Free compiling java to native code software for linux

Inline::Java lets you write Perl classes in Java and wrap/use existing Java classes. The project is an ILSM (Inline Language Support Module) for Java 2, and is part of the Inline family of modules.

Lightweight Java Game Library project is a native binding to OpenGL and OpenAL.
The Lightweight Java Game Library is a native binding for OpenGL and OpenAL written with game developers in mind.
It allows the full OpenGL and OpenAL APIs to be exposed without the penalties associated with competing methods, nor the limitations of APIs such as Java3D.
Tutorials and demos are available, and Windows, Linux, and Mac OS X are supported.
Main features:
- Speed
- Simplicity
- Ubiquity
- Smallness
- Security
- Robustness
- Minimalism
Enhancements:
- Dont allow switching to fullscreen when a custom display mode is in effect. This is a change from before, where the current mode was simply overwritten with the initial (desktop) mode

Java Tools is a lightweight integrated development environment for creating, compiling, and executing Java applications and applets.
Java Tools includes point and click access to the Java files, commands, and documents. It also includes a built-in text editor and user interface for the Java debugger.
It is intended for the new Java user who needs help getting started. Its also for the more experienced Java user who wants easy access to the Java commands and a text editor.
Main features:
- GUI with built-in help and small footprint.
- Point and click access to all files (Java, manifest, HTML, image and sound) and directories (package).
- Point and click access to all commands for compiling (javac), archiving (jar), documenting (javadoc), executing (java), debugging (jdb) and disassembling (javap).
- Point and click access to all documents (Java API Specification, Java Tools and Utilities, Java Features and Java Tutorial).
- Point and click creation of all files (Java, manifest and HTML) and directories (package).
- Point and click installation of distribution archive files (Java document, Java source code, Java Tutorial and Sun Tools).
- Automatic determination of class file dependencies for archiving (jar) and documenting (javadoc) Java files.
- Checking for unused, redundant and missing imports.
- Logging of all commands invoked by GUI.
- Code metrics for Java files.
- Built-in text editor (see Edit for details).
- Built-in user interface for the Java debugger with command-line editing and history.
- Self-installing executable (Java archive file).
- Comprehensive installation and user documentation for Java and Java Tools.

Java Units Generator and Converter (JUGC) is a Java tool and library for converting between measuring units.
It makes it possible to define units, their relationships and translations in files, to generate code from those definitions and deploy the generated code as a library in a Java project.
The generated code can then be used to convert values from one unit to another.
Enhancements:
- This initial version does the basic conversions using double precision floating point.

Java-GNOME is a set of Java bindings for GNOME and GTK libraries, so GNOME applications can be written in Java.

libgtk-java 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.
