Hi,
In my application, I am trying to read an excel sheet which weighs 5.61 MB.
I am using the poi-3.2-FINAL-20081019.jar file. The following are the codes :
My problem is, I am getting the following errors.
My code starts like this :

FileInputStream fileIn = new FileInputStream(properties.getExtractFilesPath() + "mailinglist_extract.xls");
POIFSFileSystem fs = new POIFSFileSystem(fileIn);
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);

Iterator<HSSFRow> it = sheet.rowIterator();

while (it.hasNext())
{
HSSFRow row = (HSSFRow) it.next();
""
""
(And the Loginc continues)
...
...
}

I got the following set of errors..!
