CloverETL is Java-based tool/framework for data integration and creation of data transformations. It is component based and follows the concept of transformation graphs which consist of individual nodes/components performing simple (or complex) operations on data. Any transformation can be defined as a set of interconnected nodes through which data flows. CloverETL can be used as a standalone application or be embedded into a larger project.
SmartPool is a connection pooling component that is modeled on connection pooling features provided by application servers. It makes an attempt to solve critical issues like connection leaks, connection blocking, and open JDBC objects (such as Statements and PreparedStatements). It features support for multiple pools, automatic closing of associated JDBC objects, detection of connection leaks based on configurable timeouts, connection usage tracking, and monitoring of the run-time status of pools.
YAJOGLB (Yet Another Java OpenGL Binding) allows Java programmers to access their native OpenGL library. The library is implemented using Java's JAWT to access the native windowing system, along with JNI calls to OpenGL. Programs using the binding must use the shared library provided, since this is not a pure Java library.
featherCache is a lightweight Java cache implementing a map interface and storing objects on disk. Multiple sections and expiration times are supported. It requires no third party components, has simple integration, and can also be used to store program settings represented by serializable objects. It was used for a long time as a part of the Sight Web agent generator.
The Deimos Project is a 3D space combat simulator and modular game library collection. It includes a 3D modeler designed with a programmer's needs in mind. It allows you to construct 3D models by writing Java source code. All you need to design a model is a computer, some graph paper, and a pencil. The modeler's internals function as a simple OpenGL scene graph API, without preventing the use of low-level OpenGL commands. For storing settings and other hierarchically-representable data, the project provides a Hierarchy library that stores data atomically using XML. It also features a timing library, a game object container system, and many other features.
