Vaadin - JAVA Framework

Vaadin is a web application framework for Rich Internet Applications (RIA). In contrast to Javascript libraries and browser-plugin based solutions, it features a server-side architecture, which means that the largest part of the logic runs on the server. Ajax technology is used on the browser side to ensure a rich and interactive user experience. Developers compose the application user interface from components such as the Button, Table and Tree. The components use events, listeners and data binding to communicate with each other and with business logic. The component-based architecture together with the data binding features help building applications that are easily modularized and refactored as needed.

Pandora - JAVA Framework

Pandora is an easy to use, fast and lightweight framework for creating web applications with Java. Pandora uses Velocity for templating and provides support for Hibernate as persistence layer. It has great support for handling formular input with validators etc. and for lists, tables and trees (filtering, sorting, searching for free).

SerfJ - JAVA Framework

SerfJ is the easiest way of developing Java REST web applications. It helps you to develop your application over an elegant MVC arquitecture, giving more importance to convention than configuration, so for example, you will not have to have configuration files or annotations in order to specify which view serves a controller's method. However, SerfJ is very flexible, so if you want to jump over those conventions, you can configure the behaviour of your applications as you like.

fleXive - JAVA Framework

[fleXive] is a Java EE 5 open-source framework for the development of complex and evolving (web-)applications.

Hamlets (previously known as IBM Servlet-based Content Creation Framework)

Hamlets (previously known as IBM Servlet-based Content Creation Framework) is an open source system for generating dynamic web-pages originally developed by René Pawlitzek at IBM. A Hamlet is a servlet extension that reads XHTML template files containing presentation using SAX (the Simple API for XML) and dynamically adds content on the fly to those places in the template which are marked with special tags and IDs using a small set of callback functions. A template compiler can be used to accerate Hamlets. Hamlets provide an easy-to-use, easy-to-understand, lightweight, small-footprint, servlet-based content creation framework that facilitates the development of Web-based applications. The Hamlets framework not only supports but also enforces the complete separation of content and presentation.

RSF - JAVA Framework

RSF is an open source web programming framework, with roughly the scope of Sun's JSF. RSF is written in Java, and is built on the Spring framework. RSF features a pure-HTML templating engine named IKAT, which achieves the cleanest separation between presentation and logic yet made - build "components" using pure HTML and libraries of code rather than heavy framework base classes. RSF also features a lightweight request-scope Spring clone, RSAC, which brings the magic benefits of inversion of control into the request scope. RSF currently has integrations for Hibernate, JSR-168, Cocoon and Sakai.

Restlet - JAVA Framework

Restlet is a framework that brings the simplicity and efficiency of the REST architectural style to Java developers. It is composed of two parts, a neutral API and a reference implementation (Noelios Restlet Engine). It supports all REST concepts (resource, representation, data, connector, components, etc.) and is suitable for both client and server REST applications. The server connectors provided are HTTP (via Mortbay's Jetty or an adapter Servlet) and the client connectors are HTTP, JDBC, and SMTP (via JavaMail).

caramba - JAVA Framework

The caramba framework is built from bottom to top with one main goal: creating Responsive, Rich Internet Applications. With the AJAX technology we could already achieve this, but it was hard to debug, error prone and time intensive to make it work. We are sure that simplicity can be achieved by following the event driven architecture: Caramba is 100% event driven, so very, very easy to use. Using Caramba makes it possible to make fancy, responsive web-applications without having to write a single line of JavaScript. You don't need to learn another language. Just the good old java syntax and JSP, that's all you need to know to get started.

RIFE - JAVA Framework

RIFE offers an alternative approach to web application development and design. It builds upon the Java platform, but offers all required tools and APIs to implement and perform all common website related tasks in a fast, intuitive and consistent manner. RIFE has been designed for perfect separation of tasks during a development cycle. Every developer, dba and designer only has to focus on his own tasks. At any moment the work can be effortlessly integrated with the work of the rest of the team. This results in a loosely coupled and very robust system. One can make incremental improvements with little or no risk of unwanted side-effects elsewhere in the system. RIFE is composed out of a large collection of modular parts, which include:

 * web application engine,
 * integrated web continuations,
 * customizable multi-format template engine (html, xml, sql, java, txt, ...)
 * support for template content transforming through for example XSLT,
 * authentication framework,
 * database query builders,
 * simple persistance layer,
 * fault-tolerant JDBC wrappers and connection pooling,
 * web-oriented database utilities,
 * central data repository,
 * cron-like scheduler,
 * configuration framework. The central part is the engine which formalizes all aspects of dynamic web development. It graciously solves all doubt, confusion and maintenance problems of HTTP's statelessness and liberal CGI interface.

Barracuda - JAVA Framework

Barracuda is an open-source Presentation Framework designed to make it easier to build servlet based webapps by applying proven client-server patterns to the web development paradigm. It features a DOM based templating mechanism for better separation of code from content (default XMLC), a UI component model that provides a series of server side widgets (table, list, template, etc) that make it easy to manipulate DOM structures, and a strongly typed MVC interfaces just like in Swing. With support for multiple markup languages (HTML, WML, XML, etc). It has an event model that provides Model 2 style flow control and allows for true event driven programming on the server. You can add listeners to components and your server-side event handler code will automatically get notified when an action occurs on the client.

Macaw - JAVA Framework

Macaw is an object-publishing framework designed for local web applications. Freemarker is used for presentation, Jetty is used as the default web container, and there is a basic integration with Hibernate (but other persistence mechanisms can be used). The framework requires two layers over the top of "business logic" classes: a Java web layer where certain simple method and class naming conventions are used to facilitate easy mapping of data to and from HTML, and Freemarker page templates. A small number of Freemarker tags are defined to enable references to Macaw-based objects within the page templates.
