 Hi,

I was using an old version from Netcdf Java API (ucar.netcdf) to read Netcdf files. Now, I'm doing an uptade in my program and I saw the new version from Netcdf Java API. I'm very interested in the feature "dataset" because this would do easier my job. I read the latest manual and so, I decided to test it. I've got a Netcdf file that follows COARDS convection (It was produced in ferret software), applied ncdump >> resulting in the file .cdl, put the attribute global :Convection="COARDS" in :history header, and finally I've created another nc file with ncgen.

So, in my java program I've wrote these line commands:

try {
Netcdf nc=ucar.nc2.dataset.NetcdfDataset.factory("c:\...\BFOR.nc",null);
NetcdfDataset ds=ucar.nc2.dataset.conv.Convection.factory(nc);
....

}catch(IOException e) {JOptionPane.showMessageDialog(null,"problems !!")} Well, the problem is that the program stopped in the line NetcdfDataset and Everything after this don't work. If I put anything before this line, it works fine. I've also tried with a nc file without Convection attribute and it didn't work too.

Am I doing everything wrong? I need some help. Sorry for my english ...

Thanks in advance

hi viviane:

in general, print error messsages like

try {
Netcdf nc=ucar.nc2.dataset.NetcdfDataset.factory("c:\...\BFOR.nc",null);
NetcdfDataset ds=ucar.nc2.dataset.conv.Convection.factory(nc);
....
}catch(IOException e) {
 e.printStackTrace();

that will tell you what the error is

"c:/.../BFOR.nc"
