Hi THREDDS Folks,
After much fine-tooth combing, I'm still not having any luck adding a new
dataset to our TDS for the NCOM global ocean model. My catalotInit.log does
not indicate any problems for this catalog either. The only thing that I can
think of that differs compared to my existing FMRC collections is that this
dataset uses longitudes of 0 to 360 rather than -180 to 180: is that a
problem or not allowed? I wouldn't have guessed so. When attempting to
access the catalog page for this FMRC (click on "NCOM Global Ocean Model" at
http://oos.soest.hawaii.edu/thredds/idd/ocn_mod.html), the only thing I can
find in threddsServlet.log is the following:

I have placed logs, my catalog file, and an example NetCDF data file
(zipped) in the following anonymous ftp directory:

ftp ftp.soest.hawaii.edu
user: anonymous
pass: <your e-mail address>
cd jmaurer/thredds/

Thanks in advance for your help!,
