Re: 20020709: Exception in thread "main" java.lang.IllegalArgumentException

You have to first create the variable, eg:

  NetcdfFileWriteable ncfle = new NetcdfFileWriteable();  // from netHead
  ncfle.setName(outfle);                  // output file name

    // define dimensions
    Dimension netOut_nStrings = ncfile.addDimension("netOut_nStrings", 2);
    Dimension netOut_strLen = ncfile.addDimension("netOut_strLen", 10);

    // define Variable "netOut"
    Dimension[] dims = new Dimension[2];
    dims[0] = netOut_nStrings ;
    dims[1] = netOut_strLen ;
    ncfile.addVariable("netOut", char.class, dims);


  try {
    ncfle.create();                           // create CDF binary file
  } catch (IOException e) { System.out.println("ERROR creating file"); }

if you look at the user manual, it has some complete examples
