As rwzeitgeist says, there's no version of ITOS which ships with Java support.

The web browser in OS2008 is a Gecko-based browser, similar to Firefox 3; so fully supports JavaScript. However, apart from a similarity of syntax there is no commonality between JavaScript and Java.

Jalimo can be used to run Java SE applications, using SWT as a GUI toolkit and this is making good progress. Even without using the Jazelle extensions supported by the CPU, apart from start-up time, it's not as slow as I was expecting in use.

There are no browser plugins which hook into Jalimo or similar to provide Java applet support in the browser, as far as I'm aware.
