I believe that Mike McCann is describing a bug in version 1.3 of the Thredds server. I have xml that works fine in version 0.6, but which fails to serve NetCDF files in version 1.3, even though the catalog.xml file passes the validate test. Using the automatic translation utility does not help either.

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. Yuan 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.) -Mike 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. Yuan 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. -Mike -- Mike McCann Software Engineer Monterey Bay Aquarium Research Institute 7700 Sandholdt Road Moss Landing, CA 95039-9644 Voice: (831) 775-1769 Fax: (831) 775-1646 <http://www.mbari.org/rd/iag.htm>
