Free only java software for linux

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).

JSON-RPC-Java provides an RPC implementation that allows JavaScript DHTML Web applications to call remote methods in a Java Application Server (AJAX functionality) without the need for page reloading.
JSON-RPC-Java library is an enabler for the next generation of fast and highly dynamic enterprise Java Web applications. Minimal changes (if any) are necessary to existing server-side Java code to allow calling from JavaScript (such as the marshalling and unmarshalling of special types), as JSON-RPC-Java dynamically maps JavaScript objects to and from Java objects using Java reflection.
Enhancements:
- The license has changed from the LGPL to the Apache License, Version 2.0.
- New object registration, lookup, and unregister APIs have been added to JSONRPCBridge.

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:

The simplest way to compile this package is:

1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.

Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.

2. Type `make to compile the package.

3. Optionally, type `make check to run any self-tests that come with the package.

4. Type `make install to install the programs and any data files and documentation.

5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean. There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.

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. The controller has two modes for request processing: synchronous and asynchronous. Validators (commons-validator) are also supported.
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.

SCAP-Java is an automatic thematical mapping software. It draws colors or symbol maps from your data, with step by step procedures coherent with the cartography semiology methodology.

SCAP-Java was developed for education and map production, with an emphasis on usability: its easy to create a PDF map from spreadsheet data and geospatial datasets (mif/mid).

Java::SJ is a highly configurable Java program startup system.

SYNOPSIS

sj myprogram.sj

This module allows you to very easily run Java services that rely on complex configuration at the VM and library level. It also provides an easy way of specifying a sensible default configuration that can be overridden by specific applications should they need to.

The system is configured on a machine and application level. The system looks for configuration files in a set of well-known locations, currently these are:

/etc/sj.conf
.sj.conf in users HOME directory
.sj.conf in current working directory

Every application is defined in terms of a similar configuration file. The configuration system has been designed so that it is easy to write a simple and minimal configuration file for a program.
Provided the system has a fairly complete configuration associated with it then an application configuration file need only have the class name to be executed.
