Sorry it took me a while to get back to this. The failure is at the line
that reads:
wb = new HSSFWorkbook(fs);

In the following debug session, the failure is at line 1543 (Please bear
with me; this is not an RPG question). I would appreciate guidance.

What line of code in loveladyTest is line 21? It's telling you
something
somewhere is null.

Happy Monday!



I've been using the POI 3.2-FINAL objects for quite a while on a
few
systems, and have now run across a problem for which I find no
solution; I
wonder if I might get some guidance from this list.



I can open, read and digest all the rows and cells on one
particular
spreadsheet on a V5R3 system. But when I move that same
spreadsheet
to a
V5R4 system, I receive the subject message (stack trace below). To
isolate
the cause of this issue, I used a simple JAVA program (source
below)
and
ran
it on the same (failing) system, and received the same failure. I
did
check
all the normal stuff (like ASCII-mode FTP, et cetera), and I find
no
problem. I can FTP that same file back to the V5R3 system, and
process it
without problem. I wonder if this might be the result of some
configurable
parameter within iSeries Java, but am at a loss as to what to
tweak.



One last thing: the V5R4 system is capable of reading other
spreadsheets
I've tried without issue. I don't want to bring this to the POI
community
(yet) due to the suspicion that this is an iSeries-specific or
configuration-specific issue.



Would appreciate any help.
