Hi,
I would like to get data from a NetcdfSubset using the NetCDF java library.
I made different tries without any success.
I am passing through a proxy and I think the parameter were set correctly.
I tried either with the version 4.1 and 4.2 of the library.
With version 4.1 I used this code:
// Set proxy if specified
if (this.proxyHost != null) {
httpClient.getHostConfiguration().setProxy(
this.proxyHost,
this.proxyPort);
}
NetcdfDataset.setHttpClient(httpClient);
With version 4.2 I used this code:
// Set proxy if specified
if (this.proxyHost != null) {
System.setProperty("http.proxyHost", this.proxyHost);
System.setProperty("http.proxyPort", String.valueOf(this.proxyPort));
}
The URL I use to get the data is:
http://motherlode.ucar.edu:8080/thredds/ncss/grid/fmrc/NCEP/GFS/Global_0p5deg/runs/NCEP-GFS-Global_0p5deg_RUN_2011-04-01T00:00:00Z?var=U-component_of_wind_height_above_ground,V-component_of_wind_height_above_ground,Temperature_height_above_ground&temporal=range&time_start=2011-04-01T00:00:00&time_end=2011-04-08T12:00:00&spatial=bb&south=15.5&north=16.5&west=-62.0&east=-61.0
When I copy / paste this URL on my browser, I am able to save the nc file.
So I do not know I am doing wrong.
I tried both with either:
this.netcdfFile = NetcdfFile.open(filepath);
this.netcdfFile = NetcdfDataset.openFile(filepath, null);
But I get the same error at the end which is:
Cant read

not a valid CDM file.
I also tried with:
NetcdfDataset.initNetcdfFileCache(100,200000,15*60);
this.netcdfFile = NetcdfDataset.acquireFile(filepath, null);
But again I got the same error.
Could somebody tell if what I am trying to do is possible. And if so help me
on how to do it.
Thanks,
Alex
