- Reasonable Server Faces (RSF)
Here is the short summary of RSF features: Pure-HTML templating, with a lightning-fast renderer, IKAT Build "components" using libraries of HTML rather than libraries of code. Both clients and framework use Spring for IoC throughout, no need to learn another file format or semantics. VERY lightweight, minimal and fast. Handles complete request lifecycle, but a fine-grained modularity allows you to plug in your favorite flow architecture (e.g. Spring Web Flow), your favorite persistence layer (e.g. Hibernate, iBatis). Ultra-lightweight component tree allows zero server state processing of requests, without closing the door to "heavy" persistent-component application styles. Pure bean programming model (like JSF, NO interfaces or base classes appear in your data model) Abstract component tree isolates view producers from the rendering technology. Default rendering system produces completely valid XHTML, as "accessible" as the template files you provide, which while requiring no JavaScript to operate, is extremely friendly to JavaScript and AJAX-rich development. * "Right first time" rendering gets URLs, styling and layout correct even in complex portal/multiple client environments. Includes a request scope application context (RSAC) both for clean request-scope programming free of ThreadLocals, as well as for request model. Highly modular architecture allows "take-it-or-leave-it" integration with RSF - use just the renderer standalone (like a much smarter Velocity), use the renderer plus request decoder, or use the whole framework with your favorite components plugged in. RSF itself built using Spring and RSAC, so even core components can be replaced by just editing a config file. - Echo 2
Echo 2 allows you to code Ajax apps in pure Java (Demo)which automatically generates HTML and Javascript. - ItsNat, Natural AJAX
ItsNat is an innovative open source (dual licensed Affero GPLv3/commercial license for closed source) Java AJAX Component based Web Framework. It offers a natural approach to the modern Web 2.0 development.
ItsNat simulates a Universal W3C Java Browser in the server; the server mimics the behavior of a web browser, containing a W3C DOM Level 2 node tree and receiving W3C DOM Events using AJAX. Every DOM server change is automatically sent to the client and updated the client DOM accordingly. Consequences: pure (X)HTML templates and pure Java W3C DOM for the view logic. No JSP, no custom tags, no XML meta-programming, no expression languages, no black boxed components. The developer has the full control of the view.
ItsNat includes features like web-continuations (continue events), user defined events, timers, long running server tasks, COMET, DOM utils (to simplify DOM manipulation), resolution of ${} based variables in markup, ElementCSSInlineStyle support in the server, automatic page remote/view control of other users/sessions, XML generation, non-HTML namepaces support (like SVG in XHTML), JavaScript generation utilities, events fired by the server sent to the client simulating user actions for instance to test the view from the server, custom pretty URLs, previous/forward document navigation (pull and push referrers) with back/forward button support using AJAX, degraded modes (AJAX disabled and JavaScript disabled modes) etc.
ItsNat provides an, optional, event based (AJAX) Component System, inspired in Swing and reusing Swing as far as possible such as data and selection models, where every DOM element or element group can be easily a component. - SWATO
Swato is an opensource framework that help you develop your webapps easier via - DWR
DWR reduces development time and the likelihood of errors by providing commonly used functions and removing almost all of the repetitive code normally associated with highly interactive web sites - IBM
IBM's Rational Developer Tools include a standards-compliant extension to JavaServer Faces (JSF) for building and deploying rich AJAX applications. These is a mature library, which first shipped as a non-AJAX version in 2003, and has been enhanced to include AJAX in 2006.
