Hello,

I am trying to serve local netCDF files through the agg
server and access
them through the DODS API.  It is not working.

Have you installed a DODS server and link these netCDF files to this server? According to this configure file the serviceType is DODS, you need a DODS server. AGG server is
based on DODS server, hope this will not confuse you.

Hi Yuan,

I am running this on a Win2k laptop and am not aware of another DODS
netCDF server for this platform. I was lead to believe that the dodsC AS would perform the function of a DODS netCDF server.
Is this not true?  How can I serve netCDF files through DODS from
my laptop?

This is important for taking this technology on the road for
presentations at workshops and conferences.

Regarding confusion, I admit that I am confused by the examples
presented at:

http://my.unidata.ucar.edu/content/projects/THREDDS/tech/dodsAS/AggServerConfig.html

Example 6 suggests that the AS can serve local netCDF files as
DODS data sets.  (Replacing the "..." at the beginning of this XML
snippet with actual tags would be helpful.  Also, it'd be nice
to be more explicit about the differences between examples 3 and 6.)

Ok, so what you need is a netCDF type service. I think your config is ok, but you confused the dataset name and urlpath, dataset name is only the one you want to see on browser, and the
urlpath need to have the dataset real file name there.

Here is the contents of my dodsC/catalogConfig.xml file:

<!DOCTYPE catalog SYSTEM
"http://www.unidata.ucar.edu/projects/THREDDS/xml/AggServerCat
alog.dtd">
<catalog name="THREDDS - DODS Aggregation Server Catalog"
version="0.6" xmlns="http://www.unidata.ucar.edu/thredds"; xmlns:xlink="http://www.w3.org/1999/xlink";>
        <dataset name="AUVCTD mission netCDF files" serviceName="this">
                <service name="this" serviceType="DODS" base=""/>
<service name="local" serviceType="NetCDF"
base="file:///C:/iagdata/ssds/data/auvctd/missionnetcdfs/"/>
<dataset name="Non-Aggregated Netcdf Files"
dataType="Grid" serviceName="this">
                        <property name="internalService" value="local"/>
<dataset
name="2004/2004029/2004.029.03/parosci.nc" urlPath="2004/2004029/2004.029.03/parosci.nc"/>
                </dataset>
        </dataset>
</catalog>

It validates and passes the debug test, yet when I click on
any of the DDS or DAS
links I get this in my browser:

kDODServlet ERROR:
dods.servlet.DODSServlet.getDataset(Ldods/servlet/ReqState; Ldods/servlet/GuardedDataset;
I don't see any helpful messages in the log files.

What am I doing wrong? Even some suggestions as to how I may do my own debugging
will be helpful.
