Hi Harbil,
When you serve remote datasets, you don't need to add them to the catalog (at
least, I think that's true). The URL is itself a WMS endpoint. So if you have
remote datasets enabled, you can point your WMS client to the URL:
http://localhost:8080/thredds/wms?dataset=http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/godas/dbss_obil.1984.nc
and it should work.
If you want to add a remote dataset to the catalog you probably have to do
something different.
(Someone who knows more about THREDDS than I do will hopefully correct me if
I'm wrong!)
HTH,
Jon

Hello everyone,
I apologize in case I'm asking this in the wrong place. I have setup a Thredds
server and I'd like to offer WMS access to several remote datasets.
This remote datasets are given in OPENDAP and HTTPServer.
I cannot make the method shown
here<http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.2/reference/WMS.html>work.
In catalog.xml I put:
<dataset name="Remote" ID="dbss_obil" serviceName="wms" urlPath="
http://localhost:8080/thredds/wms?dataset=http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/godas/dbss_obil.1984.nc";
dataType="Grid"/>
I already changed the threddsConfig.xml file including:
<WMS>
<allow>true</allow>
<allowRemote>true</allowRemote>
</WMS>
It gives me this error:
<ServiceExceptionReport version="1.3.0" xsi:schemaLocation="
http://www.opengis.net/ogc
http://schemas.opengis.net/wms/1.3.0/exceptions_1_3_0.xsd
"><ServiceException>
Failed to open dataset, "
http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/godas/dbss_obil.1984.nc?service=WMS
".
</ServiceException></ServiceExceptionReport>
So, am I trying to do something non-sense, expecting that my server should be
able to do the direct conversion from the remote .nc file to WMS? Is there any
way to do this?
Many thanks,
Harbil
