Hello all,
I am using the example provided with the POI distribution
(ReadWriteWorkBook.java, below) as a reference. It works fine, but when
I try to port it to XSSF, the final write() statement fails.
The file is created, but seems to be corrupted.
In my next post, I will included the program as modified by me.
TIA,
-Ramon
