Since RC1 is now out. Could you give that a go. There are a large number of
corruption issues that were sorted out in this release over and above pre3.

Subject: Re: unable to open HSSF (generated) excel file

using  poi-bin-2.0-pre3-20030728
platforms- win2k and solaris.

our application queries a DB user-log table  and generates a workbook sheet
that contains 3 columns (plus some header columns). the 3 columns are
"username" "login-time" and "logout-time" all cell values are writted out as
strings. in some cases the workbook generated will not open in MS-Excel
2000. i wrote a test pgm that can recreate the problem consistently, using
the the data from the DB exported into a flat file. the test pgm simply
reads the file and writes to a workbook.

i have noticed that this seems to depend on size. if i run this for records
for the current month only, the report is generated correctly. if i run it
for the whole year, i am unable to open the file. 

i noticed a similar thread in the list and as per the resolution note, i
checked out the latest code from CVS today morning and tried re-running the
test pgm with the latest jars but i get the following exception
java.lang.ArrayIndexOutOfBoundsException

Exception in thread "main"

i can send out the test pgm (which is fairly straight forward) and the input
test file (cannot attach it as the zipped file size is abt 150k). can
someone please help me with the problem?

note - if i try ms-excel 2002, i am able to open the file but i  get an
error dialog saying "errors detected in workbook, but ms excel was able to
open it by making repairs listed below" the repair log says that the repairs
were not possible.

please let me know if i should open this as a bug or i should pose this to
some other mailing list.


thanks,
