Hi Aleksander,

There are a few issues with your catalog:

1. You need to define a datasetRoot element.
2. The netcdf element is used to define a NetCDF file inline (within the
catalog). You don't need it.
3. Instead, point to your existing NetCDF file using the combination of
datasetRoot and urlPath.

Try something like this instead:

<datasetRoot path="test-data"
location="/opt/tomcat/content/thredds/testdata/" />

<dataset name="TestDataset" ID="test" urlPath="test-data/testfile.nc">
    <metadata inherited="true">
        <serviceName>testservices</serviceName>
        <dataType>Station</dataType>
    </metadata>
</dataset>

Also, take a look at our THREDDS Configuration Catalogs tutorial [1].
Hopefully that'll get you sorted.

Cheers,
Christian
