Jainja JVM running a LWUIT GUI on HelenOS

Jainja JVM on the Chrome Web Store

It was pretty easy to write a new graphical backend for Jainja using the Pepper Plugin API. So it's possible to write Java graphical user interfaces on NaCl now !

A demo is available on the Chrome Web Store.

This port was not too hard thanks to the POSIX compatibility layer of HelenOS. The lack of some math libraries was filled by fdlibm. A package for HelenOS is available here

Jainja 0.8 released

Jainja is a JVM (Java Virtual Machine) written in Java. Focus is set on portability, not on performance. Jainja supports Java 1.5 features.

This release adds support for Minix, Haiku and Dart.

So Jainja currently works on Linux, Windows, xBSD, Minix, Haiku, Java SE, Android, GWT, and Dart

Jainja JVM on top of the Dart VM

I'm currently working on a new "platform" target for Jainja: Dart

I got some preliminary results but only simple applications are working at this stage.

Jainja VM

Jainja VM is a new JVM written in Java.

The VM can run on top of multiple environments : Java SE, Java ME, Android, Javascript, and even natively in a near future.

You can see Jainja in action in your browser (no Java plugin required, only a HTML5 browser): demo

Sources will be released during FOSDEM 2012.
