Hi guys,

But if i will create a large excel file, it will cost a lot memory to get the 
whole workbook object ready before writing to file using workbook.write("***") 
. What's the best way to use poi to create large excel files? I donot think it 
is the best way to set a large heap of jvm. 
Need your help. Thanks!

Your friend
Yan
