Hi,

Version: POI 2.5
Weblogic:8.x

I am exporting data to an excel file successfully
using POI, once data is exported I am trying to upload
the exported file. But in doing so it throws an
exception saying: 
"IOException Unable to read entire block; 49 bytes
read; expected 512 bytes".

But if I do minor data modifications to the excel
file(in Ms-Excel) and then saving the file: uploads
the data successfully.

Even if we did not do any modifications but just
opening the excel file(in Ms-Excel) and saving the
file is also able to upload the data successuflly.

Any suggestions please!
