Catalyst is a Web application framework for Perl. It is based on Maypole, and adds many features from Ruby on Rails, Struts, Spring, and Tomcat. The development philosophy focuses on Don't Repeat Yourself, Lego-like components, Code Generation, and very strong testability. It supports a number of plugins, models, views, and controllers.
The Biochemical ALgorithms Library (BALL) is a framework for rapid application development in molecular modeling and structural bioinformatics. BALL provides an extensive set of data structures as well as classes for molecular mechanics, advanced solvation methods, comparison and analysis of protein structures, file import/export, NMR shift prediction, and visualization. Its extensibility results from an object-oriented and generic programming approach.
The Netty project is an effort to provide an asynchronous, event-driven network application framework and tools for rapid development of maintainable, high-performance, high-scalability protocol servers and clients. In other words, Netty is a NIO client server framework that enables quick and easy development of network applications such as protocol servers and clients. It simplifies and streamlines network programming such as TCP and UDP socket servers.
NUI is a GUI ToolKit intended to work with SGI's OpenGL API. It is similar in many ways to GTK+, Qt and even Win32, but with many enhancements in order to make it an easy and yet powerful tool for cross- platform GUI programming. It is currently developed on platforms supported by the NGL framework.
QicsTable is designed to provide a high performance and more functional alternative to the QTable object included in the Enterprise and GPL versions of Qt. It is built around an MVC architecture and implemented with the philosophy that common operations (setting fonts, alignment, etc.) should be directly supported and not require additional subclasses. It is offered under two licenses: the GPL for open source efforts, and commercial for companies requiring the ability to develop proprietary applications.
JasperServer is specifically designed to provide a general platform for business intelligence. Continuing the philosophy of JasperReports, JasperServer is aimed at providing a managed, stand alone Web reporting and analytic (OLAP) environment, capable of being embedded in existing Java Web applications. It also provides services to a variety of technologies through Web services, including the LAMP stack. By focusing on a clean business API and using an advanced inversion of control architecture, JasperServer can be easily integrated and customized for your needs.
