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.
JCatapult is a development platform written in Java. Built for modularization, JCatapult allows developers to build modules such as a blog, content-management system, wiki, or any other reusable set of features and use them across multiple applications. Built on top of open source technologies, JCatapult is a robust and scalable platform. However, it is also agile and lightweight because it uses a convention over configuration approach.
Location Source is an implementation of Java's Location API (JSR-179). It is intended to give Java applications access to location data on platforms that do not have a JSR-179 implementation of their own. It currently only runs on Windows Mobile using IBM's WebSphere Everyplace Micro Edition (WEME) 6.1.1 bu can easily be extended to run on other platforms. For example, you could use it on any laptop by tying it into SkyHook's Loci API.
The OpenUDDI project is focused on creating a high performance, easy to use UDDI v3 compliant server and client library. The server and client is built using Java, version 5 for the server and version 1.4 for the client. The server uses Hibernate, and supports a wide variety of SQL databases for data storage.
The Spiffy Framework is a collection of well-tested and often used helper methods and utility classes. Such methods and classes solve existing and recurring practical problems, and remedy annoying features of the Java language or its frameworks. The value of this framework is not only the code, but also the ideas for solutions to the problems. The goals are to collect and centralize "utility abstractions", and to serve as a repository of knowledge/smart ideas for programmers to learn.
Amiba is a Gene Expression Programming (GEP) framework for Java. GEP is, like genetic algorithms, a branch of evolutionary computing. The framework separates the process of evolution from the process of interpretation of the chromosome, allowing the use of various schemes. For example, graphs may be used as terminals and graph operations as operators in the chromosome instead of the usual double precision numbers. It implements mutation, transposition, and recombination. Options and rates are easily configured through an XML file. A mechanism to load fitness cases in bulk is also provided.
