Re: J2ME on Nokia 770

We could really use some direction from Nokia here.
Jamvm, SableVM, GIJ, maybe even ikvm, could all likely be made to work=20
with a subset of gnu classpath to implement CLDC 1.1 and a hildon based=20
MIDP 2.0
But if we really want to run java effeciently, we should use the Jazelle=20
hardware on the ARM chip. This part is not free and would require Nokia=20
to put out the jvm.
There is no reason Nokia couldn't put out the jvm and use it along with=20
open source class libraries.
