Hi List,

I´m using geoserver 2.8 with netcdf plugin. I am creating a store with netcdf file and I get the following error:

“Could not list layers for this store, an error occurred retrieving them: Failed to create reader from file://Z:.…\26012016.nc and hints null.”

Is there a problem with the file?

Attached you find a file extract from the .cdl file.

netcdf 26012016 {

lon = 42 ;

time = 7 ;

Hi Lotta,
do you have any chance to share the full log?
Which version of GeoServer are you using? (2.8.x, X = ?)

I have a doubt in relation to the time unit.
I think that the current code only deals with “seconds/minutes/hours/days since the reference time”.
I’m not sure it will support the “years since date” type.

Let’s see if the log says something more to provide you more feedbacks.
Hope this helps.

Cheers,
Daniele

Hi Daniele,

the GeoServer Version is 2.8.1

After a few tests, my conjection is also the time unit, even if you have a look to the logfile.

Are there any hints how I can skirting it?

Cheers

Hi,
without modifying the code, the quickest approach you may consider is:

  • rewriting your NetCDF to use a more common time unit as the one reported in my previous email
  • using NCML to update the time variable (this approach is less invasive since you won’t modify the original data, you will just place a .ncml file beside your sample containing a few instructions to describe the updated time dimension): https://www.unidata.ucar.edu/software/thredds/v4.5/netcdf-java/ncml/Cookbook.html.
    (just overwriting the “units” attribute value and the time instant values in the proper unit).

Supporting your sample as is, would require some code changes.
In that case, you can consider opening a JIRA containing the sample data and details on the issue to report the problem.

You can contribute yourself the improvements through a github pull request or just wait for a developer taking care of this issue.

Hope this helps.
Cheers,
Daniele

Hi Lotta,
do you have any chance to share the full log?
Which version of GeoServer are you using? (2.8.x, X = ?)

I have a doubt in relation to the time unit.
I think that the current code only deals with “seconds/minutes/hours/days since the reference time”.
I’m not sure it will support the “years since date” type.

Let’s see if the log says something more to provide you more feedbacks.
Hope this helps.

Cheers,
Daniele

Hi List,

I´m using geoserver 2.8 with netcdf plugin. I am creating a store with netcdf file and I get the following error:

“Could not list layers for this store, an error occurred retrieving them: Failed to create reader from file://Z:.…[26012016.nc](http://26012016.nc) and hints null.”

Is there a problem with the file?

Attached you find a file extract from the .cdl file.
