I tried joining the netcdf-java mailing list using the on-line form,
but got no results emailed back to me...so I'm writing directly (sorry).
I'm trying to write my very first netcdf file from scratch using
netcdf-2.2.jar. Just as I'm starting, I'm testing and it's throwing
an interesting exception. I'm sure it's "Pilot Error", but I have no
clue at this point.
I'm using the current netcdf-2.2.jar file from the web site.
Here's the code (sorry it's in Jython, but that's what we're using
these days -- if it turns out to be some data type conversion
problems, then I'll have to find a way around that, but when I look at
"DataType.LONG" it prints a "long" and is a class ucar.nc2.DataType):
from ucar.nc2 import NetcdfFileWriteable
from ucar.nc2 import DataType
def makeNetCDFtest():
ncfile = NetcdfFileWriteable()
ncfile.setName("mydata.nc")
oneDim = ncfile.addDimension("one",1)
ncfile.addVariable("date", DataType.LONG, [oneDim,])
ncfile.addVariableAttribute("date","long_name","Date, in YYYYMMDD
format")
ncfile.create()
ncfile.close()
if __name__ == "__main__":
makeNetCDFtest()
print "done..."
Here's the exception:
raceback (innermost last):
File "<string>", line 19, in ?
File "<string>", line 15, in makeNetCDFtest
java.lang.IllegalStateException: unknown DataType == long
