Hi,
I'm new to NetCDF/Thredds and have gone through the initial documentation
provided. I'm trying to use the NetCDF subset service to try and get a
subset of data from a netCDF file by requesting a THREDDS server. However,
this is just not happening. Below is the catalog.xml -
<?xml version="1.0" encoding="UTF-8"?>
<catalog name="THREDDS Server Default Catalog : You must change this to fit
your server!"
xmlns="
http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";
xmlns:xlink="http://www.w3.org/1999/xlink";>
<service name="multiService" serviceType="Compound" base="" >
<service name="thisDODS" serviceType="OpenDAP" base="/thredds/dodsC/" />
<service name="thisNETCDF" serviceType="NetcdfSubset"
base="/thredds/ncss/grid/" suffix="/dataset.html" />
</service>
<datasetRoot path="test" location="content/testdata/"/>
<dataset name="Test Another Single Dataset" ID="testDataset1"
serviceName="multiService"
urlPath="test/RUN_2007-09-17T18-00-00Z.nc"/>
<datasetScan name="Test all files in a directory" ID="testDatasetScan"
path="testAll" location="content/testdata/">
<metadata inherited="true">
<serviceName>multiService</serviceName>
<dataType>Grid</dataType>
<dataFormat>GRIB-1</dataFormat>
</metadata>
</datasetScan>
<catalogRef xlink:title="Test Enhanced Catalog" xlink:href="
enhancedCatalog.xml" name=""/>
</catalog>
** the form is shown appropriately from where I can select the lat/long and
grid variables. Further, after I select and SUBMIT the form, I get a dialog
to save the .nc file. However, the contents of the saved .nc file contains
an error instead of the data**

** On checking the threddsServlet.log, I see the following **
2007-09-19T12:20:28.922 -0500 [ 1170408][ 29] INFO -

thredds.servlet.ServletUtil - Request Completed - 404 - 0 - 2313
The 404 error indicates the requested object is not available. I have no
idea why this is coming, since the dataset.html is being shown properly but
not this.
** P.S: If I use the OPENDAP access, everything works absolutely fine**
Please let me know and provide insight so that I can get it working. I
really need it badly.
Thanks,
