Welcome to jArt Java OS project!
Release 0.0.2 is available. Plase read current status notes.
Starting version 0.0.2 the kernel will be compiled under Cygwin environment (since there are some
problems using MinGW on Windows Vista).
What is jArt Java OS?
jArt OS is an operating system kernel, that is based on the kernel developed by
David Decotigny and
Thomas Petazzoni for the
SOS project. They have published a series of
articles in Linux Magazine France describing in details
the steps of building SOS.
The idea behind jArt is to integrate the Java Virtual Machine into the kernel, so the user code and
the part of the kernel itself can be implemented in Java. The jArt kernel is implemented in C
and currently uses interpretation of Java bytecode.
Current version of jArt contains basic SOS kernel functionality (memory management, user/kernel
multithreading). The jArt Virtual Machine (jArtVM) is running as a thread in kernel mode. jArtVM
performs interpretation of Java bytecode of classes integrated into the kernel (as a single
.jar archive). So, naturally, native code and Java code can run under jArt. All time-critical
functionality tends to be implemented in C (rather than in Java) to gain the system performance.
Following this link you will find the current development status
and changes history.

You may be interested only in the virtual machine (to run it for yout favourite operating system
but not as a part of jArtOS). In this case, please read this.
How to build
jArt is developed under MS Windows envorinment using MinGW
3.4.4 compiler. You can get this compiler along with a CodeBlock IDE.
Except the compiler, few more tools are required to build the jArt floppy disk image:
Please read `How to build' notes
for the detailed information on building the system and assembling the disk image.
