--- Comment #4 from Nick Burch <apa...@gagravarr.org> --- Try any other operating system other than Windows, and it should work just fine... The underlying OpenXML code supports in-place write, but XSSF does not, so your options are: * Use another OS * Write to a different file * Write a pile of code to allow XSSF to do an in-place update of the OPCPakcage Historically, HSSF only supported writing to a new outputstream because POIFSFileSystem didn't support updating streams within the OLE2 structure. These days, the replacement NPOIFSFileSystem does support it, as does the OPC code, but no-one has been bothered to spend the not insignificant amount of time to update HSSF and XSSF to do in-place updates of streams within open packages -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
