[thredds] thredds's netcdfsubset service

Hi all,

I have an experimental thredds server accessible at 
http://odin.meteo.mcgill.ca:8080/thredds/catalog/testAll/catalog.html.

I am trying to have the netcdfsubset access working for some test dataset, 
http://odin.meteo.mcgill.ca:8080/thredds/catalog/testAll/catalog.html?dataset=testDatasetScan/adj_st_lat20.0_50.0_lon-90.0_-20.0_196012%28smaller%29.nc
but the default netcdfsubset page does not display.

For reference, I have included the threddsConfig.xml and catalog.xml.

Regards,


Stephane
