[THREDDS #JRP-282661]: Fwd: WMS in THREDDS 5



Oops...here is the attachment.

> Greetings Alan,
> 
> The reason I had you try with the vanilla TDS war and and simple example
> was to see if we could even access WMS on your server, or if there was
> a potential issue outside of the TDS (maybe Tomcat, Apache, etc). Given
> that the simple test works, it looks like the issue is related to a difference
> in the esgf bundled TDS.
> 
> There are two things I'd like to try now.
> 
> 1) Try the aggregation with the vanilla TDS by adding the following
> to the main catalog.xml (the one with the simple datasetScan that works):
> 
> <dataset ID="Aggtest"
> name="AggTest"
> urlPath="AggTest">
> 
> <metadata>
> <dataType>GRID</dataType>
> </metadata>
> 
> <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
> <aggregation dimName="time" type="joinExisting">
> <variableAgg name="cee"/>
> <variableAgg name="cee_corr_unc"/>
> <scan location="/neodc/esacci/cloud/data/phase-2/L3C/AVHRR-PM/v2.0" 
> suffix=".nc"/>
> </aggregation>
> </netcdf>
> </dataset>
> 
> between the </datasetScan> and </catalog> entries at the end of the 
> catalog.xml file.
> Note I've attached an updated copy of catalog.xml with the changes in case 
> the xml
> snippets above do not show up in this message. Check to see if things still 
> work in the first
> dataset, and then see if they work with your aggregation. Try hitting the 
> opendap link
> of your aggregation dataset first to make sure it does not return a 404 or 
> 500.
> 
> 2) Can you send me the thredds/WEB-INF/web.xml file from the webapps directory
> included with the ESGF distribution?
> 
> Thanks!
