Hi guys,
A newby question: I have a device(ARM CPU) here with only 30mb of RAM.
I started looking for J2ME implementations; but their doc said I'd need 128mb minimum! Is that really the case? I cannot image all GSMs running JME having 128+ mb.

Or would I be better of turning to an older JME version with only 30mb RAM?
Can someone advice me what to do/use?

Appreciate all advice,
-Wolf

I don't know where you got your numbers, but my phone only has something like 32MBRAM+32MVNVRAM and I got the IBM J9 JVM running on it.

For really constrained environments, there was a well-known JVM that ran in only 16KB, back when a 2MB Palm device was "big". Unfortunately, I'm too senile to remember what it's called. Not J2ME complaint, but at least it brought Java to seriously memory-constrained systems.

Hi Tim, seems IBM's J9 is not available anymore.

I think they just hid it very well. I went looking recently.

It is, however, reported to be pretty much dead. Palm was using it until January 2007 when for unexplained reasons they dropped it.
