[OpenMap Users] Can't see vfp Nautical chart data ?

I am using a VPF layer in my open map application and when I use VMAP data,
everything works fine. If I switch to using nautical charts (DNC), I don't
see anything getting displayed.

I also notice the two directory structures are a bit different.

The NauticalCharts look like this:

Alaska/DNC25/
..various chart dirs
DHT (file)
LAT (file)

The VMAPs look like this:

Northamerica/
FGDC_DAT.txt
VIEW (dir)
VMAPLV0 (dir)
   NOAMER (dir)
   RFERENCE (dir)
   DHT (file)
   LAT (file)

My openmap properties file looks like this:

vpfcache.class=com.bbn.openmap.layer.vpf.LibraryBean
vpfcache.name=VMAPLEVEL0
# this is the VMAP data and it works.
#vpfcache.vpfPath=C:/northamerica/VMAPLV0

# this is the DNC data and it does not work.
vpfcache.vpfPath=C:/AlaskaNautical_charts/DNC25


Has anyone used the DNC's in openmap?

Thanks in advance.
