There is no standardised Java support for Windows Mobile.

What JSRs are available will depend upon the particular Java runtime you
have installed on your device.

Hope this helps,

Christopher is right. WM devices dont come with Java preinstalled. There are
some JVMs for WM/CE:
IBM J9 (Websphere)
CrEme (used by SAP)
Jeode (Insignia)
WEME (google for this free Java implementation)
SuperWaba(more or less compatible)
..

Interestingly there is no JVM available by SUN (maybe cause M$ always have
there own meaning about standards in the past)

And exactly what does that mean? ALl of the Java JVMs you list (and just
about every one for any mobile device out there) varies a lot in their own
implementation, so it appears to me that the Java community itself has no
"standards" when it comes to mobile platforms. Write once run anywhere with
Java is a pipe dream, as anyone who's tried to do a mobile app that works on
multiple devices could attest.

Windows CE is as standard as any other embedded OS, and you get a vast
majority of the source for it with the tools, so there is no technical
barrier to Sun creating a JVM. Why Sun hasn't done a JVM for Windows CE I'm
guessing has a lot more to do with business and money (yes, even your
beloved non-MS companies some how have to make money as well - amazingly
employees for Sun don't work for free either). The Windows CE market is
small, and there's little monetization in generating and supporting a JVM
for CE. Sun target s the enterprise market, and they've likey determined
that there isn't any business sense in them spending the resources doing the
port.
