The DataBean package is a Java library that provides features for mapping a database table to a Java class (databean). The coding of the databean class must conform to a preset pattern so that the instances of the databean classes can perform common database operations without using much of the ugly SQL. DataBean is functional, stable, light-weight, and easy to use. It can make your application much easier to write when dealing with relatively unsophisticated database operations.
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.
JCons provides a library that bring color to your Java console. The Java console gives no methods to change the foreground or background color. With help of this library, one can make error messages red and success messages green, for example. Most Unix terminals can deal with ESC sequences, so they are used to make the Java console colorful.
StelsCSV is a JDBC driver that allows performing SQL statements and other JDBC operations upon text files (comma separated, tab-separated, fixed length, etc.). Using this driver, users can easily create a simple database consisting of plain text files. The driver can be used for writing data importing programs and migration tools. It supports most keywords of ANSI SQL92, table joins, INSERT, UPDATE, and DELETE statements, data types, aggregate, converting, string, and user-defined SQL functions.
HBCI4Java is a Java library for the HBCI home banking interface. It supports almost all aspect of the HBCI versions 2.01, 2.1, 2.2, HBCI+ and FinTS-3.0 (with PIN/TAN support). Its API is very application-oriented, so no knowledge about HBCI is required. The HBCI client package can be used to develop applications using HBCI features. The HBCI server package can be used to develop your own HBCI servers. This may be useful for credit institutes or software developers who want to setup their own HBCI test server.
BlueJ is an interactive Java development environment. It provides a unique user interface that presents a graphical display of the application classes and their relationships, and it lets users interactively create objects of any class. Once objects have been created, users can interact with them directly. This interaction mechanism allows for much greater testing and experimentation than in conventional environments. BlueJ is suited for teaching and learning OO and Java.
Lucane is a free groupware platform written in Java, designed with extensibility in mind. Some applications are bundled with the platform, like a peer to peer quick message service, client/server and peer to peer file sharing, shared drawing, multi-user chat, audioconf, forums, a shared calendar, and more. The platform as a whole provides easy development for your networked applications with an object based network protocol, client/server and peer to peer integration, user and groups management, internationalization, and more.
