Re: [las_users] LAS error when using curvilinear grid

["John Maurer, IV" <jmaurer@xxxxxxxxxx>]

Hi Phil,
It was a good thought, but that URL is valid and works for my other datasets, like WRF. oos.soest.hawaii.edu is our proxy to lawelawe.soest.hawaii.edu:8080. Urls of the latter form are not accessible outside of our firewall but are the required form for lawelawe to call LAS services of itself. Actually, this is something I recently worked out with Roland: using urls with our proxy (oos) in productserver.xml were not working.

So, any other ideas why NCEP is giving me this strange error message? The same set-up worked in LAS6/Ferret6.1 but no longer works in LAS7/Ferret6.5.

Thanks,
John

That TDS doesn't seem to be working.  The TDS address that you give later is working though...

Check the url attribute that you have for the variable would a starting point.  If that is set correctly there may be an incorrect url attribute in productserver.xml.

Hi All,
