Code i have written is
i am getting the inputstream from the FormFile of struts request
HSSFWorkbook wb = new HSSFWorkbook(is);


i'd appreciate developer's comments on whether this is indeed a bug and not some rudeness on the part of my own code,please

I do believe you might have possibly thought of the wrong kind of "Poi"? I'm not sure how many of the people here are actually developers (though we all do come from many different walks of life...) But this site is full of Artists/Dancers/Spinners who use Poi/Staff/Fans/Rope Dart/etc.. Poi being the tool best described as a pair of balls on lengths of chain/rope/fabric that is spun about... Hopefully there might be someone here that may be able to help but if not i hope you find your answer in some way.

maybe this site might be what you're looking for..?
