Subject: Help getting THREDDS going
Organization: UCAR/Unidata
Keywords: 200511162245.jAGMjh7s018557
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>
Okay, I stuck the "metadata" section you show above into my file and
restarted tomcat, but it's still failing with the same errors. Any
other ideas? I'm using tomcat 5.0.28 and j2sdk1.4.2_10. Also, I
tried running the catalog.xml file without the "service name" and
"dataseetScan" elements (i.e. essentially empty file) for testing,
and the catalog.html page then comes up properly, although empty (as
would be expected).
Thanks.
Art.
What I would do next is to download and run the development version
(3.3), which will give you an error message instead of throwing an
exception. A number of other bugs are fixed and we are on the verge of
making it the stable release.
get latest thredds.war from
http://www.unidata.ucar.edu/projects/THREDDS/tech/index.html#TDS
Okay, I put the thredds 3.3 war file in webapps and restarted tomcat,
and it seems to have picked it up. Then, after staring at the example
catalog.xml file that came with the package for awhile (and which
worked), I was able to craft my own additions which also worked. The
trick seemed to be in using the "dirLocation" parameter instead of
"scanDir" which seemed to not work.
yes, scanDir has been replaced by dirLocation. Are there some examples/docs
that still use sccanDir ?
also, get Remote Management working by following this page:
http://motherlode.ucar.edu:8080/thredds/docs/RemoteManagement.html
I set up remote management, but when I try to log on as a tdsConfig
user, the page comes up saying "HTTP Status 403 - Access to the
requested resource has been denied", and then below that it says
"message: Access to the requested resource has been denied" and
"description: Access to the specified resource (Access to the requested
resource has been denied) has been forbidden." Note: I AM able to log
on as admin and do status etc... okay.
Any ideas how to get past this? I believe I've done everything on the
remote management setup page referenced above.
its tricky debugging the SSL stuff. If you can give us remote access, we could
poke around a bit.
is your server public?
Thanks.
Art.
there are various debugging things that will help. If you give us a
password, we can help you debug remotely. (but i will be gone all next
week).

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?
