Is there any way to write an operating system in Java? I know it's possible to use C, but I prefer Java. It's easier to use.

A small portion of the OS would need to be written in assembly, beyond that it's theoretically possible to use Java, though I'm not sure if it's been attempted.

You would probably wind up using JNI(think that's the right now), and a lot of other third party api's and such...Just my guess though.

just remember that you'd probably have to code your own jvm into the OS somehow

Dogtree- Yeah, I know that, same as with C.
server_crash- Yeah, I know that, same as with C.
Phaelax- Yeah, I know that, same as with C.
Actually, I was looking at Kaffe. Does anyone know of a JVM written in C or assembly that doesn't require things such as stdio.h? (which I apparently can't write, BTW)

Found one- I'm just going to modify jNode.

Why... of course that isn't a JNode code snippet.. what a coincidence that the same exact code shows up in jNode and my OS!


PS: I need a name for it now.

If you have hardware with a JVM built into it (which is possible) you can indeed write the rest in Java.

Name it after me.


PS: I wrote Windows XP in java(not many know this), so if you need any help you can contact me.

Hi everyone,

Is this really true?? Did you also write the kernel in java??
What about the networking part(talking to the modems using java)??

What about disk partining and formatting - were these codes also written in java??

Can your OS support most of the hardware on the market??


If you have really created something like that i think you should open-source it so people could further develop it as i think that such an OS could be very beneficial to the computer world.

It would really be great to hear a reply from you on this topic

Thank You

Yours Sincerely

Richard West

server_crash: No, that would imply that it crashes when used as a server. But I might need a little help. It will be open source, probably under the GPL.
