Ernest:
Greetings and best regards.
I've been working with Compaq's iPAQ 3650 PocketPC (WinCE 3.0)
handheld. I've got this delusion that I might be able to run some
form of JESS on this cool little device (ya know, portable expert
systems or qual simulations of some sort).... This gadget cranks
pretty fast (a 206 MHz RISC chip) with 32 Mb of RAM storage (seems to
be about 20 Mb still available for applications with all the stuff
I've already got on it, including the VM)!
Anyway, Sun has released a Personal Java Runtime (pjava) for CE for
the StrongARM that seems to run on the iPAQ just fine. Currently,
their release is up to the 1.13 spec (although they seem to have the
specifications set for an upcoming 1.2 CE VM). I seem to recall
among my older 'personal' JESS archives some functional code that was
compiled with an older Win 1.13 javac. I'm going through the CE VM
specs, and it seems like most of the core 1.1x classes are there,
including a major subset of AWT.
Laying this out, can you think of any serious "gotcha's" that might
crop up with using JESS 4.N (or even 5.N) source for this effort???
The Javasoft site has some notes about executing pjava through file
names embedded in html pages, and this seems pretty comparable to
embedding in a normal PC browser page. Offhand, I would guess to
start that the console.Applet at least needs tweaking for screen
dimension limits, but naively, I can't think of a major obstacle to
pulling this off! When I first ordered my iPAQ, there was no sign of
Sun directly supporting Win CE, but that's history.
(Herzberg seems to be snoozing, so I can't update myself on your archives....)
On another subject, I've got a new project going on qual simulations
for pathophysiology modeling, and I hope to be able to share some
results in the next few months.
Have happy holidays and a prosperous new year for you and your family.
Thanks.
