Java on Handheld Devices?

superfred queries: "I work for a Java-based software company, and have been tasked with researching Java on handhelds...I've managed to dig up information on which handhelds support Java (most of the major ones do), but what puzzles me, is if any company is actually *using* this for any reason (besides Java-based handhelds/phones). The Palm OS has apparently supported Java since the Palm V, but has anyone written any software to take advantage of it? Are there any major software developers working on Java applications for handhelds? It seems like a great deal of effort has been used in getting Java on these platforms, but nothing's really utilizing it."
