[maemo-developers] [maemo-developers] J2ME on Nokia 770

[From: Philippe Laporte]

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).

Best Regards,

Philippe Laporte
