There is a thing called "jump" that is supposed to allow you
to write programs in java that run on the palm pilot. Here is
an example program for you.
---------------------------------
import palmos.*;

class Hello {
static final int idfMain = 1000;

public static int PilotMain(int cmd, int cmdBPB, int launchFlags)
{
if (cmd != 0) {
return 0;
}

Palm.FrmGotoForm(idfMain);

Event e = new Event();
ShortHolder err = new ShortHolder((short)0);
while (e.eType != Event.appStopEvent) {
Palm.EvtGetEvent(e, -1);
if (!Palm.SysHandleEvent(e)) {
if (!Palm.MenuHandleEvent(0, e, err)) {
if (!appHandleEvent(e)) {
Palm.FrmHandleEvent(Palm.FrmGetActiveForm(), e);
}
}
}
}
Palm.FrmCloseAllForms();
return 0;
}

static boolean appHandleEvent(Event e)
{
if (e.eType == Event.frmLoadEvent) {
int form = Palm.FrmInitForm(e.formID());
Palm.FrmSetActiveForm(form);
return true;
} else if (e.eType == Event.frmOpenEvent) {
Palm.FrmDrawForm(Palm.FrmGetActiveForm());
return true;
}
return false;
}
}
