My suspicion is that exceptions like the ones described probably don't have anything to do with the type of InputStream you are using. The problems are probably due to corrupted file contents that would be visible using any other InputStream on the same file contents. If you *do* have a test case that fails in different ways depending on the type of InputStream please log a bug and supply the sample code and workbook file.
The errors described typically denote a corrupted file. Any random mutation of the data in a worksheet file which causes POI to throw these exceptions almost always causes Excel to fail to load the file cleanly. Having said that, there probably are a large number of unusual cases that Excel handles/tolerates but POI does not. If you have a file that Excel opens OK but POI does not, you should log a bug and supply that file. -josh --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@poi.apache.org For additional commands, e-mail: user-h...@poi.apache.org
