java.lang.RuntimeException: Expected an EXTERNSHEET record but got (org.apache.poi.hs

Hi All,

I have developed a Core Java application for converting excel to csv files(in Eclipse galileo) using poi3.5beta2.jar. I'm able to covert excel to csv.

Note: The excel files i am processing are 97-2003 version files.

**************
Yesterday when i was executing a excel file, I got
"java.lang.RuntimeException: Expected an EXTERNSHEET record but got (org.apache.poi.hssf.record.SSTRecord)

*****************
When i tried to debug, i found that
HSSFWorkbook wb = null;
POIFSFileSystem fs = null;
try
{
fs = new POIFSFileSystem(new FileInputStream(excelFile));
wb = new HSSFWorkbook(fs);
}
catch(Exception e)
{
e.printStackTrace();
}

wb in the try block was null and an exception was throw like Null pointer exception.

But when i opened the file and saved the file(without any changes) the size of excel file got reduced, and when i run my application the csv file was generated with out any error...

I have 100+ files which are giving this problems....
So i canot manually try to open and save...

Pls help me...Thanks in Adance....
