THREDDS:
I've adjusted the CDL in the NetCDF files of interest so that the time
is the slowest varying dimension. And I have started small (with 6
instead of 6000) files.
Watching the logs I made sure there wer no errors/warnings associated
with this dataset entry:
When I goto the OPeNDAP Service link on this page:
http://nomads.ncdc.noaa.gov:8085/thredds/testDatasets.html?dataset=test/BOWdailyagg2
The following Java exception appears in threddsServlet.log:
===========================================================================
<dataset name="Blended Ocean Winds Test Daily Aggregation II"

<scan dateFormatMark="#yyyyMMdd" location="/raid/seawind-test/"

What am I doing wrong?
Is this more likely a problem with the configuration file or with the
data files?
