Hi, I am in the team implementing the Live Access Server for the Meteorology Laboratory of the Federal University of Rio de Janeiro here in Brazil. We were successful in instaling and populating our LAS (Revision r3974) but when applying any analysis we kept getting the following error (on any datasets including the COADS sample) , debugging we found out that the problema was that he was using SET DATA in a journal. **Internet Data error
OPeNDAP Error: Error parsing the text on line 1 at or near: Error
The descriptor object returned from the dataset was null.
Check that the URL is correct.
(OPeNDAP/netCDF Error code 1001)

Can anyone help us with this ? Thanks in advance. Eduardo Szrajbman Vaz da Silva Laboratory of Applied Metheorology Federal University of Rio de Janeiro - Brazil |
