Hi,
Well the Nokia maemo team won't care until they get a product
program that requires Java (that's my hunch :-)
Yes, there is no reason they wouldn't do it, and we all await Nokia
Maemo's coming to Java. They might be waiting for the community to put
up all the basic work in the mean-time though...
It all depends whether they go for MIDP or OSGI, or both. OSGI requires
CDC, whereas MIDP only requires CLDC. But with such a screen size (and
probably future ones as well), they can do much better than just MIDP.
Then there is also the enabling of Hildon apps dev in Java.

We could really use some direction from Nokia here.
Jamvm, SableVM, GIJ, maybe even ikvm, could all likely be made to work
with a subset of gnu classpath to implement CLDC 1.1 and a hildon
based MIDP 2.0
But if we really want to run java effeciently, we should use the
Jazelle hardware on the ARM chip. This part is not free and would
require Nokia to put out the jvm.
There is no reason Nokia couldn't put out the jvm and use it along
with open source class libraries.

Hi,
I have just joined this list so please forgive whatever sounds
ignorant.
For the choice of VM I would recommend SableVM, as with its recent
refactoring I built it down to 220 K on Intel with gcc -Os etc.
Check out SableVM at www.sablevm.org.
We at Gatespace are the people behind Knopflerfish OSGI. I test-drove
Knopflerfish's test suite with JamVM and SableVM (both use
Classpath), the results were the same, and the speed was comparable.
Haven't measured memory consumption yet. We target CDC, so our
constraints with respect to that are less strict.
Classpath's AWT of course runs on top of GTK+.
I argue for Sable instead of Jam because:
- Sable has a large and active community
- Sable is LGPL. GPL does not work for maemo. Read why at
http://sablevm.org/wiki/License_FAQ.
- Sable has an almost complete JIT compiler.
Someone needs to put in a build option to Classpath to make it build
CLDC only, or any other profile.
As for the MIDP implementation, someone is working on it (announced
on the wishlist).

Right. Most work for that port would be in:
- choosing JVM,
- create CLDC implementation,
- create graphics support (MIDP part) to GTK+.

Sound fine. But you will not get far without a Java environment /
JVM, which is exactly what we are missing on the Nokia 770. I been
having plans for implementing a CLDC JVM on the 770 but I have
been waiting for somebody to make 770 development on Mac OS X
possible. I don't think it is possible yet.

Hello,
I've read some discussion on that list about the possibility of
running
J2ME MIDlets on Nokia 770. As I've found, the problem is because of
lack of J2ME implementation for that device. I'm an author of
MicroEmulator (http://www.sf.net/projects/microemulator) - pure java
CLDC/MIDP implementation. I think it would be possible to create port
of MicroEmulator on Nokia 770 to fill that gap. If anyone is
interesested in that please send info and I could look into more
deeply.
