iLiad Get your Java VM for iLiad here

[scotty1024]

OK OK I know, I was supposed to be working on my iDS server... but instead I just couldn't help testing out my spiffy new compiler chain for the iLiad itself.

I talked about a calculator for X but you know, that's just so boring.

So instead, I compiled wonka for the iLiad. And I got wonka working.

So, wherever that wiki is, I think I claim legitimate rights to "first person to compile Java VM for iLiad" and "first person to run a java application on the iLiad".

I've compiled wonka with X11 support, so, here's your new tool chain: java.

No messing around with cross compilers, just compile your code using your favorite Java 1.4.X (or lower, no java 1.5, sorry...) test it on your native system and when it's working: send it to your iLiad and use wonka to run it.

Yeah I know, still need to work on the X11 trigger stuff. But now we can worry that into Wonka and all the java code gets it for free.

Unpack the tar ball onto your favorite memory device. Put you class files in fsroot/system, cd to your memory card and then invoke ./wonka <your class name>

I'm off to tweak my Java RSS feeder to suck da' goods into my newspaper directory directly from my iLiad. Expect another posting shortly.

And of course what fun is it to have a Java VM, vi (via busybox) and not be able to compile java source on your iLiad?

I unpack that zip at the same level as wonka. An example of using it to compile my (working) RSS feed puller:

./jikes -g -classpath ../fsroot/system/wre.jar:xpp3-1.1.3.4.K.jar TheDailyiLiadian.java

So with a few more tweaks to wonka for the e-ink, there you have it: a complete SDK on the iLiad itself.

congratulations, scotty.

nice work. I'll try it next weekend, this one is too busy, unfortunately.

Great work Scotty!
Will give feedback once I've given it a go.

[CommanderROR]

Good work once again Scotty1024!!!

Please feel free to post your achievements in the "Iliad apps" sticky at the beginning of your forum for everybody to find.

I wonder what will happen once the "real" SDK arrives...:-)

I hope the question to ask is only, which time, not if they ever will release it.

Yes, looks interesting, though I'm probably not going to get any time to look at it until the weekend after next...

Well, we will get Look and Feel. And this is important. Plus smooth updating.

Currently the update of the screen can be done, I believe, via an
exec /usr/bin/displayMgrClient
or whatever way java has to execute external programs.

Usage: displayMgrClient -<option> <argument>
no arguments : send messages to local loop
-d <dotted decimal ip address> : send messages to ip address
-h : display this message
-p : test of partial update
-r <seconds> : repeat a full update every <seconds>
-t : update toolbar area

Also at your risk, you could kill the Xserver and restart it without the -p flag, because that flag is suppossed to "disable the partial update". But surely iRex has good reasons (buggy, most probably) to keep it disabled.

Good you tell to use a memory device, and not the rootfs!


Can you take some pictures, design256's style, of the running thing?

Sounds like I need to reverse the protocol being used and put that into Wonka's X support, then it will have "smooth updates" too.

Thanks for the tip.

Hey scotty, terrific job and as soon as I'll get my iliad (cause now I'll definitely get one) I'll give it a try, since I have a little java prog that's just begging for the capabilities of the iliad.

I have though two questions:
1- does this still work after the hole-plugging of 2.7.1?
2- As you said wonka doesn't support 1.5 java features. So have you tried SableVM as an alternative? I read on their website that there already is an ARM port for it. Maybe it'll work?

Keep up the good work, you're my hero at the moment.

Edit: Uhhhmm, scotty? Any chance of getting an answer?

Of course, now that Java is open-source (GPL) it is just to compile it, I guess? No?

Or perhaps GCJ -- native speed and less memory usage... then I can start creating iLiad apps as well

So many postings... missed this one some how.

I've been poking Wonka around some more but wouldn't mind finding another ARM capable JVM. I haven't looked at Sable.

Right now I'm effectively derailed full time into figuring out the bluez stack. The bigger the applications get, the more they want a keyboard. Plus I'd like to be able to hit the Internet from the bus.
