error reading excel file using apache poi

[Priya Bhagat]

I am trying to read data from excel file but it is giving me the following error:

Exception in thread "main" org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. POI only supports OLE2 Office documents
at org.apache.poi.poifs.storage.HeaderBlockReader.<init>(HeaderBlockReader.java:108)

at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>(HSSFWorkbook.java:293)
at Test.displayFromExcel(Test.java:46)
at Test.main(Test.java:28)

I am using Apache HSSF-POI version 3.2-FINAL-20081019.
My file has .xls extension.
Any idea what's wrong?

POI apparently suspects that it is not an XLS file, but an XLSX file - is it? If so, you need to use the POI 3.5 beta version (which supports Office Open XML - something POI 3.2 does not do).

Hi Dittmer,

Thank you for your reply. Actually i wasn't using a correct file type. I was appending .xls extension to an Open Office org file preveously so only it was giving that error.
I tried with a MS-Excel (2003) file then it's working fine.
