JNode is the open-source project for making a Java Platform OS(Operating System). This project had take a exclusive track of making all the software in Java in itself. As Java Virtual Machine(JVM) only accepts bytecode so the Compiler used to develop native binaries out. In this way, nearly the entire system is able of being written in the JAVA programming Language.

Ewout Prangsma firstly started work of developing the Java Bootable System(JBS) during 1995 .He had caught special feature of Java. In his mind he himself imagined a system that was not only a VM, but a complete runtime environment that does not need any other form of operating system. So is had to be a light weight and most important flexible system. The author was not satisfied with the C and assembly language required and head towards on to a new attempt called JBS2.

Jnode uses only two languages i.e. Java and Assembly Language. This system presently understands the FAT,NTFS,ext2 and ISO 9660 file system. It also has a GUI(Graphical User Interface) with USB peripherals and TCP/IP network protocol. It can be boot from CD or run in any popular emulator. It uses GNU Classpath Java Library and can run any Java Programs.

The latest version of JNode can be found in :
