Hi!

I don't think so. There is no unique VM availale to that variety of platforms.

The big problem is to get a VM that runs under those platforms. There is one kind of VM available to PDAs - personal Java -, other to notebooks and PC's - J2SE -, other to Palm devices - J2ME CLDC MIDP-.

3 VM to three kind of devices with different features, although the Personal Java apps probabily would be compatible with J2SE...

Is the quote "Write once run anywhere" only true if those different platforms are using the same virtual mechain?

Yes, you're right. It's basically down to the VM the client device is using. So a user interface written for MIDP isn't going to work too well on a PersonalJava VM.
