RE: Using Java in RPGLE - cell comments and document properties

I'm not sure how you'd do that in RPG. In Java, you check:

InputStream myxls = null;
HSSFWorkbook wb = null;
HSSFSheet sheet = null;
HSSFRow row = null;
HSSFCell cell = null;
String fileName = "my.xls";

myxls = new FileInputStream(fileName);
wb = new HSSFWorkbook(myxls);
sheet = wb.getSheetAt(0);
myxls = new FileInputStream(fileName);
row = sheet.getRow(0);

boolean validFormat = true;
cell = row.getCell((short) 0);
if ((cell == null) || !cell.getStringCellValue().equalsIgnoreCase("Author/s")) {
    validFormat = false;
}

This code (the last 5 lines) checks to make sure the first cell in the first 
row contains the text "Author/s".

How do I do that without extracting the value first?  That's where it blows:

cell = HSSFRow_getCell(row: 2);

Maybe HSSFRow_getCellType?  And look for value CELL_BLANK?  The
HSSFSheet_getRow didn't get an error, and I believe the entire row was null.
