Hello,
I am really new to the netcdf-java library.
I am really stuck on getting the forecast times from a grib file.
Anything else works great (getting the lat/lon coordinate points,
getting the values or subsetting the grid...).
I tried the following:
------------------
String filename = "current.grb";
FmrcImpl forecasts = new FmrcImpl(filename);
List<Date> forecastDates = forecasts.getForecastDates();
for(Date d : forecastDates){
System.out.println(fd);
}
-----------------
But the above fails with a nullpointer exception on Object creation
(FmrcImpl forecasts = new FmrcImpl(filename);):
---------------------
Exception in thread "main" java.lang.NullPointerException
at ucar.nc2.dt.fmrc.FmrcImpl$Gridset.<init>(FmrcImpl.java:264)
at ucar.nc2.dt.fmrc.FmrcImpl.init(FmrcImpl.java:133)
at ucar.nc2.dt.fmrc.FmrcImpl.<init>(FmrcImpl.java:85)
at ucar.nc2.dt.fmrc.FmrcImpl.<init>(FmrcImpl.java:81)
at Test.main(Test.java:62)
---------------------
Please can anybody help me on this?
Best regards,
Alex
