Re: J2ME on Nokia 770

Hi,
     I have just joined this list so please forgive whatever sounds=20
ignorant.

For the choice of VM I would recommend SableVM, as with its recent=20
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=20
Knopflerfish's test suite with JamVM and SableVM (both use Classpath),=20
the results were the same, and the speed was comparable. Haven't=20
measured memory consumption yet. We target CDC, so our constraints with=20
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=20
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=20
CLDC only, or any other profile.

As for the MIDP implementation, someone is working on it (announced on=20
the wishlist).

Philippe Laporte
