I was on the look out for interesting and beautiful Web UI libraries for creating Rich Internet Applications, and I came across few options...
I need to explore it further and try out samples...
I would like to list the various options and give a brief idea based upon information collected online.
If readers have come across any of those technologies, they could gladly join in.
1. IT Mill Toolkit (Now Called as Vaadin)
2. LivePipe UI
5. Echo Web Framework
Echo is an open-source framework for developing rich web applications. From the developer's perspective, Echo behaves as a user interface toolkit--like Swing or Eclipse SWT. AJAX technology is employed to deliver a user experience to web clients that approaches that of desktop-based applications.
6. The Yahoo! User Interface Library (YUI)
7. WUI Web UI Framework
WUI (Web User Interface) is an MVC framework for writing web UIs in a single language: Java. Write web apps with components, widgets & events, not JSPs. Runs in any servlet 2.3 container. Similar to Model 2 / Struts, only better. Apache-style license.
8. Butterfly Web UI
Butterfly Web UI is a component oriented web framework for Java, like Wicket or Tapestry. The main advantage compared to these frameworks is that Butterfly Web UI integrates naturally with Butterfly DI Container, giving you a state-of-the-art dependency injection container to help you structure and decouple the internal components of your web applications.
Apart from the above, we also have GWT, JQuery and Extjs.
Information is wealth.. Kindly add information for better understanding of readers.
