This one (even with model args) falls to the same category of
getting the inputstream actively. I do not see how I can
define the model to get data since the controlling side is
excelGen(outputstream). it keeps writing data to outputstream.
and I am trying to get it directly send back to browser.
It has to directly write to the response stream in a single thread
or it would block.
