But how can I force WorkbookFactory to always use NPOIFSFileSystem?
Use the File constructor rather than the InputStream one, that use NPOIFS
My code is: Workbook wb = WorkbookFactory.create(new FileInputStream(filename));
Even if you didn't have a NPOIFS vs POIFS preference, you're much better off passing a File object rather than a FileInputStream - the File constructor is much more memory efficient than the InputStream one
(Ideally at some point we'll switch everything to using NPOIFS, but for now NPOIFS lacks write support and there's no volunteer energy to finish that last bit off)
