HSSF inside of a servlet - cannot create rows

[Chris McNeilly <cm...@smartbrief.com>]

This is very odd.

I have a class that modifies an existing spreadsheet.  When I call it 
from the command line, all is well.  It updates cells, it inserts cells. 
  A thing of beauty.  But, when I call the exact same code from within a 
servlet, I can update cells, but any time I attempt to insert a row, it 
craps out with an unhelpful trace that only points back to the createrow 
method.

Has anybody else seen this?  I've upgraded all the way up to last 
night's build, but it still has this problem.

Thanks,

Chris
