Hello, Ed.

I try to create Structure object and put in some integer data. But I
have an empty Netcdf file as a result. Here is my sample code. Could
you tell me where is my mistake:

public static void main(String[] args) {
       try {
           NetcdfFileWriteable ncFile = new 
NetcdfFileWriteable("e:\\tmp\\ncstruct.nc", false);
           ncFile.addRecordStructure();
           Structure structure = new Structure(ncFile, null, null, 
"structure_name");

           Dimension dim = Dimension.UNLIMITED;
           dim.setName("dim1");

           Variable var1 = new Variable(ncFile, null, structure, "var1");
           ArrayList dimList = new ArrayList();
           dimList.add(dim);
           var1.setDimensions(dimList);
           var1.setDataType(DataType.INT);

           ArrayList varList = new ArrayList();
           varList.add(var1);
           structure.addMemberVariable(var1);

           ncFile.finish();
           ncFile.create();

           StructureMembers members = structure.makeStructureMembers();
           ArrayStructureW asw = new ArrayStructureW(members, new int[]{3});
           ArrayStructureW.StructureDataW sdata = asw.new StructureDataW();

           ArrayInt.D0 array = new ArrayInt.D0();
           array.set(1);
           array.set(2);
           array.set(3);
           sdata.setMemberData("var1", array);

           asw.setStructureData(sdata, 0);

           ncFile.flush();
           System.out.println(ncFile.toString());
           ncFile.close();
       } catch (IOException e) {
           System.out.println(e);
       }
   }


P.S. I can't find detailed information about how to write netCDF files
in Java. Do you have manuals besides JavaUserGuide in PDF and Java
NetCDF API?
