iLiad Java on the iLiad

[R2D2]

On the Zaurus (ARM with Linux OS) the Jeode Java runtime environment shows:

java version "J2ME Personal Profile for Zaurus 1.0"
J2ME Personal Profile 1.0 (build 1.0_fcs-b25)
J2ME CDC-HI 1.0_v01

which means more or less in practical terms:
Take a Java 1.1 applet or application and it will run.

I just see linux listed in there with an intel architechture and the iLiad has a 400MHz INTEL X-Scale Processor.

Sorry I am not really savy in those thigs yet.

The history of the ARM chip is a adventureous one. As you may know, it was the "Archimedes" family of chips, a british computer system. They evolved into a architecture suitable for portability and particularly for ebooks (I remember an announcement in this sense already in 1995-96). But Apple got controls of the company in the age of development of the Newton, and delayed its general use (it was claimed to be just a chip to be user in postscript printers).

After the Newton fall, the company went into a licenseeing politic. This is, they do not fry the chip, they just let other companies to made it. Intel got the rights to produce it, and created the line XScale for this production. I am not sure if it is property of Intel anymore, btw.

Yep more or less, it is. But iLiad should license Jeode, as you said.

We could try some of the free java engines, but it seems me a long range project for the first week (hey, I am still "In Transit"). Another interesting alternative could be to port Python.

IIRC the kaffe open source JVM can run on xscale linux (but was not complete last time I checked). You can get something called J9 from IBM for very little money (IIRC even for free while doing development if you download some workshop version from them).
And then there is JamVM: http://jamvm.sourceforge.net/
SableVM has been reportet to work on xscale, too: http://sablevm.org/
There is another VM at the 1.3 language level originally developed by acunia systems called wonka but their site seems to be down and I cannot remember who took over development.
Given enough time and a repaired Iliad I will eventually try these. I had briefly looked at superwaba a long time ago and of what I remember they had their own API which was not compatible with the usual JDK classes, it would be nice if anybody (cervezas?) could look into that and determine if sourcecode would still be reusable.

Please let us know about your progress. It would be really cool to have a working vm on the iLiad.
