e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set.
Webplay creates, from a collection of MP3s and Ogg Vorbis files (indexed from a directory or MySQL/PostgreSQL database), a Web-based jukebox with support for multiple independent streams. If Lame/oggenc are available, it can change the bitrate or codec of a file in real time to a selectable value. Each user controls their stream via a Web interface and can skip back, forward, or to a specific track; increment or decrement the bitrate; and check the current playlist, song, or bitrate. Playlists can be looped, randomized, played locally on the webserver, edited, deleted, reused, or renamed.
LiteWebServer (LWS) is a small, modular Web server and Java web container. It is based on code from Apache's popular Tomcat server, tweaked and extended for easier installation and management. It consists of a set of modules that can be installed separately, so you can install and manage exactly the features you need. The base module provides basic Web server features (HTTP/1.1 support) and support for the Servlet API. Add-on modules provide additional features, such as JSP support. Installing new modules and upgrading or removing existing modules is as easy as can be with the bundled JustGetIt module manager.
The Lightweight Java Game Library is a native binding for OpenGL and OpenAL written with game developers in mind. It allows the full OpenGL and OpenAL APIs to be exposed without the penalties associated with competing methods, nor the limitations of APIs such as Java3D. Tutorials and demos are available, and Windows, Linux, and Mac OS X are supported.
The Platonos Projects are a group of sub projects aimed to provide Java developers with a stand-alone plugin engine as well as a pluggable Swing application framework similar to other RCP (Rich Client Platforms) available. The goal is to have an out-of-the-box runnable Swing application with the more common pieces applications contain, such as preferences, help, file I/O choosers, configuration, and more all via plugins which can be left out if not needed. Building upon the shell is very easy by simply adding plugins that provide extended behavior for existing plugins, or adding new plugins that will then be extended by other plugins.
Caudex is a distributed document/reference management system. Its features include support for BibTeX reference types, reference organization in hierarchical categories, BibTeX export, multiple attachments (eg PDF files) for each reference and a servlet-based Web interface with full-text search on the PDF attachments. It is optimized for offline work, and local reference collections can be synced with servers at any time. Multiple local storages are supported and can optionally be synced against different servers.
MiGLayout is a versatile and flexible Swing and SWT layout manager. It uses string constraints or API type-checked constraints to format the layout. Strings are both short to type and easy to understand. MiGLayout can produce flowing, grid-based, absolute (with links), grouped, and docking layouts. It was created to be to manually coded layouts what Matisse/GroupLayout is to IDE-supported visual layouts.
