- Echo 2 – Echo2 is the next-generation of the Echo Web Framework, a platform for developing web-based applications that approach the capabilities of rich clients. The 2.0 version holds true to the core concepts of Echo while providing dramatic performance, capability, and user-experience enhancements made possible by its new Ajax-based rendering engine.
- ActiveMQ Ajax Support – Ajax support in ActiveMQ builds on top of the REST connector for ActiveMQ which allows any web capable device to send or receive messages over JMS. All the Ajax examples are currently using OpenRico.
- Tacos – The Tacos library project provides components and ajax behaviour for the Tapestry java web application framework. Most of the library relies almost exclusively on Dojo.
- WebWork 2.2
Awesome AJAX support built on top of DWR and Dojo. Form validation, tabbed panels, remotable forms, and remote divs. More AJAX components will be coming in subsequent releases.
- Simple Web Framework – The Simple Web Framework (SWF) is an event based framework targeting Struts developers who want to build rich Web applications but do not want to migrate to JSF. The SWF is built upon the same Jakarta commons basis as Struts, but uses a different request processor (front controller.) The SWF event model supports XmlHttpRequest (as well as form/submit) based event posting, similar to VB.NET or JSF, with In place Page Updating (IPU) rather than page reloading.
- Wicket 1.1 rc2 – Dojo, Scriptaculous and Wicket integration. The release consists of an Ajax handler, allowing you to create your own custom Wicket Ajax components based on the Dojo toolkit.
- Zimbra – Zimbra is an open source server and client technology for AJAX based messaging and collaboration. The collaboration server is built using Java based technologies. The server features file based message storate, a SQL metadata storage, Lucene based search, clustering, replication, archiving and LDAP support.
- Orbeon Forms – An XForms engine much improved over OPS 2.8′s, significant improvements in the Page Flow Controller, and more. The XForms engine is based on Ajax technologies. This makes the XForms engine much more responsive to user interaction than with OPS 2.8.
- ZK – ZK is an event-driven, XUL-based, AJAX-embedded, all Java framework to enable rich user interfaces for Web applications. With ZK, you represent and manipulate RIA in XUL/HTML components all at the server similar to how you developed desktop apps. ZK includes an AJAX-based event-driven engine to automate interactivity, and a rich set of XUL-based components.
- JSP Controls Tag Library – JSP Controls Tag Library (the “Library”) provides the lifecycle for portlet-like JSP components. The Library does not require a portal engine or other central controller. The components built with the Library can be used in any JSP-based application. The Library supports two request processing modes: Non-Ajax and Ajax. Pages composed with JSP Controls Tag Library look and behave the same way whether they run in Ajax mode or not.
- XAP – The basic intent of XAP is to leverage existing Ajax projects such as Apache Kabuki and Dojo, as well as other community efforts such as Eclipse openAjax. It aims to be pluggable with various Ajax toolkits, reduce the need of scripting and solve the development challenge as well as application maintenance challenges associated with Ajax programming.
- AJAX4JSF – Ajax4jsf fully leverages the benefits of the JavaServer Faces framework including lifecycle, validation, and conversion facilities, along with management of static and dynamic resources. Ajax4jsf enables page-wide AJAX support instead of the traditional component-wide support. This means you can define the event in the page that invokes an AJAX request and then the areas of the page that should be synchronized with the JSF Component Tree after the AJAX request changes the data on the server.
- ThinkCAP JX – ThinkCAP’s core is an advanced MVC framework that manages the runtime layout and presentation of GUI components, state management, data binding, validation, and data persistence. The framework is driven by Java classes and XML metadata generated by the Workbench. The current 6.0 version is very Struts-like.
- Helmi – Helmi’s Open Source RIA Platform permits client- and server-side engineers to work independently while communicating effectively through an object-oriented environment. This solution is composed of a 100% browser-based Client Framework, a Virtual Browser that enables cross-browser application operations, an Integrated Development Environment (IDE), and a J2EE-based AJAX Server Connect that simplifies transmitting data from server to client.
- Open jACOB – Open-jACOB is a Java rapid application development tool (RAD) based on Eclipse that enables the development of Rich Internet Applications (RIA) that are based entirely on Java. The primary goal of the jACOB Framework is to handle web applications with CRUD (create, retrieve, update, delete) with little or no Java programming. Instead of telling the application how to retrieve and how to display the data. The developer creates the Web-UI with a point&click eclipse UI-Designer.
- ThinWire – ThinWire is an open source development framework that allows you to easily build RIA applications. Notable features include a familiar event-driven GUI programming model, state maintenace via variables and not via session,
exclusively server-side language and supports all major browsers.
- ICEfaces –
ICEfaces is a RIA framework that delivers unique Ajax Push capabilities. Discover the power of Ajax Push and create collaborative and dynamic enterprise applications.
ICEfaces leverages the entire standards-based Java EE ecosystem of tools and execution environments. Rich enterprise application features are developed in pure Java, and in a pure thin-client model. ICEfaces is based on JavaServer Faces (JSF).
