Hi,
I am investigating the use of the java netcdf API for serving our data. We
have scalar time-series data from stationary instruments, data from mobile
platforms, and complex data stored in a db and files on an archive server. I’m
trying to determine if it is possible and relatively simple to write a service
using the Java API to respond to OpenDAP requests. I can write the NetCDF
files easily enough; but not sure if I can simply respond with them, or whether
I would have to write the data to a temporary location and have some external
service serve them from there.
Could you please point me in the right direction for this investigation? Other
possibilities we are investigating are the use of Hyrax and the use of ERDDAP
to serve netCDF files and tabular data.
Thanks in advance for your insights!

Thanks, Brian.
Those classes all contain various methods for writing to NetCDF files, but none
appear to
have a 1:1 correspondence
to the functionality you got from the now deprecated FileWriter.writeToFile()
method, at least from what I can tell (the JavaDoc is sparse
,
at best). From what I can tell one way to go about it
is
to use the FileWriter2 constructor
and
then
its
write() method,
like so:
FileWriter2 fileWriter = new FileWriter2(netcdfDataset, outFilePath,
NetcdfFileWriter.Version.netcdf3, null);
NetcdfFile outNetcdfFile = fileWriter.write();
The above seems to work just fine. Is this the reasonable/recommended way to
do things now?

Hi James,
I believe the current functions for this purpose are
http://www.unidata.ucar.edu/software/thredds/v4.3/netcdf-java/v4.3/javadoc/ucar/nc2/NetcdfFileWriter.html
or
http://www.unidata.ucar.edu/software/thredds/v4.3/netcdf-java/v4.3/javadoc/ucar/nc2/FileWriter2.html
or
http://www.unidata.ucar.edu/software/thredds/v4.3/netcdf-java/v4.3/javadoc/ucar/nc2/dt/grid/NetcdfCFWriter.html
depending on your needs, assuming you are using 4.3.
Cheers,
Brian

Subject: [netcdf-java] Deprecated class/method (FileWriter.writeToFile()), any
guidance as to what else I should use?
The method FileWriter.writeToFile(NetcdfFile,
String
,
boolean)
is marked as deprecated in the JavaDoc, and shows as such in Eclipse. I'd
like to use an appropriate/non-deprecated method for this, but the JavaDoc
gives no guidance as to what that might be. My use case is that I have a
NetcdfDataset that I want to write to file.
Can anyone advise? Thanks in advance for any suggestions.
