[jhguo],
If you are referring to the old Palm overlay package (j2me_cldc-1_0_2-fcs-kjava_overlay.zip), it is no longer available for the CLDC 1.0.3 package. It was an old unsupported package and moreover not part of the CLDC 1.0 specification.
If you are looking for the Java virtual machine runtime implementation for the Palm OS, we strongly recommend you to use the MIDP for Palm OS package found at:
