File Error in Excel file while using POI.jar

["Kumaresan, Vinodh" <vi...@merck.com>]

Hi,

I am using POI.jar file to generate an Excel file from my Java based web
application. When I opened the Excel file, for each sheet its showing a
dialog box which has the information "File Error: Data may have been
lost". When I click the ok button a cell which contains data is being
replaced by the value "1024".

We have Microsoft Patch named "Microsoft Office Professional Edition
2003, Security Update for Excel 2003(KB951548):EXCEL". When I removed
the above patch, I was no more able to find the "File Error: Data may
have been lost" error. When contacted Microsoft about the issue, they
suggested to check with 3rd party about the resolution. 

I tested with the latest version of POI.jar which is 3.1 but still
received the same error. 

Can anyone please let me know to get rid of the above issue.

Thanks,
Vinodh

Sounds like Microsoft changed something unhelpful with that patch. Were 
they able to tell you what they did change?

Did you try with a recent svn trunk checkout / svn nightly build, to see 
if the problem has been fixed since 3.1 final?
