The Arakhnê.org Foundation Classes (AFC) is a collection of Java libraries (based on Maven) that provides a collection of utilities that are not provided in the standard Java API. Many utility classes are provided: file filters, progress indicators, arrays, collections, VM utilities, text utilities, math tools (point, vector, matrix, shape, etc.), widgets for AWT, Swing, and Android, a platform-independent graphical API, and more.
Web4thejob is a Java framework for rapid development of data-centric Web applications. It is ideal for those who seek a component-based event-driven full-stack Web development framework capable of producing elegant desktop-style Web applications which can automate any business domain. The framework addresses the automation needs of business domains by introducing "joblets". A joblet is the equivalent of an app on a mobile platform. Similarly to mobile apps which can turn a cellular phone to a social meeting point, a game console, or TV set (i.e., the smartphone), joblets can turn Web4thejob into a Web application suitable for any business domain.
CubicWeb is a semantic Web application framework that empowers developers to build Web applications by reusing components (called cubes) and following the well known object-oriented design principles. Its main features are: an engine driven by the explicit data model of the application; a query language, RQL, similar to W3C’s SPARQL; a selection+view mechanism for semi-automatic XHTML/XML/JSON/text generation; a library of reusable components (data model and views) that fulfill common needs; the power and flexibility of the Python programming language; and the reliability of SQL databases, LDAP directories, Subversion, and Mercurial for storage backends.
hyphenType is a commandline interface for Java. It turns raw arguments into Java objects, organizes return codes to the operating system, stops exceptions from going to the console, has beautiful --help, supports internationalization, handles input channels, and offers advanced unit testing. Additionally, hyphenType provides a tool to dynamically edit Java annotations and to load annotation properties from property files.
CT-gui is a touch-friendly GUI toolkit which can be used on the Linux desktop and on Android devices. Development can be done quickly and easily on a Linux box, then ported to an Android tablet or phone. For graphics, only OpenGL or OpenGL ES is used. For audio, ALSA is used for Linux and OpenSL ES for Android. As you might expect, the Android SDK and NDK should be installed on your system. Two demo projects called CT-synth and CT-farfisa are included, which are a polyphonic synthesizer with about 20 built-in patches, and an organ with many sounds. These can be played using the mouse or your fingers, or with an attached MIDI keyboard.
C5Connector.Java is a backend for the Core Five file manager. It provides a bridge between the file manager and a storage backend and works like a transparent virtual file system or a proxy. It includes a default implementation for accessing the local filesystem (on the server side). The API encapsulates the building of JSON and is intended to be used within JSPs as well as with a template engine like Velocity or FreeMarker.
