Hi,
I encountered a similiar problem as Mathieu. (I did a search on the archives and realised I am not the only one)
Let me state my exact scenario in hopes that my added details will help.
I use POI to create Excel spreadsheets with dynamic data using a template (.xls) file. Previously, I was using and older version of POI [File size: 605 KB (620,262 bytes)] which worked fine. However, I recently upgraded it to POI 2.5 Final, and it started having problems. I been using the same test files for both versions (if anyone want a copy I can send it to you).
What happen is that there was a graphic in my excel which caused the produced Excel file which could not be opened. Also, there was NO exceptions/errors thrown from POI.
Later when I read the below post, I tried to remove the graphic and 'viola' it worked correctly.
Has anyone an idea why this is happening? Any quick remedies?
My system specs: ---------------- OS: Windows 2000 Server JRE: 1.4.1_02-b06 Excel 2000 (9.0.2720)
Regards, Daniel

---------------------------------------------------------------------------- ---- Hi,
my web application creates an Excel sheet with HSSF. It reads first a template file (an xls file) containing a wmf (Windows Metafile) graphic. Sometimes it works fine, if I use a plain wmf (or emf) graphic. But if the wmf is more complex, Excel cannot read the generated file. This error message appears in a pop-up : "Impossible to read the file". It doesn't work either if I use a jpg or tiff graphic.
Where does this issue come from ? Is the wmf file too big ?
For information, I use : - Tomcat 4.1.18 - Windows 2000 - IE 6, Excel 2000
thanks, Mathieu
