities joined forces to create Struts2. This new version of Struts is simpler to use and closer to how Struts was always meant to be. "

With proper mark-up/logic separation, a POJO data model, and a refreshing lack of XML, Apache Wicket makes developing web-apps simple and enjoyable again. Swap the boilerplate, complex debugging and brittle code for powerful, reusable components written w

qooxdoo is a comprehensive and innovative Ajax application framework. Leveraging object-oriented JavaScript allows developers to build impressive cross-browser applications. No HTML, CSS nor DOM knowledge is needed. It includes a platform-independent dev

"RCP applications in a web browser The Rich Ajax Platform lets you build rich, Ajax-enabled Web applications by using the Eclipse development model, plug-ins with the well known Eclipse workbench extension points and a widget toolkit with SWT API. Existing RCP applications can be run as Web applications with only minor changes. SWT, JFace and Workbench API RAP is very similar to Eclipse RCP, but it has an alternative implementation of the SWT API (called RWT) which renders the widgets remotely in a web browser. The RAP application runs on a servlet container and clients can access the application with standard web browsers. "

"Cappuccino is an open source framework that makes it easy to build desktop-caliber applications that run in a web browser. "

"Open Source projects built on Adobe technology Welcome to our online community site, built using our own products and targeted to support developers building open source projects for our products and platform. Now you can integrate existing or new open source projects in a centralized repository with simple functions and options. This site provides a consolidated hosting environment that transcends tools, geographies and functional teams and enables more efficient use of your time and resources. As the world becomes a truly collaborative development environment with open borders between heterogeneous tools and platforms, the use of tools like this needs to remain free of charge. So that's what we have done. Developers can freely create accounts and define new projects. Projects created here must be and will be open source, and will not be owned by Adobe. The exact open source license used for each project is up to the project lead, and must be clearly stated in the project description. "

"Essentially, a widget is a local HTML/CSS/JavaScript web application. A mobile phone user downloads a widget once, and from that moment on he has a web application stored locally on his mobile phone. Although currently widgets are mostly used for relatively limited functions such as clocks, RSS readers, or Twitter or Flickr clients, as well as for games, there's no theoretical reason why they couldn't contain a complete, complicated, JavaScript-heavy web application; for instance a mobile-optimised spreadsheet application."

"Google Web Toolkit (GWT) is a development toolkit for building and optimizing complex browser-based applications. GWT is used by many products at Google, including Google Wave and Google AdWords. It's open source, completely free, and used by thousands of developers around the world. "

""Coming from desktop application development, I have found the IT Mill Toolkit [Vaadin] to be a lot of help in the transition to web application development. With the toolkit, writing AJAX enabled web applications is as easy as writing Swing based GUI code. It hides so many frustrating details, and handles browser independence so I don't have to worry about it. Using the toolkit makes it quite easy for me to write sophisticated web applications."

"Enhance User Experiences with JavaFX 1.3 software The JavaFX 1.3 SDK is available today, delivering significant performance improvements, more UI controls, and a range of valuable new functionality."

"Build engaging, cross-platform rich Internet applications Flex is a highly productive, free, open source framework for building expressive web applications that deploy consistently on all major browsers, desktops, and operating systems by leveraging the Adobe® Flash® Player and Adobe AIR® runtimes. While Flex applications can be built using only the free Flex SDK, Adobe Flash Builder™ (formerly Adobe Flex® Builder™) software can accelerate development through features like intelligent coding, interactive step-through debugging, and visual design of the user interface layout."

"Welcome to the new Flex.org! As you can see, we've give it quite the facelift. You'll find a brand new showcase of Flex applications in the "What's Possible" section. You'll also find an extensive list of resources that has been updated for Flex 4. Additional content will be added over the next few weeks so check back often. "

OpenLaszlo is an open source platform for creating zero-install web applications with the user interface capabilities of desktop client software.

"Apache Tapestry is an open-source framework for creating dynamic, robust, highly scalable web applications in Java. Tapestry complements and builds upon the standard Java Servlet API, and so it works in any servlet container or application server. Tapestry divides a web application into a set of pages, each constructed from components. This provides a consistent structure, allowing the Tapestry framework to assume responsibility for key concerns such as URL construction and dispatch, persistent state storage on the client or on the server, user input validation, localization/internationalization, and exception reporting. Developing Tapestry applications involves creating HTML templates using plain HTML, and combining the templates with small amounts of Java code. In Tapestry, you create your application in terms of objects, and the methods and properties of those objects -- and specifically not in terms of URLs and query parameters. Tapestry brings true object oriented development to Java web applications. "

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Developed four years ago by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly. Django focuses on automating as much as possible and adhering to the DRY principle. Dive in by reading the overview → When you're ready to code, read the installation guide and tutorial.

Prototype is a JavaScript Framework that aims to ease development of dynamic web applications. Featuring a unique, easy-to-use toolkit for class-driven development and the nicest Ajax library around, Prototype is quickly becoming the codebase of choice for web application developers everywhere.

According to Yahoo!'s Exceptional Performance Team, 40% to 60% of Yahoo!'s users have an empty cache experience and about 20% of all page views are done with an empty cache (see this article by Tenni Theurer on the YUIBlog for more information on browser cache usage). This fact outlines the importance of keeping web pages as lightweight as possible. Improving the engineering design of a page or a web application usually yields the biggest savings and that should always be a primary strategy. With the right design in place, there are many secondary strategies for improving performance such as minification of the code, HTTP compression, using CSS sprites, etc. In terms of code minification, the most widely used tools to minify JavaScript code are Douglas Crockford's JSMIN, the Dojo compressor and Dean Edwards' Packer. Each of these tools, however, has drawbacks. JSMIN, for example, does not yield optimal savings (due to its simple algorithm, it must leave many line feed characters in the code in order not to introduce any new bugs). The goal of JavaScript and CSS minification is always to preserve the operational qualities of the code while reducing its overall byte footprint (both in raw terms and after gzipping, as most JavaScript and CSS served from production web servers is gzipped as part of the HTTP protocol). The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin (becoming 10% after HTTP compression). Starting with version 2.0, the YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter's regular-expression-based CSS minifier.
