OpenGL for Java, formerly known as GL4Java, supports Java with a native OpenGL mapping.
The OS native OpenGL functionality is avaiable from Java for many OS: Linux/GNU+XFree86, Unix/X11, MacOS, Win32.
Enhancements:
- removed the hack (which I put in sometime ago to get VooDoo3 working) that forced gl4java to choose a double buffered pixel format (the demos that used single buffer did not work) (thanks JYB)
- fixed the tessdemo and tesswind applets (thanks JYB).

Jeffs Java Scanf Library is an implementation of the C-Runtime scanf, fscanf, and sscanf functions.

The syntax of format strings is very similar (%*s, %3d, etc.) to that of the standard C implementation of scanf.

Instead of taking wrapper objects, all scanf functions return an Object[], whose types can be inferred from the format string.

Construct is a framework for command processing. It is based on a request/response cycle managed by a Controller. Construct-java has support for filters, filter chains and command chaining.

Main features:
- Synchronous/Asynchronous request procesing
- Command chaining (Chain of Responsability)
- Apply filters before and after request processing
- Commons-validator support
- Spring integration
Enhancements:
- Open source release to java.net.

The Java developer is ideal for beginners, based on J2SDK 1.3 version, thats why it can be runned on all the operation systems except Windows. Its editor shows the code with syntax highlight, it has redo-undo function.

The work is easy with the structure panel and the file browser. You only need one push-button to compile/run, shows the compiling errors clearly. Running is in an virtual console at the same time, so writing console programs can be possible.

Free Java software can also be used not just in Java but for acquiring HTML language. Multiple languages are supported, and an English translation is included.

Java-GNOME is a set of Java bindings for GNOME and GTK libraries, so GNOME applications can be written in Java. Java-GNOME is implemented as a JNI layer that delegates the Java calls out to the underlying C library.

Installation:

See the INSTALL file in each module for instruction on how to build the binding from source.
