Java Web Parts
The AjaxTags component of the Java Web Parts project is a taglib that allows for very easy, purely declarative AJAX functions to be attached to any element on a page.
It is nice because it does not require you to change anything about your existing page, you can add AJAX features after the fact very easily. The taglib consists of two common tags, and two others that are less frequently used, which have one or two attributes apiece. Very simple! All you do is drop a tag directly after the element on the page you wish to AJAX-enable, configure an entry in an XML config file describing the AJAX event, and you're done!
AjaxTags comes with a number of request and response "handlers" which provide common AJAX functions (e.g. construct XML from a form and submit it, update a div with the servers' response, execute returned populate a select, transform returned XML via XSLT, etc). It also has tremendous flexibility for you to create your own handlers to do other things, like transfrom the server's response via XSLT using Sarissa (this was a contributed custom handler which is now standard in AjaxTags).
AjaxTags does not provide pre-made AJAX widgets as other libraries do, but it does provide the foundation to very easily and quickly build these (see the cookbook example of building Google Suggests with AjaxTags). AjaxTags also provides timed AJAX events, so you can continually refresh an iFrame for instance. AjaxTags is, in short, an exceedingly simple, powerful and flexible way to introduce AJAX into your applications without having to write ANY code yourself!
Ajax reusable GUI Classes and “loosely coupled” component based Framework
Raju’s GUI-API Ajax reusable GUI Classes are based on “patent pending” inventions, which let developers build easy to use and more flexible reusable GUI Classes than possible for traditional GUI Platforms such as Java/Swing or Windows/VC++.
- Developer's Guide Free for trial
- Technology summary
- Very Basic Tutorial for Developing a GUI Widget for GIS for a Newbie
- Tutorial for the technologies
- Proof for the inventions
To build superior online GUI applications than possible on the traditional GUI platforms, one needs superior GUI-API. Raju’s GUI framework offers simple and complete solution to build superior online applications. Raju's GUI-API will contain very lightweight and highly scalable GUI Classes. For example, fine-grained java-classes can be quickly composed to build GUI classes for larger components.
Although, component based processes are controversial, pioneer-soft strongly believes it invented a viable component oriented programming. The following web pages briefly summarizes the process:
- “Service access” to the interchangeable-parts for easy maintenance of the components/application
The basic proof is not complex: If the product-makers (e.g. computers and cars) were also cannot build interchangeable components and literally assemble them to create ‘hierarchies of loosely-coupled components’, they would also face crisis, similar to the software makers. These technologies are still needs to be peer-reviewed and accepted by other researchers, so the technologies not yet commercial.
Apache Struts 2
Based on a donation from the Oracle company to the Apache foundation, this is a graphical framework based on JSF model. You will have access to over a 100 components and other feature like validators, partial page rendering, skining and more.
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, Ajax-enabled components written with plain Java and HTML.

Cross-Browser Core Engine
Comprehensive Widget Library : 250+ widgets & functions
Cross Browser Ajax Debugger
The Backbase Ajax Debugger allows interactive, real-time debugging of the complete Ajax user interface. The developer loads the debugger inside the browser, on top of the interface being debugged. Once loaded, the debugger gives the developer a 360-degree view of the interface. For each element currently used in the Ajax interface, the developer can easily inspect the XML data, the DOM node, the computed style, the behaviors and also the variables. The tool is fully integrated with the tracer and command execution. Following the trace, the developer can identify UI elements that have caused execution errors, and fix those. The debugger works in all major Browsers (including IE). See: Demo of Debugger
Visual Ajax Builder (Eclipse Based)
Backbase offers a unique WYSIWYG visual Ajax development environment, specifically designed for Rapid Application Development of Ajax based applications. The builder is an Eclipse plug-in, is intended for professional and enterprise developers, and includes all the development tools and features necessary to cover the full Ajax based RIA application development lifecycle – from development to deployment. See: Demo Visual Ajax Builder
Java Server-side Integration Framework : JSP, Struts, Spring, JSF, JSR 168, WSRP
Backbase JSP / Struts / Spring Connector: add Ajax features to existing JSP, Struts, spring and HTML code, while making only minimal changes to your existing code base ("ajaxify" your existing java applications).
Backbase Portal Connector: enables you to create JSR-168 compliant portlets that do not require your portal page to re-render all portlets after each operation and also offers over 250 Ajax widgets and functions that simplify the development of your “ajaxified” portlets. The concept of the Portal Connector is that we want to avoid as many page refreshes as possible when interacting with a portlet. We’re using the WSRP protocol and JSR-168. To avoid page refreshes, we avoid rerunning the portlet class, because that would cause the entire portal page to refresh. So the main thing we do in an Ajax portlet is to dispatch to a view. When you need other functionality such as editing portlet preferences, you can define other JSR168 defined methods (like processAction) to take care of this.
Backbase JSF Edition: is a JavaServer Faces (JSF) implementation that takes advantage of the client runtime and Eclipse-based development tools. The Backbase JSF runtime performs the Ajax component rendering in the JSF presentation framework. It extends the JSF request lifecycle to work in a Single Page Interface environment, it synchronizes client-server state and facilitates data binding. Backbase Ajax JSF Components are pre-built and accelerate application development. Over 50 customizable UI components are included, and developers can also create their own components. Besides the ajaxified flavours of the standard JSF components, the JSF Edition delivers rich Ajax JSF components that combine rich client side and server side behavior such as the listGrid.

Software AG’s Crossvision Application Designer
An open source AJAX framework to create database applications for the WEB.
The target of this framework is to give the user the possibility to create a lot of formulars in a kind of a simulated MDI-interface. The user can switch between the web-formulars which were opened by himself using the window menu. With this the user can navigate through a large of data very easy because it is possible for him to keep the formulars open he is interested in. The framework supports tables with vertical and horizontal scrollbars and the user can change the width of the columns. Two look and feels exists currently. It is also possible to create your own look and feel. Unfortunately the tutorial is in german language but the documentation of the API is in english language.
An open source business-applications oriented Ajax framework with support for JPA/EJB3
We provided also an implementation thinked to be binded via interfaces to the application model.
As an optional package, it is included our implementation of the application model, complete of a data validation architecture (with an interface to "Hibernate Validator"), complex model such as tables, trees, view on tables, etc... If used with a JPA provider such as Hibernate it includes lookup validator, direct loading and storing from/to the data model, optimistic lock handling, etc...
Many other functionalities are provided for the programmer, but, by the way, the real think that makes the solution appetible is the final result in terms of usability.
