<p>Does anybody have experience of a decent J2SE (preferably at least Java JDK 1.5-level) Java Virtual Machine for Windows Mobile 6? If you know of any CLDC VMs, I'm also interested because even that would be better than what we <a href="http://www.nsicom.com/Default.aspx?tabid=138" rel="nofollow noreferrer">currently have</a> for the platform. </p>

Honestly I searched a while and there no decent JVM for windows mobile. The best bet I think is this :

but it's JDK 1.3 compliant the last time I checked.
