Subject: Help getting THREDDS going

Hi...
I'm trying to get a basic thredds server going using a simple
configuration but am having trouble. Here's my
$tomcat_home/content/thredds/catalog.xml:
<?xml version="1.0" encoding="UTF-8"?>
<catalog name="PSU Meteorology Department Data Archives"
xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";
xmlns:xlink="http://www.w3.org/1999/xlink";>
<service name="Test" serviceType="HTTPServer" base="" />
<datasetScan name="Model Data" path="model_archive" scanDir="/data/test/" />
</catalog>
You need to tell datasetScan which service to use:
<datasetScan name="Model Data" path="model_archive" scanDir="/data/test/" >
<metadata inherited="true">
<serviceName>Test</serviceName>
</metadata>
</datasetScan>
/data/test/model_archive contains:

In $tomcat_home/logs/catalina.out, I see:

http://server.meteo.psu.edu:8080/thredds/catalog.html gives:
Catalog http://server.meteo.psu.edu:8080/thredds/catalog.xml has fatal errors:

One question I have is whether I need some other server running besides
tomcat/thredds to get this going (e.g. apache or DODS)...? I guess I'm
just expecting thredds to list the data files when I give it the above
catalog.xml file... What am I doing wrong?
