Re: [smila-dev] Blackboard inconsistency!?
|
Hi Bogdan,
it seems that HSSFWorkbook.getBytes() doesn't work as expected:

Maybe this helps.
Best regards,
Andreas

Betreff: [smila-dev] Blackboard inconsistency!?
Dear all,
I am having some problems using the blackboard for saving attachments.
Namely, I am trying to save and Excel file and having it read back, but
there seem to be some inconsistencies with the stream:
" java.io.IOException: Invalid header signature; read 0x0005060000100809,
expected 0xE11AB1A1E011CFD0"
The code looks like this:
...
blackboard.setAttachment(message.getQuery(), "workbook", wb.getBytes());
HSSFWorkbook wb_test = new HSSFWorkbook(new
ByteArrayInputStream(blackboard.getAttachment(message.getQuery(),
"workbook")));
...
Any idea what goes wrong at this point!?
Kind regards,
Bogdan Sacaleanu.
